Once called the Golden Swamp Warbler, the Prothonotary Warbler is the only eastern warbler that nests in tree hollows. Breeds mainly in the southeastern states north to Minnesota, Michigan, and New York. Spends winters in the tropics. Preferred habitats include wooded swamps, flooded bottomland forests, and streams with dead trees.

A group of warblers has many collective nouns, including a “bouquet”, “confusion”, “fall”, and “wrench” of warblers.
