I've watched these birds before many times, but they would never come close enough for any decent shots. Thankfully the light was good and they wanted to play ball this day. What a bird?
A great looking male.
As I was watching the Marsh Harriers a small bird of prey put in a fly by appearance. Too small to be a Peregrine, Kestrel was my next thought, but colours weren't quite right. I ruled out Sparrowhawk. What I had in fact seen was a Merlin. The UK's smallest bird of prey and a real bonus for me on a great morning.
