Very good first guess M.E., but Hugo is more or less there. It is looking across the Afon Glaslyn from the footpath on the eastern side of the river. I've never seen it before, but of course you have to be there in the spring and it doesn't show up on Google Earth! A very good guess at the osprey chicks at Pont Croesor by both, but the "follically-challenged bird of prey" I was referring to was Moel Hebog, (literal Cymraeg translation = "Bald or bare hawk or kestrel!), on the lower slopes of which the floral ring is situated. (See pics).
Mrs Gwynant and I had a trip out to Beddgelert on the WHR, walked the Fisherman's Path and returned on the bus to Caernarfon, the visibility was superb and Snowdon and the Nantlle Ridge were crystal clear.
