Western Bristlebird

Typically dull mid-sized greenbul with a long bill and tail. There is geographical variation, with the western birds more yellowish below, and the eastern birds more whitish. Usually shows a distinctive pale eye-ring. Found in the thick undergrowth and mid-story of forest at middle and high elevations, usually in small groups. The call starts with slow and chatty notes, then accelerates into a grating, up-and-down series. Somewhat similar to Gray-olive Greenbul, but larger, with a darker bill and legs and usually some yellowish tones on the underparts. Similar to brownbuls, but more olive-green on the back and yellowish below.

Tiny bird with a strong thick bill and a short tail. Males are mostly glossy dark greenish-blue with a yellow band on the forehead and are entirely yellow below. Females are olive-green above with gray sides to the head and on the center of the breast and belly with yellow flanks. Inhabits the canopy of humid forests and forests edges; often accompanying mixed-species flocks. The song is a fast series of squeaky notes.

Found only on Raso Island of the Cape Verdes. Overall grayish-brown and moderately streaked including the breast. Note the large and heavy bill. Sometimes erects small crest. Belongs to the same genus as Eurasian Skylark, but is smaller with shorter wings and tail than Eurasian Skylark. Found along dry riverbeds on flat plains. Song is similar to that of Crested Lark. Call a short rattle, "Chureep."
