Herd of red deer does (Cervus elaphus). A jackdaw (Corvus monedula) is feeding on ticks from the ear of one of the does. These deer occupy upland areas of much of Europe, northwest Asia and northwest Africa. Groups of does congregate together in herds. During autumn, stags follow the herds and compete for the attention of hinds. Red deer mating rituals are known at the rut. Photographed in October.
