About the pictures I posted a week ago, I only received 3 replies and none really offered "expert opinions". One favored Chuck, another favored Nighthawk, and a third offered no opinion. Is there no one on the list who even knows of a person who could be considered expert at nightjar ID by flight pictures?
As I said this series of pictures appears to show a chuck-wills widow, because of the following three points:
1. Overall shape shows swept-forward wings, very fat head with small bill, apparently eliminating all other birds but nightjars. Can anyone please argue against that?
2. Squared or rounded tail appears to eliminate Nighthawk, which seems to have a notched tail in all pictures and field guides I have seen. Could someone please make a case against that?
3. Sharply pointed wings and wing aspect ratio appear to eliminate Whip-poor-will. Could someone please tell me if that is not correct?
