From: Birds of Prey - Raptor Bird Calls and Ringtones »

If you hear “who cooks for you, who cooks for you” in the middle of the night in the forest, chances are you are hearing a Barred owl. Opportunistic hunters, Barred owls will prey on rodents, birds and even crayfish – which occasionally gives them pinkish feathers on their chests. Sometimes these owls can be seen wading into the water to capture crayfish. A fairly long lived bird – they can live up to 23 years in captivity – in the wild they generally survive only 10 years. Targeted by humans, they are often shot, and their only natural predator is the Great horned owl.
