Walk Or Fly?

The forested wetlands of Pocosin Lakes National Wildlife Refuge in North Carolina provide excellent habitat for migratory birds. Large numbers of waterfowl concentrate on this relatively small area in the winter, peaking at well over 100,000 birds gathering in December and January. It is also home to the only population of wild, free roaming red wolves in the world and supports several clusters of endangered red cockaded woodpeckers. Here, a large flock of tundra swans flies over the refuge at sunset. Photo by Ginny P. Gillam. From the US Department of the Interior blog.
