In spring and summer, adult males are an unmistakable, brilliant red with black wings and tails. Females and fall immatures are olive-yellow with darker olive wings and tails. After breeding, adult males molt to female-like plumage, but with black wings and tail. Primarily insectivorous during the summer, Scarlet Tanagers also eat fruit during migration and on the wintering grounds. They spend much of their time skulking among the wide leaves of deciduous trees in the forest canopy, where they are hard to see. They sing a burry, rambling song and give a distinctive, harsh chick-burr call.
