Kestrel fighting a buzzard over Streaham Tescos

High in the blue bank holiday sky a Kestrel was fighting a buzzard above Streaham Tescos, during a lovely long walk taking in Streatham Common, Norwood Park, Sydenham Hill Woods, the Horniman Nature Trail and gardens,  Dulwich park and Belair, there were 4 beautiful butterflies, I forget their names, two red types, a Sulphorous yellow and a black one, lots of  nuthatches everywhere, more than I have ever seen before, then at the end the magnificent sight of the russet coloured female kestrel trying to see the buzzard off, it was a perfect, hot April day, Sunny, warm and fresh as bank holidays so rarely are....
