Wilson's Warbler, Cardellina pusilla, is a New World warbler that breeds in western and northern North America and spends the nonbreeding season in Middle America. It is a small passerine with a green-brown upperpart and yellow underparts, and the male shows a black cap. The western race is greener above and more vivid than the eastern form. Its breeding grounds are open woodland with shrubs and thickets in damp places, while in other seasons it uses secondary growth and a range of wooded and brushy habitats.
