Like Henning and Dan Theman, I thought it 'didn't look quite right' for a Common Buzzard, and thought it might be a stock photo off the internet with a RTH mislabelled as CB - though unlike Gwynn, I wasn't able to find the pic elsewhere even with google image search.
If it is indeed in Winsford / Weaver Parkway, then yes, it should be a Buzzard: but there are also a number of escaped falconers' RTH floating around the country, so that still can't be completely excluded.
Anyone know of any reliable ID characters to distinguish RTH from CB, particularly in immature plumage when RTH doesn't have a red tail?
