Alligator River National Wildlife Refuge is busy with bright yellow prothonotary warblers (Protonotaria citrea), sometimes called swamp warblers.

Due to land changes throughout their habitat, the overall population is shrinking, states USFWS.

Alligator River National Wildlife Refuge is covered with standing dead trees and prothonotary warblers nest in cavities/hollows found in those trees.

While the birds primarily eat insects such as ants, flies, grasshoppers and spiders, they will also eat seeds, fruit and even the occasional mollusks and snails.
