Two in the tree

I was down at the park this afternoon and noticed these 2 fellas making a noise above me. This is my very first attempt at photographing birds - not that it's my style as I mainly do sports. Mind you I don't really have the right lens for it but this was shot with the 70-300mm ED at f10, 1/400, iso 320, sb600 flash.
Anyway, I suprised myself.
Any tips or comments?

Bill
