The tawny frogmouth (Podargus strigoides)

The frogmouth family, a group related to the aforementioned potoo, has a wide mouth meant for eating prey, as they're predominantly carnivorous birds that happen to be great at vermin control. For larger prey, the frogmouth may pulverize lizards and rats to make them easier to eat.

They're also known to keep their mouth open and let insects come to them, snapping the mouth shut when a tasty treat comes their way. The tawny frogmouth lives in Australia, blending in seamlessly with local trees.

The general plumage of the Tawny Frogmouth is silver-grey, slightly paler below, streaked and mottled with black and rufous. A second plumage phase also occurs, with birds being russet-red. The eye is yellow in both forms, and the wide, heavy bill is olive-grey to blackish. South-eastern birds are larger than birds from the north. Tawny Frogmouths are nocturnal birds (night birds). During the day, they perch on tree branches, often low down, camouflaged as part of the tree.
