Saturday 11 August, partly cloudy am, hazy sunshine pm, light W-SW wind, 41C: Officially the hottest day of the summer (so far) reaching a shade temperature of 41.4C at 1500hrs. My first returning Honey Buzzard this morning with 4 flying around the Loma de Avedin area at 1000hrs; interestingly they were quite vocal which, according to 'Collins Guide', is unusual outside of the breeding season. Also seen were a female Sparrowhawk, Common Kestrel and Short-toed Eagle. There was also a Red-rumped Swallow around but it didn't seem to have any interest in the 'abandoned' nest. Despite several forays onto the heat of the terrace during the afternoon all I saw were a few Griffon Vulture, a 'local' Short-toed Eagle, House Martin and Barn Swallow.
