Here you will find some tips for telling apart the native Pueo or Hawaiian Short-eared Owl (Asio flammeus sandwichensis) from the introduced Barn Owl (Tyto alba). Please read the appearance, sounds, flight and habitat of these two species!

Mottled pale brown underparts with upper breast streaked dark brown.
Mottled pale and dark brown upperparts.
Rounded brown face, yellow eyes and short, often indiscernible ear tufts.

A male’s rarely heard song is a low ‘boo-boo-boo-boo-boo’, whilst females give a ‘ree-yow’ call.
Both nocturnal and diurnal, they can be seen hunting in daylight in suitable habitat.
