• A Frog in My Throat

    Frogs are the birds of the night.

    Henry David Thoreau

    There is something magical about the sounds of frogs and toads. In my museum days, I used to do a workshop activity where participants got a call sheet for a local frog or toad species. Each sheet had a photo and a description of the amphibians’ song. Teams imitated their call and then we would listen to a recording, and each group would try to identify their species’ real call. People always loved imitating the sounds and hearing the recordings, but few could match the quality of the actual amphibian voice.

    Part of the reason may be the special adaptations that frogs and toads have for communicating with one another. The most visible asset is their vocal sac.

    The vocal sac is an elastic membrane originating from the floor of the mouth of most male frogs. It tends to be thinner on many of the smaller frog and toad species that call in air, and more thick-walled on the larger species, like Green Frogs and Bullfrogs, that call in water. Vocal sacs come in a variety of shapes and sizes, and can be single or paired. To initiate a call, a frog inflates its lungs, and closes its mouth and nostrils. Air is then forced out of the lungs through the larynx and into the vocal sac, which then enlarges. To create the series of sounds typically categorized as the advertisement or mating calls, the air is passed back and forth from the vocal sac to the lungs without being expelled. While it appears that the vocal sac helps to radiate and amplify the sound, studies have shown that other body parts, especially the “ears”, or tympanic membranes, also play an important role in amplifying the call notes of certain species.

    When seen from behind, as in the short video clip below, it is clear that this sound-producing activity must be a lot of work for a male frog.

    Some scientists also speculate that the act of calling is both the most energy-draining and predation-risky behavior that a male frog or toad exhibits. But, aren’t we glad they do? It is a fascinating behavior to observe, and the sounds produced are a wonderful addition to our natural sound-scape. I imagine the female frogs and toads appreciate it as well.

    Below are a few photos I have taken over recent years of frogs and toads calling in a variety of habitats in North Carolina. I look forward to adding photos of more species in the coming months.

    The Pickerel Frog has paired lateral vocal sacs that produce a low-pitched call sounding like a human snore.

    One of our earliest frog songsters, the Spring Peeper repeats his high-pitched note about once every second. One reference stated that researchers estimate a male Peeper may repeat his call up to 4,500 times in a single night.

    The harsh trills of the Cope’s Gray Treefrog can be heard in many North Carolina forests and neighborhoods throughout much of the summer.

    Considered by many to be our most beautiful frog, the Pine Barrens Treefrog is found primarily in the Sandhills. It became the Official State Frog in North Carolina in June, 2013.

    Fowler’s Toads are abundant in the Piedmont. Their nasal call (“waaaaah”) can be heard from about April through July.

    A chorus of trilling American Toads always reminds me of what a group of distant alien space ships might sound like in early sci-fi films.

    Thoreau (no surprise here) had a more eloquent take on the sound of the American Toad…

    Close by, it is an unmusical monotonous deafening sound, a steady blast (not a peep nor a croak – but a kind of piping). But far away, it is a dreamy, lulling sound, and fills well the crevices of nature.

    Thoreau also had some intriguing insights on how we may share some similarities with the amphibians singing in our neighborhood wetlands…

    I see the relation to the frogs in the throat of many a man. The full throat has relation to the distended paunch.

    Not sure where ol’ Henry was going with that one, but this final thought seems clear enough…

    The music of all creatures has to do with their loves, even of toads and frogs. Is it not the same with man?

  • Woodland Chorus

    What is the earliest sign of spring? The motion of worms and insects? The flow of sap in trees and the swelling of buds? Or are there earlier signs in the water? – the tortoises, frogs…

    Henry David Thoreau, March 7, 1853

    I think the sounds of the coming spring are amongst the first things I notice. The bird songs, the whir of insect wings, the busy rustling of leaves as squirrels begin making their spring nests. Even the breeze sounds different on a warm, late winter day. But one of the surest signs of the warmth to come are the calls of our early amphibians. Here in the forests of the Piedmont of North Carolina, that role is usually handled by Spring Peepers and Upland Chorus Frogs. I started hearing the chorus frogs a few weeks ago, before the last snow and deep freeze. They took a break while their world turned white, but now they are back on duty, proclaiming a change is in the air. I have spent some time over the past several years trying to photograph various species of frogs and toads as they fill the air with their distinctive mating calls. I have had some good success, but one species has managed to elude me – the Upland Chorus Frog, Pseudacris feriarum. I find it both difficult to approach and difficult to observe when calling. They tend to call from shallow water in vegetated pools, often hiding amongst the vegetation as they sing. At my approach, they invariably fall silent, requiring a quiet sit and wait strategy on my part before they call again, if at all. So, I was determined to try again this week after hearing a fair number of them calling in several woodland pools while on my walk this past Sunday. Using binoculars, I watched a few calling at a distance of 30 or more feet in one large pool. I also found several of their small egg clusters attached to some twigs and grasses in the water.

