what is a squirrel's nest called
A drey â or dray â is a nest of a tree squirrel or a flying squirrel. Dreys are usually built of twigs, dry leaves, and grass, and typically assembled in the forks of a tall tree.They are sometimes referred to as âdrey nestsâ to distinguish them from squirrel âcavity nestsâ (also termed âdensâ). drey is almost always at least 20 feet (6.1 m) above the ground, and flying squirrels build much higher. Sometimes squirrels build their own dreys and sometimes they occupy a vacant drey that was previously constructed by another tree squirrel, often of a different species.
