Seen upon the ground, the dark bird is scarcely attractive with his clumsy beak overbalancing a head that protrudes with stupid-looking awkwardness; but as he rises into the trees his lovely rose-colored breast and under-wing feathers are seen, and before he has had time to repeat his delicious, rich-voiced warble you are already in love with him.
Neltje Blanchan, 1897
First rose-breasted grosbeak of the season at the feeder (click photos to enlarge)
They’re back. Last Friday, April 22, I saw my first rose-breasted grosbeak at the feeder. Later in the day, there were three males at the feeder (and me with no camera handy). This is a few days earlier than I have seen them the past couple of years. Definitely one of my favorite spring migrants, the male rose-breasted grosbeak is certainly one of the most colorful birds to spend time at our feeders. They seem to prefer the open, platform-style sunflower feeder, but also visit the suet feeder with regularity.
The rose-colored, v-shaped patch, is in stunning contrast to their bold black and white
You can tell they are a favorite of mine, since I seem to post blogs about their arrival each season. I suppose it is a combination of things that make them so appealing – they are regular visitors at the feeders, they tend to stay at feeders for longer periods of time than most birds, they are relatively large with what seems to be an over-sized beak, and they have a stunning color combination. Add their melodious song, and you have a bird to remember, and one to anxiously wait for each spring. First to arrive from their wintering grounds in Central and South America are the colorful males. The brownish females will be along in a few days. Together, they will snarf up sunflower seeds for a few weeks, and then be gone by mid-May, on their way to breeding grounds farther north, or in the higher elevations of our mountains.
Male with some specklingMale with a lot of specklingMale with almost no speckling
Even if I had not seen all three birds on the feeder at once, I would know there are at least three in the yard, based on differences in their plumage. Supposedly, you can see subtle differences in the shape of the rose-colored patch on individual males, but these guys also differ in the amount of speckling on their breast feathers.
This one has a tiny rose speck near the eye
Granted, pictures of birds on a feeder are not my usual thing, but the feeders near the window are suspended on a pulley system out beyond the deck, making it more difficult to position branches and other natural posts for the usual “bird on a branch” photo at feeding stations. I owe all this to the incredibly abundant and pesky squirrels that share these woods (where is the red-tailed hawk when you need it?). The good news is that the birds are close enough to the windows to allow great views to appreciate their subtle differences and beauty. And, it is a definite perk to be sitting here with a cup of coffee, typing on the laptop, and looking out at the roses in the yard, even if it is for only a few weeks.
I too felt a slumberous influence after watching him half an hour, as he sat thus with his eyes half open, like a cat, winged brother of the cat.
~Henry David Thoreau, on watching an owl
I got a surprise email this week from a friend that had been one of my Yellowstone participants last summer. He told me about a barred owl nest that was on the golf course where he plays. A few years ago, there had been one on the course in the same tree and he was able to photograph the young on the day they left the nest cavity. He even published a children’s book about the owl nest. Some friends had told him they saw an owl going in and out of the nest cavity again this week. After speaking to officials at the club, he got permission to go out early, before tee time, to photograph the nest once again. The club is supportive of promoting bird conservation and awareness and is part of the Audubon Cooperative Sanctuary Program for Golf, an award-winning education and certification program that helps managers enhance the valuable natural areas and wildlife habitats that can be found on many golf courses. My friend knows I am a sucker for wildlife photo opportunities and was kind enough to invite me along.
What a barred owl nest cavity looks like about a minute after the owl flies off (click photos to enlarge)
I arrived at the golf course in the predawn light the next morning and we hiked out to the tree. I took my 500mm telephoto, a 1.4X teleconverter, tripod, and flash. I was carrying my gear in a backpack while my friend carried his rig already to go mounted on his tripod. Note to self, that is a better plan. When we arrived at the tree, the owl stared at the two early morning odd-balls and took flight soon after the first photo was taken (I was still assembling my gear onto the tripod, unfortunately). She probably is not used to people standing on the fairway this time of day. She flew across to some trees in a nearby backyard. In a few minutes, the owl let loose with a series of calls, including the monkey-like hooting and squawking I have heard so many times in the past. Shortly afterward, the owl cruised back toward the nest and settled on a branch within sight of the cavity.
Barred owl watching the nest cavity
Something soon caught her attention – there was a squirrel climbing up the trunk near the nest entrance. The owl sailed across, harassing the squirrel as it tried to run around the trunk and hide. After a quick spin around the trunk, the owl landed back on a large branch, only to dive after the squirrel once again when it resumed its climb up the trunk. This time the squirrel leaped across to another tree and moved far enough away to satisfy the protective parent, and the chase ended.
Once the normal activity of the grounds crew commenced, the owl seemed to calm down
A member of the grounds crew showed up near us and started grooming the area and blowing leaves. It seems that the familiar noise and movement of staff helped calm the bird. The owls are undoubtedly accustomed to this daily ritual near their nest and the passage of golfers throughout the day. Maybe we should carry a golf bag next time to ease her concerns.
Preening must be relaxing based on this look
After the squirrel chase, it seems that a good preening was in order.
