Imagine carrying heavy battery-operated equipment - along with all your camping gear - across the tundra. That's what recordist Gerrit Vyn did on assignment for Cornell's Lab of Ornithology.
His mission? To record the calls of this Yellow-billed Loon. You can learn more about the lab and about The Macaulay Library of Natural Sounds - see Related Resources below.
BirdNote is grateful to all the radio stations that carry the show. And thanks, too, to recordists, photographers, donors, and especially the listeners!
