Comoro Blue Vanga

Small sparrowlike bird found in the Caribbean and northern South America. Males are dull olive above with a variable amount of black on the face and breast. Females are plain grayish-olive overall; note the small size, short tail, and pinkish bill and legs. Very similar to female Sooty Grassquit. Found in pairs or small groups in shrubby or grassy areas and forest edge, typically on or near the ground.

Small, sharp-billed, warbler-like bird. Note yellow patches on the throat and undertail, and bold white spectacles around the eye. Found in all types of forest, and less commonly in scrub, gardens, and plantations. Usually found in hyperactive flocks that can contain dozens of individuals. Often joins mixed flocks of other small birds. Most common call is a high-pitched, rising rattle. Song is a quiet, chatty sequence of “chew” notes. Shows bright yellow patches and white spectacles, unlike any jery. Smaller and more brightly colored than any tetraka. 

A gregarious resident of dense tangles and thickets in otherwise open habitats; not found in dense forest or mangroves. The gray body contrasts sharply with its yellow head, but note that some birds have yellow on the chest as well. Prothonotary Warblers are somewhat similar, but are mostly yellow below with a green (not gray) back. Pine Warblers have a green back, white wingbars, and are usually more extensively yellow below. Song is a series of raspy buzzy notes. Call notes similar to song, but are given singularly or without pattern.