Nothing like a good scratch in the morningOne feather at a time
We watched the owl preen for several minutes. At times, she almost seemed to doze off in the middle of a feather pull. I think Thoreau might be right…the slow, deliberate movements of an owl are reminiscent of a cat lying in a sunny window and surveying its world.
Heard something
After tidying up the feathers, the owl became more alert and was staring off in various directions for long periods of time.
Shortly after this video clip was made, the owl flew down to the fairway, sat for a few seconds, then returned to another branch with a large beetle. She soon took it into the nest cavity to presumably share with the young owls waiting inside. We waited, but the owl did not reappear, and I needed to leave for a meeting later that day at Pocosin Lakes National Wildlife Refuge. What a great way to start a day. Ironically, after the meeting, I was telling another friend about the owl incident and wishing I could find a screech owl in a similar situation. We drove around the refuge for a couple of hours and saw plenty of wildlife (bear, including our first new cub of the year, beaver, deer, etc.). As we made the final loop, I looked down the road and spotted something in one of the wood duck boxes next to the canal….
An Eastern screech owl peeking out of a wood duck box
Yep, an Eastern screech owl with its head poking out of the entrance hole. I have seen screech owls in wood duck boxes many times over the years, especially in winter. The usual thing is for them to wait until the car is almost close enough to stop for a photo and then they duck back inside. And this one was on the passenger side of the vehicle, so I had no chance at a photo. By the way, this proves that I don’t always have the wildlife on my side of the car as some have suggested:) As I pulled up, my friend got some great shots.
Checking me out as I eased the car forward
We decided to go down the road, turn around and see if I could get a few photos out my side of the car, although I fully expected the owl to disappear back into the box as soon as I pulled up. Well, it surprised me, and even turned and gave me a once over with a rather sleepy look on its face.
What a face
It finally turned, and pulled back in, and we drove on.
Owl or not?
As we pulled away, the sun was setting, and I saw what looked like another owl on top of a snag across the canal. But, it was just a very owl-shaped broken top to a dead tree. Still, a perfect way to end a day with the owls.
We find the works of nature still more pleasant, the more they resemble those of art.
~ Joseph Addison
This Spring has been incredibly beautiful here in the woods. Always a favorite time of year for me, it has been heightened by the almost perfect weather in recent weeks. The fresh green color of the season seems to sparkle in the sunlight streaming through the leaves. On the ground, there are daily discoveries to be made of something emerging from the leaf litter or starting to bloom. And while I have had plenty of chores and appointments to keep me occupied, I try to walk the yard as often as possible, and notice the players in this ephemeral show. If I pause and look around, there are always colors, shapes, and patterns that affirm that this is the month where new life bursts forth and beckons us to slow down and notice, before it disappears for another year.
Here are just a few indicators of the season from the past couple of weeks…

April is a beautiful time on the Haw (click photo to enlarge)
The Haw River flows along the boundary of the community where we live. It is a beautiful, rocky, river that flows 110 miles from its headwaters in Forsyth County, through Jordan Lake, to its confluence with the Deep River, where they combine to form the Cape Fear River. The Haw is also an important resource of recreation and drinking water for more than a million people in central North Carolina. Of course, it, and its river corridor, are also critical habitat for countless species in an area densely populated by humans. Over the years, the Haw has seen its share of pollution, from discharges from numerous textile factories a few decades ago, to runoff and nutrient overload from modern day development and other land altering practices within the river basin. The Haw River Assembly (HRA) has been educating people about, and helping to preserve, this valuable resource since its creation in 1982. I have always admired their work and diligence in standing up for the river. That is why I found myself joining a few other volunteers last Friday as we set out to do a stream monitoring assessment as part of HRA’s Haw River Watch Project.
Our monitoring site, just downstream from the Hwy 64 bridge
Our site is one that has been monitored off and on for several years. It is below the Hwy 64 bridge and easily accessible via a trail from the canoe access parking area.
The rest of our monitoring team doing chemical analyses
That is a good thing, since there is a bit of equipment to tote to your site – nitrate and phosphate test kits, petri dishes, magnifying lenses, a turbidity tube (for measuring water clarity), and a variety of nets and pans for sampling macro-invertebrates.
Juvenile northern water snake greeted us at our site
In addition to the water chemistry analyses, we survey the biology at our site. The primary assessment is for macro-invertebrates, which are used as indicators of water quality. But we are also take note of any other wildlife species. Shortly after we arrived, Elaine spotted a juvenile water snake sunning on a rock. Nearby was a small cloud of Eastern Tiger Swallowtails puddling for minerals along the bank of an island in the river channel.
Mayfly nymph pulled form underside of a rock in the river
But what we really wanted to learn was what was in the river, so most of us waded out into the water, sampling with nets as we went, and trying not to slip on the slick diatomaceous slime coating most of the boulders. This slippery surface is caused by a coating of algae and associated organic matter that coats the outside of underwater rocks and logs, especially in the slower moving portions of the river. It is an important food source for many macro-invertebrates, but can make for tricky footing for river monitors (it helps to have a long-handled net to brace yourself). I walked out a few steps and picked up a softball-sized rock in about a foot of water. Turning it over, I found two mayfly nymphs clinging to the underside. They were both very flattened, an ideal adaptation for living under rocks in swift water.
