Two more Kites today!

I saw one moulting kite at a farm near St Nicholas today at about 10 am  and another on the road near Dinas Cross at about 3pm. I also see Ruth  had ten over Dinas Cross at midday.
This is nothing less than a phenomenon, where are they all coming from, are they all Greg's birds dispersing or is this a wave of even more birds ?
When I first came here in the late 70's there were only about 30 odd known pairs breeding in Wales . In the 80's & 90's when I used to camp out in the mountains with the Tregaron Community Kite Watch, intent on stopping nests being raided, the number was still just over a hundred or so.
Those being seen moving through here now, must be non breeding birds on some kind of movement (if they are British?), therefore, either too young or inexperienced to hold a breeding territory or failed breeders. Why are they ending up here?
If it is the case that they are Welsh Kites, massive acknowledgement should be given to people like Peter and John Davies, Iolo Williams and Kev Tyrell not to mention the lady whose name I forget who first started the feeding station near Tregaron. If not for their efforts this would not be happening. Why they are here now is something of a mystery but as one who spent time with many other volunteers trying to stop the deviants whose obnoxious hobby of egg collecting almost wiped the Red Kite off our breeding bird list, it is a very happy period of time!
