A group of squirrels is called a scurry, which is the most commonly used term for a group or gathering of squirrels. The word "scurry" is a loanword from the Old English word "scurra," which means "feral; wild". Another term used to describe a group of squirrels is "dray," which is mainly used to describe a family of squirrels. The term "dray" derives from the alternate spelling of the word "drey," which is a term for the squirrels nest. Dreys are usually built from twigs, dry leaves, and grass and tend to be assembled in the forks of a tall tree.
