Yes, it's a Belted Kingfisher. Interesting species, as they've demonstrated evolution of behavior. These are woodpeckers who transitioned to capturing fish. (Like the
Asian bats that also catch fish.)
They're territorial among their own kin-birds, and very wary birds. Since they're hard to approach, closeups are scarce in bird books. It's likely a window strike, and he got his bell rung. Hope he flew off after recovering.
