Other members of the captive throng that caught the eye included,...
Taiga Bean Goose Anser fabalis, best told from Tundra Bean Goose Anser serrirostris by its friendlier nature (especially when presented with a small brown bag of grain) and the fact it always looks obliquely to the right (the photographer's left) on seeing a camera.
A little pinky. Awwwww, squeeeee.
A gorgeous Redhead. Would love to find one of these amongst the Pochard at Ynysyfro,... albeit p'raps one with the full complement of wings and no rings.
Non-/not quite-captive bird action included a couple of Peregrines and three of the plastic Cranes going over. But it was all about the NAY NAYS(!) and the 'MINGOS(!) really.
