You could try calling the RSPB too?
By the way, If anyone's reading this who finds a young bird that's fallen out of it's nest, you're not supposed to touch it with your hands because the mother will reject it if it smells of human. You're just supposed to leave it alone and the mother will feed it on the ground apparently. Of course cats might be a problem... I only found this out recently so thought I'd share.
Hope birdie's ok!