A mayfly nymph in the family Heptageniidae
Almost any small rock that could be turned over had one or more of these flattened bugs crawling about. As any trout fisherman knows, mayflies often constitute one of the primary food sources for fish in flowing waters. They belong to a family of insects called Ephemeroptera, derived from the Greek “ephemera”, meaning short-lived, referring to the short lifespans (hours or days) of most adult mayflies. North Carolina has over 200 species of these fascinating insects. As a group, they vary a great deal in size, shape, and habit, but can be distinguished from other macro-invertebrates by the presence of three (sometimes two) tail filaments, and gills along the sides of the abdomen.
Tiny mayflies were the most common invertebrate we netted
As it turned out, mayflies were, by far, the most abundant organism we collected.And most of them were very small ones that resembled this tiny guy. I am not sure, but I think it is a member of the family Baetidae, one of the most abundant types of mayflies in North Carolina.
Looking across the river at our sample site
Much of the river bottom is exposed rock outcrop and boulders with fast flowing water. Our most productive sampling occurred closer to shore or in areas with vegetation.
Underwater view of vegetation on a boulder in the river
I found myself going back to details I learned in classes I took years ago at Virginia Tech to try to identify (at least on a broad scale) many of the critters we uncovered. But a few things threw me and required some additional sleuthing. An early find resembled a globular egg mass on a tiny twig, but, when I discovered a more complete specimen, turned out to be a water-logged cluster of sweet gum flowers (duh). But another mystery proved to be something more worthwhile.
Small brown cases lined up on leaves of underwater vegetation
Some leaf fragments of some underwater plants ended up in my net and they had several small brown case-like structures adhered to them.
Closer view of cases
When I magnified the image back home, I could see white strands on one end of the case. This reminded me of the tracheal tube remains you see in a shed skin of a cicada nymph, so I assumed this was some sort of pupal case or shed skin of an aquatic critter.
A close up view of the underwater vegetation helped solve the mystery
When I took a closer look at the underwater image from the spot where these cases were collected, I saw a line of black flies lined up on one of the leaves. I then found some images online that suggests the cases are pupal cases of black flies.
Black fly larva
A few of our samples contained some of the distinctive fly larvae. The larvae produce a silk pad and then attach to it with tiny hooks on the tip of their abdomen.
A huge dragonfly nymph was the catch of the day
The best catch of the day was a huge dragonfly nymph. The broad abdomen of this species is diagnostic, and probably helps hide the nymph among the underwater bark and leaf debris it calls home.
Dragonhunter nymph
This is the distinctive aquatic stage of the dragonhunter, Hagenius brevistylus. Dragonhunters are the largest of the so-called clubtail dragonflies in the family Gomphidae. Adult dragonhunters, as the name implies, feed on other dragonflies and other large insects such as butterflies. The immature stage is easily recognized by the huge abdomen and “mickey mouse ears”, which are actually short, rounded antennae. The nymph is exceptionally long-lived, staying underwater for 4 or more years before emerging as a winged hunter.
Another dragonfly nymph
In that same spot, we found another, smaller, dragonfly nymph. Something we noticed about both of our dragonfly specimens was the abundance of tiny tubes covering their body.
Mystery tubes on dragonfly nymph
I’m not sure what they are, but they resemble the mud or silt tubes made by certain species of chironomid midge larvae. If anyone knows for sure, please drop me a note in the comment section. Our samples turned up quite a variety of macro-invertebrates, enough that the water quality index for this site was rated excellent. Below are a few more of the denizens of the Haw we found in our nets…
Large mayfly nymph, possibly in the family IsonychiidaeCaddisfly larva, family Hydropsychidae
Dobsonfly larva (also called a hellgrammite)Shed skin of a stonefly nymphAquatic isopod
We will be sampling again in a few months and I can’t wait to see what we find. We all hope the river can maintain its beauty and diversity of life in the face of increasing pressures within the watershed. And we all owe a huge thank you to the many people and organizations (like the Haw River Assembly) that work so hard to help protect this, and the other waterways, of our state.
There’s so much for you to see outdoors. The one requirement, you have to be there to see it.

The first bison calf of the season was reported yesterday from Yellowstone National Park. It is the first of many hundreds to be born over the next couple of months. Act now and you can join me to view these babies, and much more, on the trip of a lifetime to one of the great wildlife-viewing areas in North America. Join me June 2-9, 2016, for another great trip to explore the world’s first national park. Details and registration information are on my trips page.
Spend time watching wildlife in one of the world’s great natural areas
With the exception of a body of rocks looking like the ruins of an old castle, near the southwestern extremity, the top of Roan may be described as a vast meadow, without a tree to obstruct the prospect; where a person may gallop his horse for a mile or two, with Carolina at his feet on one side and Tennessee on the other, and a green ocean of mountains rising in tremendous billows immediately around him.
