Bird of about the size of a crow watching a bird feeding station in our garden.
No interactions present.
I agree that it looks like a male Goshawk. However, I think Syrphus is right, that you would want a better view of the whole bird, to be sure.
Male Goshawk are smaller than females, so your estimation of size would be OK. It does look bulky, as well, though difficult to be certain that it is not just fluffed up. The head pattern looks more Goshawk than Sparrowhawk. The breast stripes, especially high up, are quite broad, and that suggests Sparrowhawk more, perhaps?
I would leave as it is.

Nice to see the experts stumped!
Size of a crow? surely a Gos. That eyestripe says so.
But in a garden?
The experts (I am not one) are not stumped - just going on the available evidence, which is inconclusive. Size of S'hawk and Gos is notoriously difficult to estimate in the field (as with almost everything else). If a crow was sitting in the tree beside it, the opinion might alter, but as it stands we have a picture that simply does not have enough to give a certain ID beyond genus level.
Gardens up here are not necessarily what you might imagine from the word alone. I have had a Hen Harrier hunt through my quite small village garden, and once even a Wildcat. If you look at the location map (satellite view) you will get an idea on the habitat. A Gos would not be impossible by any means.

I remember a friend saying a Buzzard had visited their garden and killed a couple of Thrushes. I never would have believed it until i saw the photos. It actually was a Buzzard so nothings impossible and if you read my original post properly i actually said it probably WAS a Gos.
