Norfolk Island Gerygone

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.

Large, chunky, dark antbird restricted to northern Colombia and western Venezuela. Male entirely black with namesake blue lores and triangular patch of paler bluish skin behind eye. Female similar but warm dark brown instead of black. Long broad tail often strongly flicked downward and raised back up slowly. Usually seen in pairs, which forage close to the ground within forest. Can be shy and difficult to see. Sometimes follows ant swarms, but frequently seen away from them. Found mainly in the foothills and lower subtropics, up to 1,800 m. Listen for a mourning series of plaintive whistles, “teew, teew, teew, teew.”

A trogon of lowland rainforests, almost always found in the forest interior, away from forest edges. Males and females have distinctive bare yellow facial skin below their eyes and between their eyes and bill. Both sexes have green backs and uppertails, red chests and vents, and finely barred wings. The species often calls motionless in the subcanopy, giving a series of 6-10 sad, descending coo notes, repeating these series 2-3 times per minute. Similar to the larger Narina Trogon, but Bare-cheeked Trogon is told apart by its song, its closed-canopy forest habitat, and the purely green tones on its head, back, and uppertail.
