A family of owls with typical behaviour: nocturnal, silent flight and highly camouflaged, all of which makes them particularly difficult to spot. Listen out for the distinctive growling call instead.

- The crown, facial disc, and upper breast are deep chocolate-brown.
- Forehead, eyebrows and most of the ear-tufts are white.

- Tail feathers are chocolate-brown with very fine darker mottling.

- The call is a deep, rolling growl repeated regularly.
