Oh no not this question again!!!
Repeat after me - THERE IS NO SINGLE BEST CAMERA.
The "best" camera is the one which suits YOUR needs in the way of facilities etc and the one which suits YOUR budget.
For "wildlife" photography then a Dslr is the best TYPE of camera, there are currently a half a dozen different manufacturers and the best of those (Nikon & Canon) currently have about 20 different models each.
Which would be "best" for you is entirely YOUR choice.