    I even saw a pair in amplexus, that amphibian embrace where the male clasps the female from above and fertilizes the eggs externally as she releases them. But, the calling frogs were either too hidden in thick vegetation or too far out in the pool for a good photograph. Walking down through the floodplain I soon heard another loud chorus coming from behind a ridge line that angled toward the stream. As I climbed over the top for a look, I saw a small pool that contained a dozen or more calling frogs.

    Woodland pool
    Woodland pool with Upland Chorus Frogs

    I sat and watched and decided this pool had potential – there was a large tree on one edge that wold provide a bit of cover. The pool was small and the sun would be coming over my shoulder late in the day, so the chances for good photographs seemed likely. Even though the frogs had started calling again shortly after I initially walked up, I was a bit concerned that when sitting against the tree trunk, I might be too close, and that might really spook them. So, the next afternoon I brought my Kwik Camo blind (http://www.outdoorphotogear.com/store/kwik-camo-photography-blind.html). I thought it would allow me to better blend in, so the frogs might start calling again even after I brazenly walked into their concert hall. The blind fits nicely in a belt pouch and is lightweight, so it is easy to strap on and carry for long hikes. Plus, it drapes over my camera, tripod, and my human form, and turns me into an amorphous bush that hopefully looks less threatening than a person armed with photography gear.

    As suspected, my approach and settling in quickly silenced the almost deafening chorus, so I got situated under the blind, leaned against the tree trunk, and waited. And then waited some more. About thirty minutes went by without a sound except for leaves blowing in the wind. And I could still only see one frog in the pool, and even that one was low in the water and partially hidden by a stick. I decided to try to coax a reaction by using my phone to search the web and play a recorded call. I used the Amphibians and Reptiles of North Carolina web site created by Davidson College at http://www.herpsofnc.org/. I played the call twice. No response. I looked through my viewfinder at the one visible frog and played the call again. This time, that frog raised up so that the top half of its body was out of the water. I suppose he was trying to figure out where this caller was hiding. But he did not answer.

    So, I waited some more. Another 15 minutes went by and I was beginning to wonder if I had simply tried to get too close and they were having nothing of it. Then a sound – a partial call. The call of the Upland Chorus Frog sounds something like the noise made by running your fingers over the teeth of a comb – a regularly repeated “crrreek”. This was just one crrreek. But that was enough to stimulate another, then another, and soon the pool sounded like a bunch of busy fingers in a comb factory. Ten or more heads suddenly appeared from the pool and started calling, with the tell-tale enlargement of their vocal pouch keeping time with their crrreeks. The first few callers were partially hidden, either barely out of the water or using some nearby object as cover.

    But, in less than a minute, it was a frog calling cacophony.

  • Salamander Candy

    Spring is here. Maybe not in its totality of warm days and flowering plants, but there are signs – signs of new life. This week I heard the first dawn chorus in my woods – the songs birds sing, especially in spring, at the first light of day. The lilting notes of the Bluebirds are particularly noticeable after having been so quiet for many months. And the first frogs have been heard calling from what should be woodland pools full of water after our wet winter. Sunday was one of the first spring-like days we have had in these parts in quite some time, so it demanded a walk in the woods. My walk ended up along the creek that flows across the power line a half mile or so from the house. In its lifetime, the creek has created several oxbows and pools in the floodplain and these are home to some of my favorite living things, the creatures of vernal pools. These often ephemeral pools are home to a host of amphibians and invertebrates that are found only in waters that contain no fish. One of the most interesting to me is the Spotted Salamander, Ambystoma maculatum.

    Spotted salamander in woodland pool (click photos to enlarge)

    These large woodland salamanders make their way to vernal pools on warm, rainy nights in late winter and early spring, to breed and lay eggs. They are most easily seen by flashlight at night or by gently turning over logs near the edges of the pools. During the breeding frenzy, male salamanders deposit specialized structures, called spermatophores, on the bottom of the pool. At first glance, the spermatophores may look like bird droppings littered about on the leaves in the pool.

