In addition, each wing is around 27–34 cm long.The usual crow sound is a quick "caah-caah-caah." During this, the bird often appears to dance. American Crows are known to speak a wide range of sounds – sometimes even mimicking other animals. Though predatory birds themselves, crows still have predators such as owls and hawks.
