This is the strangest nightjar I have ever seen - or rather, was able to discover, after the local guide actually pointed it out. It was down in a tree crevice, probably sitting on eggs, and was almost completely camouflaged. I have now cropped the image so that it is more visible, with the little beak on the left and the tail on the right. The "red neck" (which has given it its Swedish name) is visible in the picture as a reddish-brown, downy area just behind the flat head. The species seems to lack a sound, which is very unusual among nightjars.