~Elisha Mitchell, 1835
The Celo Inn (click photos to enlarge)
Last weekend we took a mini-trip to the mountains on short notice. Original plans were to travel to South Carolina, but weather reports called for rain much of the weekend. A last minute change of schedule had us headed to one of my favorite spots in our mountains to spend a night or two – the Celo Inn. Located near Burnsville, the Inn is both simple and elegant. I have stayed here many times over the years, including on several museum workshops, and it has always been a pleasure. The innkeepers are wonderful folks, and the breakfasts are a delight. Plus, the location, just a few miles off the Blue Ridge Parkway, is ideal for all sorts of mountain adventures.
Roaring Fork Falls
After checking in, we headed to a nearby waterfalls for a short hike before dinner. Roaring Fork Falls is a 100 foot cascade up an easy 1/2 mile trail. It is a well-used area but is still a beautiful setting. Unfortunately, all of the hemlocks at the falls appear to now be dead from the effects of the introduced Hemlock Woolly Adelgid. It makes me wonder what impacts there have been (or will be in the future) on the aquatic life in this, and so many other beautiful mountain streams. Shade cast by the dense canopy of the large hemlocks helped cool the temperatures in the streams and, undoubtedly, provided a lot of organic input every year. Only time will tell how these mountain streams will fare without the hemlocks along their banks.
The sinuous track of this tree root reminded me of the path of the water cascading beside usA slow shutter speed creates a misty flow in the cascadeThe reptilian texture of liverworts growing on a stream-side boulder
Just sitting by a clear ribbon of water is a soothing way to spend time, and helps me take in the scene more clearly. I think I notice subtleties better when listening to flowing water.
A red spruce grove near the start of the trail up Roan Mountain
The next morning we drove about an hour to a new area for me, the so-called highlands of Roan Mountain. The Appalachian Trail (AT) crosses the road at Carver’s Gap and heads up on both sides to a unique habitat in the Southern Appalachians – mountain balds. We arrived at the trail head to discover it really is one of the more popular hiking destinations in the region. I am guessing there were 40 or 50 vehicles parked in the lot and along the roadsides. The guidebook said most people only walked to the top of the first bald and, beyond that, the trail would grow less crowded. We headed north along the AT, crossing through a dense grove of red spruce, before breaking out into a clearing bordered by rhododendron.
The trail soon becomes a pathway in the sky
Mountain balds come in two flavors – grass balds and shrub (or heath) balds. The term “bald” here refers to mountain summits that are covered in grasses or shrubs where you would normally expect to find forests. The origin of these treeless areas is still a mystery, although current theory suggests that grazing by large native herbivores (some of which, like ground sloths and woolly mammoths, are now extinct) in prehistoric times, and later by elk, bison, and introduced livestock with the arrival of settlers, has maintained these unique vegetative communities. Whatever their origin, they are a hiker’s delight. But, conditions are changing and shrubs are beginning to encroach on many of the grassy balds in the region. Land managers are trying various strategies (grazing, mowing, hand cutting) to maintain these scenic vistas.
View across the grassy balds of Roan Mountain
Along our section of trail, there are three high elevation balds – Round Bald (5,826 ft.), Jane Bald (5,807 ft.), and Grassy Ridge (6,158 ft.). This section of trail across the Roan highlands is said by many to be the most scenic section along the entire 2000+ mile Appalachian Trail.
Trail sign at Jane Bald
The trail literally straddles the NC-TN state line as it gradually climbs over the ridges. Along the way, you pass through a few shrub-dominated zones containing Catawba rhododendron, green alder, and blueberries.
The trail passes under a rhododendron tunnel
After Jane Bald, the AT veers off down a slope, but we continued on a well marked trail up toward the summit of Grassy Ridge. In a scene reminiscent of my recent Everglades trip, we passed under a tunnel of vegetation, but this time it was rhododendron, instead of red mangroves, brushing my hat.
Rhododendron thicket along trail reminded me of an upside down mangrove thicket
After the short stint of ducking under low branches, you come out into a vast open area, which keeps getting more spectacular as you climb.
You can’t beat the views from Grassy Ridge
This is Grassy Ridge, and on a clear day, waves of undulating lines stretch out before you – Grandfather Mountain, Table Rock, Hawksbill, and countless lesser known peaks and ridges that seem to go on forever. This is why this section of trail is so popular. I can only imagine what it must be like in late June when the rhododendrons are in bloom, along with the occasional rare Gray’s Lily. I suppose I will need to return to see for myself.
Nature is painting for us, day after day, pictures of infinite beauty, if only we have the eyes to see them.
~John Ruskin
While we saw a variety of wildlife on our Florida adventure, I was a bit surprised we had not seen as many birds as I had hoped. As I mentioned in an earlier post, it has been a wet winter in South Florida, which apparently causes the birds to be more spread out than usual during the winter months.
Great egret preening in Big Cypress
There had been plenty of scattered sightings (and some great views) of egrets, herons, hawks, and song birds, but no large concentrations. On our last evening in Florida, I was hoping to change all that. On the advice of our kayak tour company, I had booked a sunset boat tour with Allure Adventures out of Everglades City. I was told Captain Kent was a long-time local that took small groups out to the mangrove islands at sunset with the chance of seeing lots of birds coming to roost, beautiful skies, and maybe even dolphins and sea turtles. He lived up to the promotion.
