Based on the head ,beak and tail, I would second the motion that this is a Hawk ... though I am not sure what type.
Exactly what I thought as well, so I consulted with "our" bird expert & this is her reply:

Sorry folks but the poster is correct in his identification. The bird in his photo is indeed a Common Buzzard, Buteo buteo. Note that the poster is from the UK.
When people from the UK settled this country, they saw birds here and named them by appearance which still causes a bit of confusion to many people.
A buzzard by definition is a bird that has a fully feathered head, captures their own prey and rarely eats carrion.
The term "hawk" was applied randomly to many different species of large birds in the New World, including Sharp-shinned Hawks (actually an accipiter) Red-tailed Hawks (actually in the same genus as the Common Buzzard in the photo) and our native harriers and falcons. They were all called hawks even though the accipters were the only true hawks.
What you are all thinking of as being a "buzzard" is actually a New World Vulture and they are not true buzzards. It's a slang term for them only.
New World Vultures, the ones you see flying around overhead in the summer, Turkey Vultures, include in their family condors and are related to storks.
Old World Vultures (like the one in MLady's link) are not related to our vultures at all, but are related to buzzards but are never called that except in old westerns and Bugs Bunny Cartoons.
So, the settlers came over and started naming birds with common names and the names stuck and it's been creating confusion ever since. But if you look at the Latin name then the confusion is cleared up.
The bird in Ron's linked photo is Common Buzzard,
Buteo buteo
And our Red-tailed Hawk is
Buteo jamaicensis
Note the similarities. Hope this helps clears up the confusion.
