Black-and-yellow phainoptila (female)

The Black-and-yellow Phainoptila is a small bird with distinctive yellow flanks. They can look much bigger because they hold air within their feathers. Males have a black back, head and tail, yellow flanks and rump, olive breasts and grey bellies. Females have a black cap, olive breast, rump, wings and tail, yellow flanks, and grey throat, nape, and belly. Young are similar to adult female, but duller and with no grey on nape and dusky streaking on breast.