A nice Florida combo – osprey nest on a manatee zone sign in the channel
We met him at at the dock at 5:45 p.m., boarded his small boat, and headed out into the area known as Ten Thousand Islands. Close to shore we saw pelicans, a few egrets, some cormorants, and passed by a couple of osprey nests.
One of several mangrove islands filled with birds coming to roost at sunset
Within a few minutes, we saw a cluster of mangrove islands dotted with birds, lots of birds.
Great egrets settling in for the night
As our boat slowly circled the islands, I could see hundreds of great egrets, brown pelicans, white ibis, cormorants, and other species jostling for position as more of their kind flew in to roost for the evening.
Adult born pelican surveying us as we cruise by the islandAdults have yellow heads and white necks; immature pelicans are gray-brown on their head and neck
Boats are required to stay a certain distance away from the roosting birds so as to not disturb them. Our slow speed, the calm waters, and a telephoto lens (plus a cropped image) allowed great views and close-ups.
The last mangrove island before the vast expanse of the Gulf of Mexico
Promising we would return before sunset, the captain steered us out through a maze of islands until we came to the edge of the Gulf of Mexico. We beached the boat and got out for a stroll for a few minutes to take in the view and immensity of the scene.
Dolphins riding our wake
Cruising back toward the birds, we spotted a couple of sea turtles, and a small group of dolphins. As we passed through the area where the dolphins had been swimming, the captain said they often like to “play” with the boat. Sure enough, it wasn’t long until we had dorsal fins trailing in the wake of our boat, with dolphins taking turns leaping out of the water behind us.
I’m not sure who enjoyed it more, the dolphins or us.
Cruising through the mangrove islands at sunset
We spent several minutes enjoying the company of the dolphins, but the captain soon turned the boat back toward the bird islands. The sun was setting and he wanted us to see how many more birds were now occupying the mangroves.
Hundreds of birds dotted the mangroves at sunsetBirds were flying in to roost from all directions
As we approached, the trees were speckled with white and dark shapes, with more coming in from all directions.
Spectacular scene at sunset
White ibis coming in to roost
The color of the sky became a flame orange as we circled the islands one last time. This was what Captain Kent wanted us to see…the bird rookery with a golden sky as a backdrop.
Some of the egrets are busy building nests in the mangroves
It was a perfect way to end our trip – calm waters, a beautiful sky, and huge numbers of birds flying in for the evening. This was what I had hoped to see, the spectacle of wild Florida. And I must also thank Captain Kent for going above and beyond the call of duty. One of our party left behind a pair of rather expensive binoculars, presumably out on the mangrove island we had walked on. The captain made a special effort to look for them on his next outing, and, amazingly, found them. They have been shipped to the owner, and we all thank him for an amazing trip, and his kindness. Now, that IS the perfect ending.
If, in the name of progress, we want to destroy everything beautiful in our world, and contaminate the air we breathe, and the water we drink, then we are in trouble.
~Marjory Stoneman Douglas, in response to critics saying that conservationists were trying to halt progress in Florida by preserving Big Cypress Swamp
Big Cypress National Preserve was once called the Western Everglades, and was originally supposed to be part of the national park, but was removed from protection before the park was created in 1947. An elevation difference of 1 to 2 feet makes Big Cypress a vastly different ecosystem than the river of grass of much of the eastern portion of Everglades National Park. Big Cypress is home to deep water cypress sloughs and strands (linear cypress islands) and is underlain more by peat than the limestone deposits more common in much of the park. The result is more of a “swamp feel” than the open grass prairies we experienced on our first two days in Florida.
Pond behind our lodging in Big Cypress (click photos to enlarge)
It wasn’t until I returned home that I found out about the contentious history of the effort to preserve what is now Big Cypress National Preserve, the first national preserve in the United States. After the virgin cypress were essentially logged out throughout much of the region in the 1930’s and 40’s, the area was proposed as part of Everglades National Park. But, when the park was created, the lands encompassing Big Cypress were excluded. More controversy erupted in 1968, when plans were unveiled to create a huge jetport (what would have been the largest airport in the world) in part of Big Cypress. Conservationists joined the fight and the struggle went back and forth until the creation of the 720,000+ acre preserve in 1974.
Our Swamp Walk guide, Scott, pointing out an alligator at the end of our trail
When planning the trip a few months ago, I learned about some unique lodging in an in-holding in Big Cypress – the cabins at the Big Cypress Gallery of famed landscape photographer, Clyde Butcher. I have been aware of Clyde’s images for many years and he really is the Ansel Adams of the swamp. He is also an ardent conservationist, and has done a great deal to bring the beauty and plight of the region to the public’s attention. When I found out he had lodging in Big Cypress, I couldn’t resist booking it. In addition to the wonderful accommodations and surrounding property, he offers guided swamp walks for a fee. Though it is a bit pricey, I am glad we did it. Our guide, Scott, is a wonderful person (as were all the staff we met) and very knowledgeable about the plants and animals of Big Cypress. The swamp walks usually take a couple of hours. You walk with a sturdy hiking stick (they provide those) on a flooded trail behind the lodging that passes through a variety of habitats, including swamp, prairie edge, and dwarf cypress stands. There was both excitement and some slight apprehension when we began the hike, and I particularly liked Scott’s answer to the question, “how deep does it get”? He said this winter has been unusually wet, so the deepest part was 38 inches. Nothing like a precise answer! Of course, he is 6 feet 5 inches tall, so the deep water comes a little farther up on our bodies than it does on his.
