In my opinion the buck in the top picture looks a bit larger. Not only does the rack look bigger, but the body size looks a little larger as well. But who knows maybe because he's a little closer in the first pic, but I still think its 2 different deer.
If you look just above the date. Above the zero in the month there is a red mineral block on the ground. The second picture is several feet forward of where the first is standing. I have looked at the picture close up on my computer. It does appear to me they are two different deer with very simular traits. I surely hope so!!! I hope myself and my son(10yrs old) get a glimpse of one of these if it is two different. I would love to let him take one of them out. While he is on the stand with me he will always get the first shot!!! And he can handle his rifle quite well. Needless to say we will need to see this during daylight hours. Most of my buck pictures are taken at night.
The racks look very similair but I still say that the top deer is bigger and older. I know the picture is taken closer but his body seems to look a little different unless it is just because it is taken at a different angle.
