Key behaviours / activities to look out for this month are:
Continued, moderate reduction in roe deer activity.
Mothers keep fawns in close attendance.
Towards the end of the month (and early into December) adult bucks shed their antlers.
As winter approaches, the food supplies start to run down, and the fawns need the adroit guidance of their mother to secure resources.
Autumn storms strip the trees of their leaves, which they are a favourite of the deer, particularly ash leaves.
The males continue to keep a lower profile than they did in the spring and through the summer. When they do move about, you can photograph them as they move along well used deer paths, which often pass through bush lines.
They have favourite spots where they like to lay up; quiet areas, which are out the wind are preferred, especially if they can warm themselves up in the sunshine.
The bucks' testosterone levels fall sharply after the summer rut, with the oldest bucks' hormone levels declining prior to the less mature males. And as a result of that, the decalcification which occurs at base of the antlers is more advanced in late autumn than it is in younger males, hence the older deer are normally the first to shed their antlers.
If you get to know the home range of a certain buck, you can search his domain, and possibly find his jettisoned heargear. This antler is the left-hand spike from the mature male shown above. The antlers normally fall off when the buck shakes his head, or when he lands on the ground, when crossing a fence line, etc...
