I think it's a young merlin, not yet fully fledged. You can see down and immature feathers on the legs and breast. One site said they nest on the ground so it may have gone walk-about on a dewy morning! On the other hand it may be an adult molting and we're getting a peek at its unders - the wing feathers don't look long enough, either.
