Frogmouths: nocturnal birds related to nightjars. Their flat hooked bills & huge frog-like gape help them catch bugs. Weak flyers, they rest horizontally on branches during the day, camouflaged by their cryptic plumage.
The eastern whip-poor-will, is a medium-sized nightjar bird from North America. The whip-poor-will is commonly heard within its range, but less often seen because of its superior camouflage. It is named onomatopoeically after its song.
The male pennant-winged nightjar develops spectacular long white wing streamers during breeding season. This photo of a breeding male was taken along the eastern shore of Lake Tanganyika in the early morning.
