I owned the M50 and traded it for the R50 and have used them both for wildlife with excellent results. As kvbarkley stated the lens will be the defining piece of equipment, buy a good lens. Be aware that the R50 is small and that the setup should be carried and supported by the lens.
Taken with my M50 with a 100-400mm @ f6.3 1/500 ISO 200. you will get as good as if not better images out of the R50 with a good lens! And as a bonus, with a smaller lens it is also a great all day carry setup for street and landscape photography.