    Spermatophores in pool

    But a closer look reveals something quite different. I remember thinking they resembled a gelatinous Hershey’s Kiss the first time I picked one up. These salamander candies are about 6-8 mm tall, with a clear, gelatinous base, and a multi-pronged whitish stalk on top of which is a cap containing the sperm.

    spermatophore 1

    I have watched pools and noticed that usually about two to three days after I first see the spermatophores on the bottom, I find the first egg masses. After the courtship bout, the female salamander picks up the spermatophore in her cloaca and about two nights later starts laying egg masses.

    Spotted laying eggs

    The heavy rain had been on Friday night, but the pool I saw on Sunday contained no eggs and it was getting very shallow, so it started me wondering about the spermatophores. I had always assumed the female picked up the entire gelatinous packet. But I decided to check it out before posting something about this whole process. I quickly turned to an excellent salamander resource on my bookshelf, Salamanders of the United States and Canada, by James. W. Petranka. I had a chance meeting with Dr. Petranka at sunrise this past winter on the viewing platform at Pungo Lake. After observing and discussing the birds for a few minutes, he introduced himself, and I excitedly blurted out, “Oh, you’re the salamander guy”! His book is an amazing compilation of detailed information on the life histories of salamanders and I have referenced it countless times, so it was an honor to meet him in person, and he was gracious to not laugh at my enthusiasm. Petranka referenced the females “picking up sperm caps”. That implies that maybe they do not take in the entire spermatophore. So, I emailed another excellent resource on all things natural history, Jeff Beane, Collection Manager for Herpetology at the NC Museum of Natural Sciences. He responded saying the female squats over the spermatophore and takes up seminal fluid from the top with her cloacal lips, leaving behind most of the gelatinous structure. She may do this with several different spermatophores. And the gelatinous base may remain visible in the water for a few days afterward before decaying. Mystery solved. Yesterday, three days after the presumed breeding bout during the rains of Friday, a few spermatophores were still visible in the pool. These may either not have been utilized by a female salamander, or, they may just be the bases slowly decaying. Later this week, I will check that and other nearby pools to see if there are any egg masses. I always look forward to seeing the “globs of jelly” that result from the nights of salamander candy.

    The story of bird migration is the story of promise – a promise to return.

    ~the movie, Winged Migration

    A week ago, we had a snow storm that crippled much of the south. Today, the temperatures soared into the 70’s. Less than two weeks ago, I stood in awe as thousands of Snow Geese swirled overhead and then landed amongst thousands of Tundra Swans feeding in a field at Pocosin Lakes National Wildlife Refuge. Two days ago, I could only find 8 Snow Geese amidst a flock of a few hundred swans. And even more telling was the view from the observation platform when we arrived.

    Where thousands of white specks had dotted the lake only a couple of weeks ago, there was now not a single one. No duck, goose, or swan could be seen anywhere on the lake. We altered our plans to hike and drove through the refuge looking for birds. A few swans flew overhead, but we only saw two eagles – on my last visit there had been over twenty. The eagles follow the flocks of large birds when they are on the refuge…no eagles, no flocks.

    We drove to Mattamuskeet to see if that refuge was more to their liking. Crossing the lake, we could see a few Canada Geese, but no swans. But the impoundment along Wildlife Drive was full of ducks, more than I had seen in there all winter.

    Most were Northern Pintails, although there were also large numbers of American Wigeon, Northern Shovelers and Blue-winged Teal. A few Tundra Swans were mixed in, but it appears as though most have headed out from here as well.

    Driving through Mattamuskeet, we spotted several Great Egrets, Great Blue Herons, Black-crowned Night Herons, more ducks, a few more swans, and a sizable flock of White Ibis.

    Most were actively feeding, probing the soft mud and shallow waters with their long bills, looking for small fish, or crayfish, worms, and other invertebrates.

    A few were off by themselves and were busy bathing and preening.

    Driving back to Pungo on the way home, we saw a few flocks of swans returning to the lake for the night, but no Snow Geese. Looking back at my notes from the past few months, I found that I had seen the first of the Snow Geese back on November 23. That was a lone bird mixed in with a flock of Tundra Swans, who had started arriving a few weeks earlier. Thousands more arrived soon after, providing myself, and many other visitors, with incredible sights and sounds all winter. Now, in mid-February, most were gone. They are returning to their nesting grounds in northern Canada and Alaska, a few thousand miles from here.

