Wilson's Warbler

Last year I did not catch any Wilson's Warblers.  This year I banded one on 5 May. This warbler breeds across Canada and from Alaska south through the central Rocky Mountains. The species winters from the western Gulf Coast through Central America.

Wilson's Warblers seem, with a couple of exceptions, to be in decline. Recent studies show decreases of about 2% a year.  Exceptions to this trend may exist in logged areas that are currently in secondary growth.  Otherwise, the destruction of riparian habitat and the clearing of forested areas for human development may be contributing this trend (Ammon and Gilbert 1999).
