Indentify please :)

Hi all,

I saw this at Almondell and Calderwood Park today (Livingston, Scotland).

There was a stream, which was near a river, it has woodland to one side and farmland to the other.

These images are blown up, It was larger than a Blackbird, smaller than a Wood Pigeon, but closer to the size of a Wood Pigeon.  I first thought a cuckoo, but the markings are all wrong.

Any ideas?
