It is for certain the same buck showing the progression from 2 through 4 years old. I know the face and other unique features of this buck. The change in antler shows how it is hard to identify a buck on that basis year to year. The pictures are not from a camera set-up like a fixed game cam but is a camera that I use while sittingobserving what is there. The big jump can be attributed to perhaps 2 things. The first is that bucks are building bodies in their youth and in their 4th, 5th and 6thyears more "energy" is available for antler, the other is that we were in a severe drought in 2005 and 2006. In 2007 so far we have had 3 times the rain as we had all of 2006. I anticipate that next year all of our bucks will make a big antler jump and I'd love to see this one again at 5 1/2 yo. He is getting harder to photograph each year and of courseI fear that someone on adjacent property might kill him since he is getting pretty nice.
