What animal can stay awake the longest?

The animal that can stay awake the longest is often cited as the Pectoral Sandpiper, with males going nearly two weeks without significant sleep to maximize mating opportunities, taking short, deep naps; however, birds like Great Frigatebirds and Alpine Swifts can sleep while flying using unihemispheric sleep (one brain hemisphere at a time) for weeks or months at a time, truly minimizing total downtime.

Do birds sleep while flying?
