The Whitetail Bucks that I have been seeing at the Sequoyah National Wildlife Refuge in Oklahoma have not shed their antlers yet. The past two weeks I have seen nine Bucks and they all had antlers. I did see one small Buck yesterday with only one side but I think that was all he had in the first place. I could see that the other side had not been shed.
The northern regions of the whitetails range experience shedding earlier than the Midwest. They will shed around January. The Midwest bucks tend to keep their antlers on until February, while the southern deer might still be rutting depending on the region, dropping their antlers anywhere from February to late March.
I photographed the below Whitetail Buck yesterday near the Bakers parking area (Bakers Field). He was with another small Buck that I mentioned above that had only one antler.
Here is a post I made four days ago of a couple of Whitetail Bucks in the water: Whitetail Bucks Wading Slough
