Whilst in the USA last year Oregon to be more precise, I got a life tick in the shape of a Common Nighthawk, in direct sunlight late afternoon flying over a belt of pines.
It occurred to me that Nighthawks unlike Nightjars can not infrequently be seen during the day sometimes over fresh water where it has been noted that they can flock particularly before migration Aug/Sep.
I have to assume that this behaviour has not ever been recorded in the Old World for Eurasian Nightjars, thus am wondering what might drive this behavioural difference?
Cheers
