Identification Tips

When identifying the White-lined Tanager, look for the male's striking black plumage with white accents on the wings, which can be seen as he takes to the air. The female is distinguishable by her uniform rufous coloration, which sets her apart from the male.

Habitat

Breeding

During courtship, the male White-lined Tanager engages in a display of his underwing white spots, opening and closing his wings in front of the female.

On average, the species raises two broods per season.
