Sparrowhawk wiggling on the nest, others hear and see first cuckoo

I saw the Sparrowhawk wiggling on the nest today, others heard and saw the first cuckoo on Tooting Bec Common in 25 years - in the Bedford wood! I realise how lucky I was to hear a cuckoo last year in Sydenham Hill woods and the year or so before in Norwood Grove, hope I hear and see one this year. It was a moody day today though I escaped a soaking...

 These two images of Bedford Wood were taken seconds apart.