    Another amazing season of wildlife spectacles at Pungo and Mattamuskeet has drawn to a close. And a new season begins. This morning I heard a loud dawn chorus of birds in the woods outside my house. Last night, the calls of Upland Chorus Frogs filled the night air. It is one of the things I love most about this region, the progression of the seasons and the accompanying ebb and flow of life. I’m sure I will find something to keep me occupied until next winter when the first Snow Goose wings its way south and lands at Pungo Lake. Just as the waterfowl are flying north, our spring is moving north and will be here soon, bringing a new burst of life to my woods. Be sure to make some time to get outside in the next few weeks and enjoy its return.

    Several of you have asked about the possibility of buying some of the images you see in this blog. So, I looked around and found a site that offers quality images in a variety of sizes and formats at a reasonable cost. That site is Fine Art America. I really like the fact that they offer image products at a variety of price points and styles from greeting cards to large framed prints. Those of you on my Facebook page have probably been inundated with some posts as I add new images to my gallery at the Fine Art America site, as they link to my FB page each time I upload a new image. But I wanted to make those of you reading the blog aware of this as well. To make sure I liked the quality of their products, I ordered an 11×14 metal print of one of my images and a card of another and was very pleased with the results. They also have a money-back guarantee for your satisfaction.

From there you can go directly to images I have available on my Fine Art America site. If you see something on my blog you would like, but it isn’t on the Fine Art America site, just email me and I can add it in most cases. I occasionally do some heavy cropping of images for posting on the blog if I am trying to emphasize a particular point, and while that amount of cropping often holds up fine for posting in a blog, it may not hold up well for a large print, so that would be the only restriction. Otherwise, I am happy to make any of these images available for purchase.

  • Visit Yellowstone this May

    The geysers and hot springs . . . display an exuberance of color and strange motion and energy admirably calculated to surprise and frighten, charm and shake up the least sensitive out of apathy into newness of life . . . You will be brought to a standstill, hushed and awe-stricken before phenomena wholly new to you.

    ~John Muir, in Yellowstone

  • The Storm

    When snow falls, nature listens. 

    ~Antoinette van Kleeff

    Snowing

    They all said it was going to be a bad storm. And it started right as predicted, and created havoc on the roads in this area unaccustomed to dealing with it. It snowed much of Wednesday afternoon. Thursday dawned gray and cold, and then it started snowing again…heavy. It was the kind of snow that clings to everything – the porch screens, the fence wire, the tree trunks, the branches. The woods didn’t care, and I loved it. There is something magical about a snowfall – the silence, the blanket of beauty spread across the landscape, the way the often hidden or subtle can now become bold against the white backdrop.

    The birds also knew it was coming long before it started. They remained very active at the feeders throughout. During a strong burst of snow, I stood outside and watched as they came and went, cautious at first, and then paying me no mind as they stocked up on seed and suet. Birds the color of the winter woods now can be seen amongst the patterns of snow-covered branches.

    A day later the sun is beating back the whiteness. It will probably stay another day or two, but the snow cannot sustain itself against the onslaught of blue sky and warmth that will be coming this week. This may be its last appearance for this winter. School administrators, road crews, power companies, and many commuters will rejoice. I will anxiously await its return.

  • Trip Report – Pungo

    Last week I had another group going to the Pungo Unit of Pocosin Lakes National Wildlife Refuge. They had been scheduled for the prior week, but the rare coastal snow storm had made it impossible for them to get to Pungo. I headed down the day before to scout the roads that had been so difficult to navigate the weekend before. It is amazing what a dry day can do for road conditions and I was pleased they had improved greatly, although there were still a few pretty difficult mud holes to navigate. A quick drive through in late afternoon and I had the usual thousands of Tundra Swans, Red-winged Blackbirds, 15+ Bald Eagles, and a few bears. The Snow Geese were not in the fields with the swans as they had been last week, but, instead, flew over and back several times, but refused to settle down. They ended up landing briefly in some fields on private land a couple of miles to the north, but as I drove toward them, hunters opened fire, sending the flock scurrying back to the lake for the evening.

