Late summer movement

On my favourite reservoir, Alcollarín, there have been a few passage waders too, feeding along the slowly receding strandline, but the main activity here is the slow build-up of numbers of duck, almost all of them Mallard, deep in their moulting eclipse plumage and a post-breeding concentration of nearly 600 Great Crested Grebes. In late July I was there, a day after hearing that an adult Audouin's Gull had been found at a reservoir in the far south of Extremadura. I checked a group of Black-headed Gulls resting on a spit, and seeing that there was nothing unusual there, started to count the Great Crested Grebes. Once that task was complete, I took another look at the spit where amongst the Black-headed, there was now a larger, grey-brown gull, Looking at it though the telescope, its features confirmed it to be a juvenile Audouin's, my first in Extremadura and a bird which will have orginated from one of the coastal colonies in eatsern Spain. On subsequent visits I saw it or other juvenile Audouin's Gulls (sometimes two were present), part of a small influx of this maritime species into our region this summer.
