Even better, older Nikon DSLRs are now cheap with many F-mount lenses being incredibly cheap versus buying new mirrorless gear and lenses.

M43 systems are also excellent for bird watching given the 2x crop factor, and diminutive size of lenses verses larger sensors. Older M43 camera bodies are incredibly cheap versus new equipment. M43 combined with modern LLM-based denoisers means that even low-light photos with higher ISO really can end up looking incredibly good.

No need to go far or spend a lot of money.

I have a Nikon P1000 while it doesn't have the best image quality does make up for it in having a truly remarkable zoom: 24-3000mm. Just the thing for taking pictures of birds and then working out what they actually are at my leisure.
