Hawk or crow?

Observation - Hawk or crow? - UK and Ireland. Description: Audio recording here: http://audioboo.fm/boos/249564 This large, loud bird was sitting 100+ feet up a tall conifer at dusk. I couldn't see it and, from a distance, initially thought the noise was Muntjac deer barking - then discovered it was up a tree!

There were Red Kite in the area but this didn't sound like a Kite to me. Apologies for the wind noise.
