Sunday 30 October, mostly sunny, light E wind: Another lovely day - warm enough to eat both breakfast and evening meal outside! A bit quiet on the bird front, though. This morning we walked from 'Estacion Cortes', more or less following the Rio Guadiaro towards El Colmenar, to El Puente de los Alemanes; this tranlates to 'The Bridge of the Germans' only it isn't a bridge, it's an aqueduct built to carry water to the hydro-electric power plant at El Colmenar, and it was actually built by Belgians! Along the way we saw lots of Black Redstart, including 4 plus 2 Stonechat in one small tree, 40+ Griffon Vulture, Common Kestrel, Green Woodpecker, Song Thrush, Grey Wagtail, Kingfisher, Sardinian Warbler, 3 Woodlark, 2 Crested Lark, Chiffchaff, Blackcap, small flocks of Chaffinch, Goldfinch and Pied wagtail.
