Tahiti swiftlet

Aerodramus leucophaeus is closely related to the species of the A. Sawtelli. Characteristics include slightly short wings, forked tail, dark brown upperparts, and grey brown underparts. This bird is about 11 cm with a forked tail. They have a dry call with repeated intervals. It has been reported that this species has some form of echolocation. ==Diet and habitat==

The Swiftlet feeds on insects, which it captures while in flight, feeding at high elevations. It prefers wet, rocky and forested valleys at high elevations, and nests either in shallow depressions with overhanging rocks, coastal cliffs or caves. Populations have been found in the Polynesian Island Moorea. They have a wide variety of nest sites: caves, depressions under coastal cliffs or rocks, and are supported using saliva. Nests were found in Marquesas. The climate of the Society Islands is hot and humid between the months of November and April, but cool and dry through the remaining months of the year. The island of Moorea consists of jagged peaks and includes a large mountain range made up of ancient volcanoes. ==Conservation==

Currently this species is not globally threatened. They are classified as vulnerable, but stable. This is due to predation on eggs. They are mostly found in flocks, (up to 100). Total population estimate of 200–500 birds in 1984 and currently still thought to number fewer than 1000 individuals of which the most important subpopulation (100 birds) is in Papehue Valley. ==References==
