Brown Sparrowhawk

I haven't seen a sparrow hawk this year and then I see two in as many days. The first was sitting in the road as I rounded a corner driving back from the willow farm and it sat there until the last moment before bursting off into the trees. I am sure it was a sparrowhawk , by the way it flew and acted, but it was darker, a deep brown rather than the familiar grey and stripes. Then on Saturday I disturbed another, 5 miles from the first, but also brown and confident, like a cocky little man in a pub who knows that he can handle himself. Not scared by being disturbed but almost annoyed with me for getting in its way and the pursuit of prey.
