Moustached Treeswift
Hemiprocne mystacea
An enormous, long-tailed swift of lowland and foothill forest edge. In flight, long, thin wings with a white line behind the black trailing edge, and a long, forked tail usually held to a point. When perched in trees, shows 2 white plumes along the face, and males have a rusty ear-patch between. Often seen flying at dawn and dusk. The only treeswift in its range and no other swift comes close to the size or tail length. A sharp “kwik! kwik! kwik” or downward, raptorlike “kweeuu!”.
