Owls make a variety of loud, continuous sounds, including hoots, barks, whistles, coos, and cries. The most common sound associated with owls is hooting, which is deep and soft and used to claim territory and call for mates. However, different owl species have unique sounds. Here are some examples:

• Eastern Screech-Owl: Descending, almost horse-like whinny, used to defend territories.
• Barred Owl: "Who cooks for you? Who cooks for you?".
• Great Horned Owl: The quintessential hooting owl of the United States, with a deep and soft hoot.
• Barn Owl: A bloodcurdling shriek that almost sounds like a classic horror movie scream.
• Snowy Owl: A deep, mellow hoot.
• Burrowing Owl: A simple coo-coooo.
• Tawny Owl: A "ke-wick" or "kewick" sound.
• Eurasian Eagle Owl: A deep, resonant "hoo-hoo".

Owls are nocturnal animals, so the best time to hear them is at dawn and dusk when their active periods briefly overlap with ours.
