Voice: Loud hissing screech of about 1.5 seconds - similar to barn owl, but with more energy, and dropping in pitch towards the end. There is also a wok-wok-wok call that is believed to be an alarm call.

Hunting & Food: Hunts along forest edges and fence-lines, also hunts in rice fields. Eats small rodents and insects.
