Wilson’s Warbler was first identified by the father of American Ornithology, Alexander Wilson, in 1811. In his honor, the species was placed in a new genus, Wilsonia, in 1838 along with the Canada Warbler (W. canadensis) and the Hooded Warbler (W. citrina). But recent genetic evidence suggests that the genus Wilsonia should be split and merged with Setophaga and Cardellina. Although, considering that the methods used to determine these new relations are six years old, another revision of the Parulid family tree would not be surprising. Wilson’s Warblers are a common resident of moist forests throughout the PNW and perhaps best identified, like all warblers, by their song.
