They are commoner than Kestrels at the moment. At 15.40 a Red Kite flew onto the garden list here in Banstead. I even had time to rouse the family to enjoy it as it circled above the house and then drifted westwards. David Campbell was watching another at about the same time over at Canons Farm (maybe a mile and a half away as the kite flies), and a further two went through at Beddington. Whether or not these are genuine continental migrants or wanderers from the re-introduction programmes doesn't really matter - they are stunning to watch.
Garden MV update: only Brindled Pug added to the year list over the past two nights.
