‘Little backpacks:’ GPS used to track nighthawks from northern Alberta to Brazil
EDMONTON — The whoosh of nighthawk wings is a familiar sound in the Canadian dusk.
Now, scientists have figured out where those enigmatic wings whoosh off to for the winter.
“We have identified where these birds actually go,” said University of Alberta biologist Elly Knight, co-author of a new paper in the Canadian Journal of Zoology.
Nighthawks breed almost everywhere in southern Canada and as far north as central Yukon.
