The Barred Owl can sound like:

• Who cooks for you? Who cooks for you-all?
• or Whoo?
• or Hoo hoo hoo hoo hoo hoo hooooo-ah!
• or like monkeys!
• or you might hear the screech of baby barred owls.

The Great-horned Owl's hoo-hoo-hoo-hoo is softer than the Barred Owl's, and does not have an easy-to-recognize rhythm. Can you hear the two owls calling to each other in the first clip?

• Hoo-hoo-hoo-hoo
• Adults growl when they are alarmed near the nest.
• Babies screech

The Northern Saw-whet Owl may sound like co-co-co-co-co, which some people think sounds like a truck backing up. On migration they make a different note.

• Co-co-co-co-co
• Migration note

The tiny Eastern Screen Owl can:

• whinny
• or trill

The most common bird that says "Whoo, hooooooo" isn't an owl at all. The Mourning Dove is so named because of its call sounds sorrowful, as if it's in mourning:

• Hoo-ah-hoo...Hooo...Hoooo...Hoooooooo
