Is the canon eos 250d good for wildlife?

Yes, with the right lens. The 250D's 1.6 crop turns a 400mm lens into roughly 640mm on full frame, so you get reach without a huge budget. The catch is that the body has no stabilisation, so the lens has to supply it. That makes the lens choice the whole decision.

I'd start with the Canon EF 100-400mm f/4.5-5.6L IS II USM, which frames like 160-640mm and is a sensible all-round wildlife lens. If you want more reach, the Sigma 150-600mm f/5-6.3 DG OS HSM Sports goes to about 960mm equivalent. For a lighter start, the Canon EF 70-300mm f/4-5.6L IS USM is a good first telephoto.

Wildlife is the hardest thing to shoot, so budget for a long lens before a new body. Buying lenses used is an easy way in.
