A very small songbird with a yellow stripe on the head. Adults are olive-gray on the upperparts with white underparts, with thin bills and short tails. They have white wing bars, a black stripe through the eyes and a yellow crown surrounded by black. The adult male has an orange patch in the middle of the yellow crown. The juvenile is similar to the adult, but with a browner back and without the yellow crown.
They forage actively in trees or shrubs and their breeding habitat is coniferous forests.
