Sunday 31 July, sunny, hot, variable E-SE wind: More Black Kite migration with 180 passing North-South directly over Gaucin between 1600-1605 and another 45 at 1630. These birds were very high, most not visible to the naked eye, and some only just visible with 10x binoculars. Interestingly there also appeared to be a large passage of Swifts along the same route, albeit at a slightly lower altitude. Also an Alpine Swift over Camino de Avedin - they seem to be everywhere at the moment. A flock of 50 European Bee-eater flew over the village at 1830.
