Most of the following images are of two Sparrowhawks that frequented my garden. Attracted by the birds at the feeders they made daily forays through. I have even been in the garden sitting quietly when one swooped right over my shoulder.
On an occasion a few years ago one hit our window and knocked itself out. We put it in a dark box overnight and took it to a rescue centre next morning. It was fine, we took it home and released it.
