Is the canon ef 70 300mm f 4 5 6 is usm good for wildlife?

Yes, it's a sensible first telephoto for wildlife. It's stabilised and autofocuses, and 70-300mm gives you the reach you need for animals that won't come close. The trade-off is the aperture. It starts at f/4 and drops to f/5.6 as you zoom in, so you'll want good light or a higher ISO at the long end.

On a Canon APS-C body, it frames like 112-480mm on full frame, which gives you even more distance. It also behaves like about f/6.4-9 for depth of field, so more of a subject stays sharp.

The site also lists a II USM and an L IS USM version of this lens, so compare those alongside it. Read wildlife and sport for what to expect, and since buying used makes trying a long lens cheap, a used copy is a good way to test it.
