Have you herd? Groups of animals often have unique, and sometimes funny, names. You’re probably familiar with the collective nouns for common backyard and barnyard animals, such as flocks of birds and herds of cows. However, there are many more names to discover.

Other names refer to behavioral observations. Check out our alphabetical list of collective nouns to learn where these nouns originated from and how many you know.
