The Sunda frogmouth (Batrachostomus cornutus), is a species of frogmouth, typically placed in the family Podargidae of the order Caprimulgiformes. But recent research suggests that the old order Podargiformes should be re-established, wherein like its closest relatives it might be better placed in a distinct family Batrachostomidae. It is found in Brunei, Indonesia, and Malaysia, where it occurs on Borneo and Sumatra. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, and subtropical or tropical moist montane forests.
