If you are investing in a new DSLR and are serious about wildlife photography, here is a good camera. I recommend it due to the good reviews earned and the weather proofing, while I rest the details to Ken Rockwell. Weather proofing is important. Without it your camera is a white elephant in the bush!
I personally prefer the D7100 due to the attractive price for what you get for a top of the line DX!
