Bird ID - no picture sorry

Hello,

Terribly sorry I wasn’t fast enough to catch a picture and I don’t know too much about birds, I just saw one that I’d love for someone to tell me what type it might be.

I’m in the south west of the UK, and a fairly small, maybe robin sized bird came up to my window and almost hovered there for a few seconds before flying off. It wasn’t very colourful although I didn’t get the best view of it.

I appreciate it might be a very obvious answer, but I’d be very happy for someone to tell me what birds in the UK can hover like that!

thanks :)
