I have seen this one before, perched on the same post between Ponterwyd and Ysbyty Cynfryn. I have not been able to digi-scope it for fear of disturbing the bird as the scope has been in the car boot on both occasions.
It looks pure white when perched and seen front on. In flight the upper wings are grey and paler on the underside.
There are a number of these pale-phase Buzzards in the valley and I have seen them around Cwmrheidol and up at Ystumtuen.
Hywel used to receive reports from visitors of Ospreys and Gyr Falcons and presumably it was the pale Buzzards which had been seen. I knew someone in the valley who was certain there were Ospreys there, even in winter.
