What bird is this in the wood?

Hi,

Saw this bird on Thursday in a small wood surrounded by urban area. I am in Kent. It was bigger than a blackbird; I'd say jackdaw-sized? It was also a bit redder in real life than it seems to be in the pictures. I think the yellow bits to its head in the second pic are just from the sun. 

Sorry the pictures aren't better, but you can see its two-tone plumage. I am honestly flummoxed what it could be.
