I called him 4 yrs old in 2015, 5 in '16 and 6 this year.
Low fence, native deer on LF 900ac. bordering 8,500 low fence acres. Free-choice protein available Jan-Sept. on both ranches, in good years. Year round during drought. The fence in the background of first photo is neighbors to our north.
First impression from the first 2 photos above in 2015 was a 5 yr old. Pretty sure that was correct, but convinced myself he was only 4.
Accurate aging, from photos only, is a crap shoot. At best. Never seen this deer in person.
So how old is he? I truly have no idea as these are the only progressive history photos we have of him.
