By December, an array of diving birds that nested at far northern latitudes are wintering on temperate waters across the continent. If we could watch them under water, we'd see this Common Loon racing like a torpedo. A goldeneye dives under water and swims about 10 feet from the surface, while scoters get down to 30 feet in search of clams and mussels. But if one bird stands out as the most beautiful diver, it has to be the Long-tailed Duck. Propelling itself beneath the surface with its wings, it seems to fly through the water, sometimes to depths of more than 60 feet!More info and transcript at BirdNote.org. Want more BirdNote?
