Sparrowhawk Tooting Bec Common, Kestrel, Streatham Common

My beautiful Carl Zeiss, cold war era birthday binoculars are a marvel, I've entered a new realm of visions and clearly saw the female sparrowhawk today, later a male kestrel flew very close to me over the car park on Streatham Common, he then flew down the common and met a remote controlled plane, what on Earth must he have made of that? It was the size of a condor!  I forgot to say we saw lots of bats flapping around the trees on the hop farm and also saw the first House Martin of the year. Someone thought the bat was a pipistrelle, but only because they are the commonest, they were too fast to see any identifiable features.
