Anjouan Scops-Owl

Gray-brown swiftlet with a pale gray rump and a squared-off tail. The westernmost ranging species in the genus and the only member throughout much of its range. Smaller than most other swifts in range except for House Swift, which is black overall with a sharp white rump and throat. Tends to travel in small to medium-sized flocks, often swooping low over bodies of water. Builds dark bowl-shaped nests in closely-clustered colonies under rocky overhangs, in caves, and in old buildings. Gives clicking calls and twitters, especially when near colonies.

A well-marked bulbul with a bushy crest. Olive-green above with a pale yellow throat and extensive white streaks on a dark breast and pale belly. A foothill and submontane specialist found in broadleaf forests, both evergreen and deciduous. Forages in the forest canopy, often in the company of other bulbuls. Somewhat similar to Mountain Bulbul, but has a bushier, more erect crest, darker upperparts, and obvious streaking on the underparts. Generally not very vocal; gives various chirps, warbles, and chips, often strung together into a loose “song” with short, distinct phrases.

Large and chunky with stout dark bill. Nondescript plumage: entirely olive-green with slightly brighter yellowish throat and upper breast. Sexes alike. Compare with female Red-throated Ant-Tanager, which is somewhat more slender and longer-tailed, has a more contrasting pale throat, and paler legs. Found in lowlands and foothills, where small flocks move through lower and middle levels of humid forests. Often in mixed feeding flocks with other species. Occurs from eastern Honduras to extreme northwestern Colombia. Listen for its loud, fast, long-winded song of whistles and chips, along with grating squeaky scold calls.