    We met at 6:15 the next morning and headed to the refuge. Leaving one car at the maintenance area, we drove to the observation platform on the south shore of Pungo Lake. A chilly north wind greeted us, but relatively few birds compared to previous sunrises. But the Red-winged Blackbirds did not disappoint. Right on schedule, they streamed over us by the thousands, flying in from the east, and continuing on to the fields to our west to feed.

    The morning was relatively quiet. The Snow Geese flew out of the lake at 7:30 a.m., right on schedule, but headed north to places unknown. Swans continued flying out most of the morning as we drove the refuge looking for bears and other wildlife. The reflections in the canals were beautiful, so we stopped a few times for photo ops, but mainly kept looking for some place where wildlife was abundant and active.

    While observing a large group of swans in a flooded corn field, I suddenly spotted some unusual visitors – Sandhill Cranes! Two small groups, totaling five cranes, flew by us out toward private farm fields to the west. While they were a considerable distance from us, there is no mistaking the distinctive flight pattern. I managed a few quick shots of one group before they disappeared. I have only seen Sandhill Cranes here one other time in all the years I have been coming to the refuge.

    Sandhill Cranes
    Sandhill Cranes at Pungo

    The Sandhills were the first of two surprises our group encountered. Later in the afternoon we heard and spotted another Trumpeter Swan as it (or perhaps two) flew by us, mixed in with a few Tundra Swans. I had heard the distinctive call of a Trumpeter while leading another group a week ago, and here was another flying by. When I contacted a friend and USFWS biologist about it after hearing the first Trumpeter last week, she told me they had observed a few last winter while conducting a waterfowl survey in the area and she reminded me they had captured a few several years ago while banding Tundra Swans. She suggested they may be part of the group that was released a few years ago as part of a reintroduction effort in Ohio.

    Part of the afternoon was spent hiking the woods along “Bear Road” and observing the abundant bear sign. We did see a Great Horned Owl and later heard a Screech Owl, but overall, the woods were very quiet and even the lake lacked the usual background sounds of hundreds of swans. They all seemed to be out in the fields feeding, so that’s where we headed for the end of the day.

    After looking at several Bald Eagles overlooking fields full of swans and blackbirds, we finally saw a couple of bears emerge from the trees. But soon, they rushed back in and, to my dismay, I soon saw the reason why – two dogs were patrolling the field and running at  everything in sight. I had seen these same two dogs the day before on a road miles from here on the other side of the refuge, and, later, in this same field. I think they belong to one of the houses along the paved portion of road, but it is unfortunate that they are running loose on the refuge, spooking the few animals that were out on this day.

    With the dogs being in this field, I decided to move up the road to where a few thousand swans were feeding. As we watched and listened, a few hundred Snow Geese flew in…a good sign. Shortly afterward, several thousand Snow Geese came flying in very high up and then began to swirl around the wheat field in their classic group landing.

    Once again, we stood in awe as the sky was filled with thousands of beating wings slowly descending to the fields. Here is a brief video of thousands of Snow Geese settling into the wheat fields, where hundreds of Tundra Swans are already feeding.

    The prime season at Pungo is beginning to wind down, and one day soon, in a week or two, or three, the Snow Geese will all lift off and head north. For days following that, the Tundra Swans will drift off to the north in smaller flocks until, in a few weeks, the lake will be silent once more. Many of the eagles will disperse, with just a few remaining behind all summer. The giant flocks of Red-winged Blackbirds will break up and move to breeding territories to the north. But new species of song birds will arrive, and the bears will start being more active, new cubs will appear, a diversity of reptiles, amphibians and invertebrates will be out and about, and the cycle of life at the refuge will continue. I plan to be there through it all, and hope you can join me.

  • The Long and Short of It

    I admire herons, herons of all sorts. They have a stately posture, epitomize patience, and have bright eyes that can stare down anyone. My recent trip to Florida had lots of heron highlights. Here I report on the long and short of it, Great Blue Herons and Green Herons.

    Standing four feet tall with a wing span of six feet, Great Blue Herons are among our largest birds, even though they weigh in at only 5 or 6 pounds. I was surprised to see them already nesting at Viera Wetlands. In fact, a volunteer said that they were re-nesting, as a recent storm had destroyed several nests that already had eggs. I have seen nesting colonies in NC that were in tall dead trees in swamps, but the ones at Viera were on top of palm trees out in the wetlands.

