The Southern Rough-winged Swallow is a small bird, mostly brown color in the upper parts and grey to white on the underparts; it shows a light orange patch on the throat. They are frequently seen, both flying and perched in lowlands in Costa Rica. They are able to catch insects in mid air, during acrobatic performances. The Northern Rough-winged Swallow is very similar, however that species lacks the orange throat of the Southern.
March 2nd, 2017 was a lucky day. I saw some Jacanas foraging in a small creek, so I thought I could bring my camera and try to get a nice shot. When I returned, I saw this speceis instead, which I had not seen before. It was late in the afternoon, so there was not much light to work with. The weird feathers on the top of the head were intriguing. Then on a trip to look for the Three-wattled Bellbird, we were lucky to find a group of about 5 individuals. They had at least one nest, as one individual would rest on the ground from time to time, while the others displayed aggressively towards us.
