The male Yellow-rumped Warbler is dull bluish-grey above, streaked with black, and darker breast and flanks. There are prominent yellow patches on the rump, crown, and a small area on the sides. They have a white throat patch in this area. Females and immature birds are streaked grey-brown, but still have a yellow rump and white spots on the tail.

Most are found in mixed and coniferous forests of the Algonquin Highlands. Returning after migration in April, the Yellow-rumped Warbler is one of the first birds to arrive. In the fall, they are the most common Warbler in the Highlands. They migrate in loose flocks, relying on a contact call to keep together. Pleasant trills are heard from this bird, as well as a sharp chek. They build their nest in a conifer, constructed with twigs, rootlets, and grass, lined with hair and feathers. In this nest they will lay 4 to 5 white eggs, spotted with brown.