Bromeliads are very abundant in Big Cypress
We walked at a slow pace, taking in all the sights, and sounds, that the swamp had to offer. The grunting calls of pig frogs were particularly evident here as they were elsewhere on our trip. And the diversity of plant life is amazing!
An old growth cypress stand looks quite different than our old growth forests
At one point, the trail opened up into a mix of small cypress trees and grasses. Many of these trees are surprisingly old, stunted due to growing on the porous limestone bedrock of this particular part of Big Cypress. We saw relatively few animals until we got right to the end of the trail.
Large female alligator greets us at trails’ end
There, in a small pond behind one of the cabins, was a large female alligator (maybe 7 ft+ in length), along with several of her babies and a few 1 and 2 year old gators. She came over to greet us as we stepped out of the swamp onto dry ground, and hissed loudly to let us know we should not disturb her youngsters. Not to worry, we gave them a wide berth.
Big mama watching us as we look back
Gators have a toothy grin when viewed through binoculars or a telephoto lens, enough so that you respect their space…
A sign that states the obvious
and shouldn’t need to be reminded with signage:) We did all wonder what it must be like to live next to such large reptiles. I will admit, I scanned the surroundings with my flashlight more than usual when I went outside at night.
Ovenbird
Neotropical migrant birds are beginning to appear in South Florida (and should be here in NC soon, if not already). On a short walk at our lodging, I saw Northern Parula Warblers, Blue-gray Gnatcatchers, a Louisiana Waterthrush, Black-and-white Warblers, and several Ovenbirds.
My kayak buddy at sunrise on the Turner River
Our first full morning in Big Cypress was spent with Shurr Adventures on their sunrise kayak tour on the Turner River Paddle Trail. I had picked this group since they were highly rated online, and I saw they do Yellowstone tours in the summer (how could I go wrong with that combo?). It turned out to be a great choice. The kayaks were very stable, with comfortable seats, and the guide was very personable and knowledgeable. The morning started out foggy, and we saw, and heard, lots of wildlife.
Common moorhen on the riverThis green heron allowed a close approach while it squawked its guttural callOsprey near its nest on the river
All sorts of bird life was active that morning, and the kayaks allowed us to get close to several species. When we headed south of the put-in point, we even got a pretty good view of one of my target species, a limpkin (unfortunately it was in thick vegetation , so not the best photo op).
Exotic apple snail (left; smaller, native apple snail (right)
Florida is awash in exotic invasive species, both plant and animal. While paddling the Turner River, we were introduced to one of the more recent invaders, the island apple snail. Believed to have been introduced by releases from the exotic pet trade, this, and a few other species of exotic apple snail, are creating real concern for scientists in the Everglades. The native Florida apple snail, Pomacea paludosa, is much smaller than this invader, and is the primary food source for the endangered snail kite. The larger size, fecundity, and voracious appetite of the invader snail, P. insularum, is cause for concern, both in terms of altering the wetlands plant community, and out-competing the native species of snail, with potentially disastrous results for the kite.
Egg masses of the exotic island apple snail are pink; eggs of the native species are larger, and white
During our stay, I found one egg mass of a native apple snail, but we saw many egg masses of the invader, especially in the Big Cypress Swamp area.

When we headed south of the Tamiami Trail in our kayaks, the plant community changed from a cattail fringed swamp forest to an expanse of red mangrove tunnels. Kayaking through the mangroves turned out to be a lot easier than paddling a canoe through them, like we had done at Nine Mile Pond, but you did need to break down the longer kayak paddle to avoid catching it on every prop root. After finishing our morning trip, we returned to Clyde Butcher’s place for some rest and exploration. I drove out to scout our route for our final day in the area (a dirt and paved thoroughfare called the Loop Road), and came across all sorts of birds and a seemingly endless supply of alligators. If you have the time, I recommend the Loop Road as a leisurely pathway to observe some of the scenery and critters of Big Cypress. The entire wild region was a great way to relax before heading back to the hectic pace of Miami for our flight home. Below are some more images of our time in Big Cypress. I look forward to a return visit in the near future.

There are no other Everglades in the world. They are, they have always been, one of the unique regions of the earth, remote, never wholly known.
