Whistler's Warbler

A very large storm-petrel with large broad wings and a long forked tail. White rump and throat patch are often strikingly obvious, even with brief views. Pelagic, but occurs in groups near colonies. Combination of stark black-and-white plumage, relatively large size, white throat patch, and long gliding flight with periodic surface bounces is diagnostic. Silent at sea.

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."

Medium-sized, slim shrike patterned in dark gray, black, and white. The male has completely white underparts, while the female has a rufous flank patch. There are large white slashes across the shoulders. Found along forest edge and in forest clearings, lush woodland, cultivations, and gardens. Usually seen singly or in pairs. The song is a slow, highly varied series of many different types of notes, and can include imitations of other birds. Similar to Northern Fiscal, but has a gray crown and back. Distinguished from other black-masked, gray-backed shrikes by the lack of a white nick on the wing.
