The Prothonotary Warbler (*Protonotaria citrea*) is a small, strikingly beautiful songbird native to North America, renowned for its brilliant golden-yellow plumage on the head and underparts, which contrasts vividly with its blue-gray wings and tail. The male is especially vivid, with a large, dark eye that stands out against its bright face, while the female is slightly duller in coloration. It is the only eastern warbler that nests in natural tree cavities or nest boxes, making it unique among its family. This species favors wooded swamps, bottomland forests, and areas near slow-moving water, where it forages low among the vegetation for insects and small invertebrates. Its song is a distinctive, loud, and ringing series of "zweet zweet zweet" notes, easily recognized in its wetland habitat. A neotropical migrant, the Prothonotary Warbler breeds in the eastern United States and winters in Central and South America and the Caribbean. It is considered a species of conservation concern due to habitat loss in both its breeding and wintering grounds.
