OK James,

Here' s the buck from your other picture. I put it through the same rigamaroll to see what the antlers would turn out like. Granted the picutre is much clearer, but the end result is that the camera is able to distinguish mass from air. Thus the other picture is very likely a doe because there is no distinguishable mass.

Again, I say the apparent tines on the first pic are likely just colour deviations.

Cheers.
