Canada Warbler

Canada Warblers are late spring migrants and pass through our area early in the fall. They are faithful mates, with some individuals remaining paired for up to six years (Reitsma et al. 2010). Populations of Canada Warblers are declining about 2% a year—breeding birds suffer from loss of forest wetlands and  the secondary habitat they prefer. Canada Warblers winter along the east slope of the Andes, which are being deforested. I banded this male in late May 2014 in Northfield, Minnesota.
