Robert Cleland pointed out to me in a note that in the book "The
Wandering Albatross" by Robert Cushman Murphy, the author says that
one bird stayed with his aircraft carrier for over two days as it
steamed upwind. He concluded that albatroses can and do stay flying
all night. I now recall having read this about albatrosses, so they
are another bird like swifts and frigatebirds that treat night as
day. I wouldn't be surprised if numerous other seabirds do the same,
actually, as I know that Black Skimmers feed at night, and I've seen
gulls flying around at night. My statement was right out of the
frigatebird paper, and I should have thought more critically. The
authors of that paper probably hadn't attempted to find out about all
the other bird groups.

Happy night flying,
Dennis
