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.

Ohhhhh, there it is! That was not one of the 3 spots I picked, but you can see it quite clearly if you look at the original picture and use this one as a guide.
I still can’t see it, but then there is no such species as a pixillated nightjar.
At least I can see this one once the circle is drawn around it, unlike the last one.
I am proud to say I spotted the nightjar. Makes up for the utter failure with the moth.
Full resolution images would be much appreciated.
Dang…these things are experts at camouflage!
Sheesh…I looked for it for about 5 minutes this morning and never found it. I just showed the original picture to my wife and she found it in 5 seconds.