~Marjory Stoneman Douglas, author of The Everglades: River of Grass, 1947
Sitting by the fire yesterday afternoon, I can hardly believe I spent last week in the Florida heat and humidity, in one of the most extensive wild places I have ever been – Everglades National Park. Years ago, I drove across the state on I-75 (aka Alligator Alley) going from Miami to Tampa Bay, but I had never been in the park. So, it didn’t take much convincing when a group of friends asked if I wanted to join them on a trip. After flying into Miami (and getting a bit lost trying to get out of the city), it is a relatively quick drive through extensive farm fields, of every imaginable type of crop, to the sudden transition to the park.
The Anhinga Trail can be crowded, but still has great wildlife (click photos to enlarge)
Our first must-see stop was the famed Anhinga Trail, on the east side of the park. It is not far from the entrance and is said to be one of the best places to see some of the park’s iconic wildlife up close and personal. And even though it was crowded with visitors (and, I am happy to report, several school groups), it did not disappoint.
Double-crested cormorant along the trail
After spotting an alligator near the trail head, we walked by a double-crested cormorant, standing right next to the paved trail, and panting in the 80+ degree heat. I shot several close-up photos before moving on. I must admit, I always love seeing their emerald green eyes.
Feather pattern on the cormorant
This bird was so close to the trail, and seemingly so unafraid, that it also allowed me to appreciate the delicate feather pattern on its back.
Great egret hunting next to trail
A few feet further along, a very tame great egret was hunting in a culvert that passed under the paved trail and spearing small fish. This time of year is the start of their breeding season and these elegant birds undergo a dramatic color change on their face – the lores (the skin between the eye and bill) turns from the usual yellow to a chartreuse green, and the bill changes from yellow to blackish-orange. They also develop long nuptial plumes, called aigrettes. These elegant feathers almost led to the extinction of egrets by plume-hunting in the early 20th century, when the feathers were used to adorn ladies’ hats. Luckily, conservation efforts helped stop the demand and the birds have recovered over much of their range.
An anhinga, with wings spread, along the boardwalk
Walking out on one of the boardwalk sections, we spied numerous green herons, some more alligators, and the trail’s namesake, an anhinga. Anhingas are oddly beautiful birds that go by other names such as water turkey (their tail does resemble that of a wild turkey) and snake bird (for their habit of swimming with just their neck and head above water). This wing spreading behavior is to allow them to dry their feathers after swimming for their favorite prey, fish. Anhingas and cormorants are primitive birds that lack the oil glands to waterproof their feathers that other water-loving birds possess. During the breeding season, the skin around their eyes turns a bright blue.
Halloween pennant
Probably the most common flier we saw was not a bird, but a species of dragonfly, the Halloween pennant. It is easily recognized by its distinctive wing colors – orange with dark splotches and bands. It is often seen perched atop vegetation, swaying in the wind.
Blue tilapia
The clear water allowed us to see many species of fish along the canals and pools throughout the park. At the Anhinga Trail, one of the most common was baffling at first. It turned out to be an introduced exotic, the blue tilapia, native to Africa and the Middle East. These fish were everywhere in the canals and their large excavated nests were clearly visible in the dark water. South Florida is, unfortunately, a haven for all sorts of exotic plant and animal species. A few native fish species are also very abundant and easily observed including largemouth bass, various species of sunfish, and Florida gar.
Strangler fig
While many of the birds and other wildlife are species that I found familiar, many of the plant species in this portion of the park are more tropical in origin, but were vaguely familiar from my museum trips to Belize years ago. One we saw throughout our travels is the bizarre strangler fig, Ficus aurea. The life cycle starts when a bird or other animal eats the fig fruit and deposits the sticky seed on the trunk of another tree. The fig often begins as an epiphyte, but soon sends roots twining down the trunk of its host to reach the soil. It then grows to the top of the host, sends down aerial roots, and leafs out in the crown of the tree, shading out the leaves of the host plant. The fig continues to develop its crown and root system, often completely enveloping, and eventually killing, the host tree.
On our second morning, I had arranged a ranger-led canoe trip at Nine Mile Pond. We had 6 canoes, plus the ranger, on a 4 hour paddle through mangrove tunnels and marshes.
Mangroves and marshes along the paddle trail
We started with a fantastic sunrise and enjoyed numerous alligator sightings, a gentle breeze that helped with the rising heat, and blue skies punctuated by white puffy clouds.
Another alligator gives us the eye
The highlight for me was some serious alligator bellowing at one of our stopping points. It is the start of the gator breeding season and the big bulls bellow to attract a mate. It is one of the most impressive wild sounds in the southeast, reminding me of a roar of a lion or a bison bull.
Can you find and identify the three bird species in this tree?
The road through this section of the park ends at Flamingo, a small enclave along Florida Bay with a marina, visitor center, and cafe. We spent time here on both of our first two days, enjoying the breeze and the abundant bird life. Osprey nests dotted the trees, mangrove islands, and man-made towers. At one point there were three great bird species in a tree near the parking lot – an osprey in its nest, a red-shouldered hawk, and a pileated woodpecker. Out in the Bay, we spotted American white pelicans, white ibis, brown pelicans, black skimmers, and numerous gulls, terns, and shorebirds. And, on a stroll to the marina (without my camera, unfortunately), we had great views of a huge American crocodile (this is the best place in the park to see this rare reptile) and four manatees. Needless to say, Flamingo is well worth the drive.
