A crow is a large, intelligent, black bird with a loud call. Farmers and gardeners set up "scarecrows" to keep crows away from their seeds and crops.
A crow is glossy and dark, a close relation of the raven, and a large group of crows is known as a murder. When a crow caws, you can also say it crows — and another way to crow is to call out with satisfaction about something: "I'm so proud of the award I just want to crow about it all day long!" The Old English root of crow is crawe, which imitates the sound a crow makes.
