Canada Warbler

Male Canada Warblers are among the most beautiful birds. I banded this one last May. These birds breed across most of Canada, southeast into Minnesota, Wisconsin and the northeastern United States, south through the Alleghenies to Georgia. They winter in Northern South America. We saw them in October and November in the Peruvian and Ecuadorian jungles.

Canada Warblers appear to be in trouble. Their population is often declining by more than 2 percent each year. Lumbering and loss of forested wetlands contribute to this problem. A glimmer of hope is that this species can breed, if enough trees remain in fragmented forests. But the warblers’ survival depends on vigilant habitat management (Reitsma et al. 2010).
