This isn't a very good photo, but the Sparrowhawk doesn't always pose for its photo like some birds. It was soaring very high above the links. The female is all over brown, with bright yellow eyes. The male is more blue/grey in colour with a pale pink streaked front. His eyes are a deeper yellow. I often see a sparrowhawk flying quickly through the trees, or sometimes a large flock of birds fly up, with a sparrowhawk following.
