Echolocating animals include some mammals and a few birds; most notably microchiropteran bats and odontocetes ( toothed whales and dolphins ), but also in simpler form in other groups such as shrews, one genus of megachiropteran bats ( " Rousettus " ) and two cave dwelling bird groups, the so-called cave swiftlets in the genus " Aerodramus " ( formerly " Collocalia " ) and the unrelated Oilbird " Steatornis caripensis ".