    The herons were sitting quietly on their nests early in the day, but as the sun got higher, the male flew off and began collecting sticks. He would drop down to a broken branch laying on the ground and inspect it, before twisting off a section and flying back to the nest. Occasionally, a male would go to an unoccupied nest and steal a stick to take back to his mate.

    Once he lands, he presents the stick to the female, and she accepts it (not sure what happens if she doesn’t like a stick).

    She occasionally simply plucked the stick from him without standing up and carefully placed it in the nest. He would then fly off for another. At other times, there was more ceremony involved, with both birds stretching and bill pointing before she accepted the stick. Must have been a really good stick!

    The stick ferry finally ended for the morning and I walked down the border of the wetland dike. Soon I found one of the many diminutive Green Herons I saw on the trip. Green Herons are one of our smallest herons, standing only 18 inches tall with neck outstretched, and have a wing span of 26 inches (about one third that of a Great Blue Heron). They are found in freshwater swamps and marshes throughout the eastern half of the U.S. and up the west coast. Green Herons are richly colored in shades of chestnut, dark glossy green, and streaks of beige and white.

    They have piercing eyes and are slow motion stalkers of fish and other aquatic organisms at the edge of marshy areas and open beds of wetland vegetation. Green Herons are one of the few birds known to use tools to hunt. They have been observed using twigs, feathers, and other objects to create “fishing lures”. They drop the object on the water surface, luring small fish to within striking distance.

    Often, as I prepared to get a shot of one that had momentarily stepped out in the open, it would raise its crest feathers and jump out in pursuit of a nearby Green Heron that had escaped my notice. I’m not sure if these were territorial interactions over food, breeding territory, or both.

    This display was usually accompanied by a neck stretch designed to make this tiny marsh hunter appear bigger.

    Both species are a joy to watch, and I have decided that time spent with herons, short or tall, is time well spent.

  • More than his Belican

    A wonderful bird is the pelican,
    His bill will hold more than his belican,
    He can take in his beak
    Enough food for a week
    But I’m damned if I see how the helican!

    American White Pelicans (Pelecanus erythrorhynchos) are always a treat to see. When I first moved to North Carolina over 30 years ago, the only place I ever saw them was an occasional one out on the Outer Banks. In the past decade or so they have become more predictable in winter at places like Mattamuskeet National Wildlife Refuge. On my recent Florida trip, I had seen a few fly over at Merritt Island NWR but was pleased to find a large flock roosting and feeding on the Click Ponds, part of the water reclamation complex in Viera.

    I spent a couple of hours one day watching them as they flew in and out of the pond, rested, preened, and gracefully fed in their unique fashion. Unlike our more familiar Brown Pelican, which plunges headfirst into waters to capture fish, this species uses a graceful, almost ballet-like motion, to scoop up fish in shallow water. In very shallow water, they turn their head sideways, stretch out their neck with mouth agape, and plunge their bill into the water.

    Here is a very short video clip showing their unique feeding behavior. They will often work cooperatively to herd fish and then plunge their beaks into the water to scoop up a meal.

    And, in fact, a pelican’s bill can hold more than its belly – their large bill pouch can hold about 3 gallons of water, and their stomach only about a gallon! Pelicans have a great deal of control over their pouch – a set of tongue muscles controls movement of the pouch skin, so they can tighten it and expel water after scooping up fish. They can also cool themselves off by gular fluttering, a strange-looking flapping of the pouch skin that functions much like a dog panting. I have seen this on the young of Brown Pelicans in NC on a hot summer day when I helped band them with the Audubon Society over 25 years ago.

    But the most amazing thing I saw these pelicans do with their pouch was what can only be described as pelican pouch yoga – a series of bizarre stretches and gapes. I saw several do this maneuver, one that they can do quickly, so I was only able to capture the sequence on one bird. They start by stretching the pouch over their breast, then stand up and point skyward and snap their bill while having the pouch wide open. Very strange indeed.

    I guess this could be considered a part of their preening routine, something that these pelicans spent considerable time doing while I watched.

    Pelicans kept flying in from a large group in the center of the pond to the group closer to the small area of open water near me, so I was able to watch their graceful wing beats and landing approach with feet down, skidding to a stop as they skated across the surface. With wing spans of 9 feet (second only to the California Condor amongst North American birds), they take up a lot of space as they glide in and take off.

    Having watched these magnificent birds in Yellowstone, I was happy to have a chance to spend an afternoon in close proximity to appreciate their unique adaptations and interesting behaviors. I look forward to my next encounter.
