David Wood reports a White-thighed Swallow from Brisas de Villa, just next to the Pantanos de Villa on January 9 and 11. This represents the first documented record of this species.
David writes: Attached are a couple of pics taken when the bird landed with B and W Swallows. Not going to win any prizes (and I have made them small files in the interests of send/receive time, but you should be able to expand them), but it clearly shows the size comparison and dark(sooty) underparts and head. You can also make out what seems to be a white thigh patch. In flight the bird was noticeably smaller than B&W Swallow (it always looked tiny, and was easy to pick out on size alone), and more compact in shape. The underparts were uniformly dark (looked brown), and so were the upperparts, with the upperwings and tail a shade darker than the rump. It looked to have a fairly square tail, at least no obvious fork was visible at any time. As I said, I first saw it on the morning of Jan 9th, but only managed flight views, which were rather brief as it hawked insects very actively over my parents-in-law´s garden and the golf course. On the morning of 11th it was present again, doing the same, but I also located it perched on a window of a building under construction, which is when the photos were taken (digiscoped). My guess is that it was roosting somewhere near the house where I was staying, and then dispersing over the pantanos to feed during the day - we did not see it after about 0830 either morning.
