Amazing sounds. Male fallow deer make short, low-pitched groaning noises (bolving) to challenge other males and to impress the females. When these calls are analysed, it’s been found that each buck has a distinctive voice and an individual pattern of groans. The doe is the most vocal of the sexes and she will communicate with her fawn and other members of the doe group with a variety of squeaks and bleats. :) | The Forest of Dean Picture Book
