It's a great northern blurred owl. /s ;)

It's really hard to tell without additional information. I would start by grabbing the Merlin app and using the guided search. It will take size, location, habitat, etc. into account and give you a list of things that are most likely. It's free and run by Cornell University so it's safe to use and accurate. It's got a bunch of cool bird ID tools in it if you are into bird identification, so it's neat to have.
