wilson’s warbler
A common warbler of willow thickets in the West and across Canada, the Wilson’s Warbler is easily identified by its yellow underparts and black cap.
Cool Facts
1. The Wilson’s Warbler is found in a large diversity of environments in the winter. It is the only migrant warbler regularly found in tropical high plains (paramo).
2. The Wilson’s Warbler trends toward brighter, richer coloration from the eastern part of the range to the west. The Pacific coast populations have the brightest yellow, even orangish, foreheads and faces. Western-central and Alaskan birds are slightly larger than the eastern and Pacific coast populations.
