Saw a lovely family of goldcrests in an old horse chestnut in Aylesbury town centre yesterday - recently fledged young. The song thrushes are very secretive at the moment - I think they have recently-hatched young because I have seen the adults with food in their beaks but can't be sure where the nest is located. Might try and get over to Stockers to see the night heron from the causeway...they tend to be long-stayers (a comment which has probably just put the mockers on it!)
