I've been shooting over the same piece of ground for several years now and take a few bucks there most summers.
Most of the bucks I've shot have antlers that are medium to light brown in colour.
This year I've noticed that the four bucks I've taken have very dark antler colouration and others I've seen also have darker antlers than what I would call usual for my patch and the dark colour is all over the antler, even the tips which would normally be slightly lighter.
There is no fir, the woodlands are oak and other broadleaf species and have been the same for hundreds of years.
Is this purely coincidence or had anyone else noticed similar?
Are plants producing more tannin this year?
