The 'frogmouths' are a group of
nocturnal birds related to the
nightjars. They are found from
India across southern
Asia to
Australia.
They are named for their large flattened hooked bills and huge frog-like gape, which they use to take insects. Their flight is weak.
They rest horizontally on branches during the day, camouflaged by their cryptic plumage. Up to three white eggs are laid in the fork of a branch, and are incubated by the female at night and the male in the day.
The three ''Podargus'' species are large frogmouths restricted to Australia and
New Guinea, and have massive flat broad bills. The ten ''Batrachostomus'' frogmouths are found in tropical Asia. They have smaller, more rounded bills. In April 2007 a new species of frogmouth was described from the
Solomon Islands and placed in a newly established genus, ''Rigidipenna''.
Recent research suggests that the two frogmouth groups may not be as closely related as previously thought, and that the Asian species may be separable as a new family, the Batrachostomidae. Usually placed in the
order Caprimulgiformes, another recent study has cast doubt on the frogmouths' placement within that order,
[1]
and they may be distinct enough to warrant an order of their own, 'Podargiformes', as
Gregory Mathews proposed in
1918.
