The set or group of squirrels is called dray. Dray means the nest of squirrels. Dray is commonly used to describe a mother and her off springs. The other name of the squirrel’s group is scurrying. Squirrels are territorial which means they’ll never allow anybody to enter in their area. They’ll fight to the death just to defend the area where squirrels live. Dray is the name used to refer the squirrel’s family while scurry means the squirrel’s group which does not include a family unit. Many squirrels are not social or you can say solitary animals that mean they avoid gathering or travelling in a social group.
