The most distinctive characteristics of the Blackburnian Warbler are its treetop ecology and the breeding male’s color. One of a large genus of morphologically and ecologically similar warblers, the Blackburnian is the only one with orange in its plumage. The male’s striking black-and-orange pattern makes some observers think of a miniature oriole. Its canopy nesting habits have defied many researchers’ efforts to study its breeding ecology. An estimated 57% of its global population nests in Canada’s Boreal region.
