Mantanani Scops-Owl

Chunky black-and-white seabird with very thick yellow and red bill. Orange feet. Named for the spikelike protrusion of black skin above the eye. Nonbreeding and immature birds have a darker gray face and duller bill. Nests in colonies on rocky islands or cliffs in Canada and Alaska; winters on open ocean. Only other seabird in range with such a thick bill is Tufted Puffin, which has an entirely black body.

Small, vocal bird of rainforest canopy. Yellow below, dull green above, with light brown-gray head, light peach bill. Sexes alike. Often found with tanagers in mixed species flocks. Frequently heard as it vocalizes throughout the day, a short warbled phrase, recalling Chivi Vireo.

A big, chunky, relatively colorful rainforest greenbul. Mostly olive-green, with a reddish tail and a mostly gray head. The throat feathers are long and often puffed out; they are rich yellow in most of the range, but pale yellow in Nigeria. Found in the understory and at middle levels of rainforest and gallery forest. Usually in small, noisy groups that often join mixed flocks. Similar to Yellow-bearded Greenbul, but larger, with a puffier throat and some gray in the plumage. Similar to Red-tailed Greenbul, but larger, and never shows a pure white throat. Somewhat similar to Icterine Greenbul, but larger, and much darker on the breast and belly. The loud and distinctive call is a rising, two-part “truwa-treeeaa.”