Vast saw grass prairie at Pa-Hay-Okee boardwalk
When I started planning the trip, I bought a copy of Exploring Everglades National Park and the Surrounding Area (A Falcon Guide), and it proved a valuable asset in choosing which of the many trails and boardwalks to visit in our brief stay. One of the highly recommended stops is the Pa-Hay-Okee Trail. The name is derived from a Seminole word meaning “much grass in water”, a reference to the vast saw grass prairies that make up much of this region. There is an elevated section to the boardwalk which gives an incredible view of the “river of grass” that is the lifeblood of the Everglades.
Little blue heron up close
Another must-see stop is Shark Valley. We arrived mid-morning and drove right in (there can be considerable wait times to get in on busy days – but you can drop your riders off and park along the main road outside the entrance and walk back in). There is a small visitor center, restrooms, a few picnic tables and a 15-mile paved trail (accessible by walking, bicycling, or taking a concession-operated tram tour) through the saw grass prairie. Along the trail is a canal that retains water even in the dry season, concentrating wildlife such as alligators and wading birds, for easy viewing. Even though this winter has been an unusually wet one, which has caused much of the wildlife to remain dispersed throughout the vast wetlands, there were still plenty of things to see as we walked a short distance along this easy path. A little blue heron hunted patiently within a few feet of the walkway, periodically snapping up tiny fish and gulping them down. Several species of warblers and other songbirds were seen and heard in the thickets along the canal (especially the ubiquitous white-eyed vireo).
Purple gallinule
And we finally caught a glimpse of one of the “specialty birds” of this trail, a purple gallinule. These brightly-colored members of the rail family feed on a variety of plant material and invertebrates. Their enormous feet are useful for clinging to shrubbery and walking on floating vegetation such as lily pads.
The first of many baby alligators we saw
Alligators were all along the canal, and we even had several baby alligators sunning themselves on lily pads. One walked across the pavement, as people stopped and wondered where the usually protective mother gator might be hiding and watching her brood. After a brief stay at Shark Valley, we headed out of the park and to our next destination, Big Cypress National Preserve. I feel like I only scratched the surface of the Everglades experience. It is the third largest national park in the continental United States at 1.5 million acres and is one that lies just outside the major metropolitan areas of Miami and South Florida, and the huge agricultural lands that provide food for countless Americans. Even though the park represents a large portion of land, the ecosystem is highly altered from its original condition. Roads and drainage canals have greatly reduced the flow of water from lands north to Lake Okeechobee, and agricultural chemicals are impacting the water quality. But, the Everglades still present a wild side of Florida that people need to experience. A visit to this park helps you understand why we must all continue to work together to protect out public lands and the incredible diversity of life that call them home.
While walking down by the intermittent stream in the woods this week, I caught a flash of movement out of the corner of my eye. I turned, but didn’t see anything at first. When I stepped in the direction of the flash, it happened again. This time I saw it – it was the quick escape leap of a tiny northern cricket frog, Acris crepitans.
Northern cricket frog (click photos to enlarge)
They are among our smallest vertebrates, with adults barely reaching 1.5 inches in body length. But they are great leapers for their size, jumping up to three feet when startled.
Cricket frogs blend in very well with their surroundings
Northern cricket frogs are widespread in the Eastern U.S., ranging from northeastern Mexico, up to Wisconsin, and east to the Atlantic states. There are actually two species of cricket frogs in North Carolina – the northern, which is mainly in the Piedmont, and the southern, more typically found in the Coastal counties. They are similar in appearance, both being small, cryptically colored frogs, with long, slender hind legs, and a warty appearance. Most have a distinctive darkened triangle pattern between the eyes, and a Y-shaped line extending down the back. Throughput their range, northern cricket frogs exhibit variation in color, with the dorsal stripe being either primarily gray, brown, reddish-brown, or green. The one above seems to be primarily brown with some hints of reddish-brown in some of the warts.
Another frog in these woods with a green color pattern
A few yards away, I came upon another cricket frog, this one with a noticeable green coloration in the dorsal Y-pattern. I looked up the topic of their color variation and stumbled on a host of scientific papers dealing with this phenomenon in cricket frogs, known as color polymorphism. Various theories have been proposed and tested throughout the range of this species. And they have come up with various reasons for the color differences: visual selection by predators directly determines color proportions (the theory being that those that blend in better with the local surroundings are better concealed and therefore survive better); another thought some color morphs correlated better with local substrate color but are more resistant to desiccation in certain habitat types; and yet another study disagreed and suggested natural selection may favor some behavioral characteristics associated with a particular morph.
Whatever the reason for their color, they are fun to watch
I finally found one Illinois study that did some comparisons with other data and concluded that different factors must operate throughout the species range to maintain this color polymorphism. The author states that chance may be a major factor in determining color morph proportions in localized populations. Perhaps the frogs know something about color variation that we just have not yet discovered. Whatever the reason, I always enjoy seeing one of these cryptic creatures leap and disappear into the background. And, I look forward to the start of their breeding season, accompanied by their clicking calls, in a few weeks.
