Here’s an interesting article about a harlequin duck study in Glacier Park . . .
Warren Hansen, a graduate of Polson High School, has channeled his lifelong love of ducks and the outdoors into a long-term examination of harlequin ducks in Glacier National Park’s McDonald Creek watershed — a renowned hot spot for harlequin breeding activity.
With their signature plumage rivaled only by the beauty of their migratory mountain homes, harlequin ducks have captured the hearts of countless bird watchers and casual observers. The rare birds are sea ducks that typically spend their winters residing in coastal surf zones before migrating inland to nest alongside whitewater mountain streams.
“They’re the only bird to have an east-west migration,” he said.
