Roe Deer in the grass

In the springtime we often spot Roe deer in the long grass in this field during early morning, usually two but this morning three, a male and two females.
Roe deer usually live in woodland. They also venture into fields to graze young tender grass and apparently prefer "clean" grass, freshly washed by rain or in fields without livestock.
This field has been left to grow for silage by the farmer and the grass is now quite long making the deer better camouflaged.
