Trip Report – a Frozen Mattamuskeet and Pungo

To me, the beautiful and ever-changing patterns formed in lake ice – and in snowflakes, the ice of the sky – are winter’s “bloom,” corresponding to the flowering plants of summer.

I had another trip to North Carolina’s winter wonderland this past weekend. And a wonderland it was…Lake Mattamuskeet was largely frozen, a most unusual sight. The last time this happened was 1986, and, ironically, I was there that winter as well. I met my group on the causeway at sunrise and we marveled at the expanse of grayness before us. A few cold Canada Geese walked on the ice, probably wondering what had happened to their once watery haven.

The marsh impoundments along Wildlife Drive were also frozen, but we soon spotted a Bald Eagle standing on the ice, surveying the scene for a weakened duck or goose that might make an easy kill. A few other eagles patrolled the area, sending hundred of ducks skyward with every pass. Small birds such as kinglets and Yellow-rumped Warblers were busy in the shrub thickets, and American Coot grazed on the vegetation along the banks of the road. But it was a much more quiet drive than normal, save for the loud crunching of my tires on the ice-covered road. Our wildlife highlight for the morning was an otter trying to move across some thin ice, but forced to do a combination of loping and swimming as it frequently broke through the ice on its way to the marsh.

After lunch, we ventured out on the swamp boardwalk across the canal from the lodge. I always take folks on this walk as it is beautiful, quiet, and gives you a view of a habitat that is hidden from most people.

I have photographed this area many times and love the reflections you get in the dark waters beneath the cypress trees, but I have never seen it like this.

As we walked into the swamp, one of the participants excitedly asked about a bird she spotted. I looked out on the ice and was surprised when I saw movement just beneath my feet under the boardwalk. It was a Sora Rail, and only a few feet from us!

The Sora is a quail-sized rail that is more often heard than seen due to its secretive habits. As the small bird strutted out on the ice, I was amazed at its huge feet. We watched it for a few minutes as it foraged amongst the debris surrounding tree trunks and cypress knees protruding from the ice.

The weather started to take a downward turn with heavy clouds and periodic drizzle. Driving along Wildlife Drive, we came across a large flock of Cedar Waxwings feeding on the berries of the invasive Privet shrubs that unfortunately cover the roadsides and thickets on the refuge.

Waxwings are one of our most beautiful birds. They have an air-brushed, silky-smooth appearance, with a bold black mask and yellow (sometimes orange) tail tip. Adults have red, waxy-looking tips to the feathers on their wings.

Weather conditions worsened and the drive back to the hotel was in dense fog. We were on the observation platform at Pungo Lake at “sunrise” the next morning, but it might as well have been a deck in the clouds. It was magical to hear the sounds of thousands of swans and Snow Geese on the lake while not being able to see a single one.

I was worried about road conditions at the Pungo Unit after the unusual heavy snow and it was a worry with merit. Thankfully, refuge staff had repaired two of the large holes in the road I had encountered on my last trip a couple of weeks ago, but the snow melt had worsened other portions of the roads, giving us a few anxious moments as we plowed through the mud and occasional deep ruts. As the fog started to lift, we could see swans flying out to the surrounding fields to feed. Anywhere the birds congregated, they did so under the watchful eyes of predators such as this immature Bald Eagle. We saw over 20 eagles, along with an assortment of other avian predators such as Northern Harriers, Red-tailed and Red-shouldered Hawks, and a Merlin that nabbed one of the thousands of Red-winged Blackbirds feeding in the cornfields.

At one point, we were watching a flock of swans feeding while more swans continually landed to join the flock. We all heard a strange call, which reminded me of a specialty car horn on a clown car in a parade. I had never heard anything quite like it, but it seemed to come from a swan that was landing in the midst of the hundreds of others feeding on the corn. The only thing I could think of was it might have been the call of a Trumpeter Swan. After playing the calls on our phone birding apps that, indeed, was what it sounded like. Even though we desperately searched the flock, looking for the subtle differences in bill shape that distinguish the western species of swan from our Tundra Swan, I could not find it amongst the hundreds of feeding birds. I have written a few experts to see what they think, but it certainly seems we heard a North Carolina rarity. Listen to the call on the web site of The Trumpeter Swan Society here – http://www.trumpeterswansociety.org/swan-voice.html.

Mid-afternoon, we walked through the woods along my favorite spot for locating bears (“Bear Road”). While we saw plenty of bear sign, we did not see any bears, and, to my surprise, no fresh bear tracks in the muddy road. So, I altered my normal routine of ending the day in this usually productive section of the refuge, in favor of heading toward some recently cut over corn fields near the refuge maintenance area. When we arrived at the paved road, we could see thousands of Tundra Swans feeding in the fields. Suddenly, they started filling the skies, much like a slow-motion blast off of a dense flock of Snow Geese. I have never seen this many swans take off at once.

The sun popped out, flooding the field with light, and the source of the swan’s concern soon appeared…a large Black Bear coming into the field from the adjoining woods.

The bear moved quickly into the field, picked up what I thought was an ear of corn, and retreated back to the woods. A closer look at my images (the bear was over a hundred yards from us) showed that it had picked up either a leg bone or wing bone, probably from one of several swan carcasses in the fields.

We saw seven other bears move into the edges of the field over the next thirty minutes as we watched this unbelievable scene of wildlife abundance unfold in the beautiful light of a gorgeous winter sky. Shortly after the large bear disappeared, I looked up and saw what must have been the entire Snow Goose population on the refuge headed our way.

The light continued to get better, turning the geese into golden-winged fliers at times, then bright white ones as they banked. The sky in front of us was soon swirling with thousands of geese noisily making their approach.

We watched as wave after wave started to land. How they manage to pick a spot amongst the hundreds of feeding and squawking geese on the ground is beyond me.

I always try to spot a few Ross’ Geese whenever there are this many Snow Geese close by. We had seen a couple at the edge of feeding flocks, but I enjoy the challenge of identifying them in the sky amongst thousands of their larger cousins.

The grand finale of this unbelievable wildlife spectacle was when, on some unknown cue, the entire flock of 30,000+ Snow Geese lifted off in the classic blast off. The whoosh of their wings as their collectively rise from the fields or lake can be heard for over a mile.

The geese all headed back to the lake for the night, leaving the swans alone to feed (I always imagine they let out a swan sigh when their noisy neighbors depart). It had been an incredible finish to a great weekend, in spite of the challenging weather and roads. I was glad to have shared it with such great folks and happy to introduce the magic of Pungo to another group.
