Edit: the 5D Mark II is not a wildlife camera. Its focusing system is not designed for fast action (although, it can be done). Its primary function is for studio and landscape work.
The 7D has a better focusing system and a ridiculous burst rate, coupled with the 1.6x reach, which is better-suited for animal photography.
The right tool in the professional Canon domain for wildlife and action (as well as 1.3x reach, being an APS-H system) is the 1D Mark IV.
