<P> A drey -- or dray -- 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 `` drey nests '' to distinguish them from squirrel `` cavity nests '' ( also termed `` dens '' ) . In temperate regions , dreys become much more visible in the autumn , when leaf - fall reveals new nests built the previous summer or in early fall . </P>
