My trail cam picked up some interesting footage last week.

It showed a male roe deer rubbing his head on a branch and then just over 24 hours later a fallow buck rubs his head on the branch next to it (at first I thought it was the same branch). Is this behaviour scratching an itch, scent marking, rubbing new antlers emerging (the fallow deer particularly looks like it has new antlers) or just a tree with convenient branches at the right height for them to rub against? Any ideas.

p.s. does anyone have any ideas why one snippet is very over exposed and the other isn’t. The bushnell camera was set the same for both (LED control = medium and Sensor = auto) and it is a similar time of day. I think maybe it wasn’t quite dark on the first one and then definitely dark on the second.
