DNA-DNA hybridisation studies had suggested 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.
The tawny frogmouth was first described in 1801 by the English naturalist John Latham. [4] Its specific epithet is derived from Latin strix 'owl' and oides 'form'. Tawny frogmouths belong to the frogmouth genus Podargus, which includes the two other species of frogmouths found within Australia, the marbled frogmouth and the Papuan frogmouth. [5]

Rostrum (from Latin rostrum, meaning beak) is a term used in anatomy for several kinds of hard, beak-like structures projecting out from the head or mouth of an animal. Despite some visual similarity, many of these are phylogenetically unrelated structures in widely varying species.
The mouth is the body orifice through which many animals ingest food and vocalize. The body cavity immediately behind the mouth opening, known as the oral cavity (or cavum oris in Latin ), [ 2 ] is also the first part of the alimentary canal , which leads to the pharynx and the gullet .
The ground-dwellers are often found under leaf litter within forests, occasionally venturing out at night to hunt. The two main shapes for the microhylids are wide bodies and narrow mouths and normal frog proportions. Those with narrow mouths generally eat termites and ants, and the others have diets typical of most frogs. Egg-laying habits are ...
