Fallow Deer have extremely good vision and can see even the tiniest details at great distances. They live in a range of climates from cool to humid, as well as warm and dry areas. They can survive in forests, grasslands, woodlands, low mountains, and savanna. As a social species, Fallow Deer roam in groups, which are usually divided into two – males in one group, and females and fawns in the other group. They are primarily active at nighttime, with peak activity times at dusk and at dawn.
