Blackburnian Warblers stand out among warblers for their bright orange and black breeding colors. In fact, they are the only warbler to bear orange coloring on their throats, making them relatively easy to distinguish from the American Redstart— the only other warbler with orange and black plumage.
Genetic analysis reveals that the Blackburnian Warbler is most closely related to theBay-breasted Warbler. The two species overlap throughout much of their range, share approximately 97 percent of their genetic information, and may occasionally hybridize.
