Here is another example of a deer from 3 different years...
To the left is his 6 year old year... to the right is the horrible drought year... and in the middle is this year...
3 very different looking sets of antlers... his frame changes sizes... and his points move around... but look at his G-1's...
they rarely change...
Look at beam shape... that rarely changes...
and most importantly... look at the distinct coloring on his tail... it is red with a black tip...
All of those things put together... and you have yourself a positive ID...
Maybe I should make a post about some of the things I look at to try and identify a deer from year to year...
I would love some pointers other people might be able to throw out there too...
