Although noted primarily for its waterfowl, Mattamuskeet National Wildlife Refuge also provides habitat for many other species including wading birds, shorebirds, and birds of prey like the osprey and bald eagle. Mammals such as deer, bobcat, otter, black bear, and the endangered red wolf also find refuge here. A variety of amphibians including frogs, toads, and salamanders are common throughout the refuge. The rich diversity of habitats on Mattamuskeet National Wildlife Refuge provides a haven for reptiles including snapping turtles, yellowbelly turtles, eastern fence lizards, and 31 species of snakes. The only venomous snakes are the copperhead, cottonmouth, canebrake rattlesnake, and the Carolina pigmy rattlesnake. The lake, marsh, and woodlands provide habitat for over 240 bird species. Ospreys nest in low cypress trees near the edge of the lake. Hundreds of migratory shorebirds find resting and feeding spots along the edge of the lake and throughout the marsh impoundments. Migrating warblers are popular subjects for bird watchers in the spring and fall.
