Matthew has had problems trying to post the picture of the nighjar, so I’ll just append the photo he sent me and his cryptic note:
Here you are. Problem is that it’s not hi res, so when you enlarge it it’s tough to see. I’ve put a pixellated version on left of image. Head is to the left.
The square inset in the upper left is apparently the pixillated nightjar, which is circled in the original photograph. You can make out the head and body if you look hard.
