This is BirdNote!
Washington Irving called the Bobolink “the happiest bird of our spring.” “His life seems all song and sunshine.” Emily Dickinson called the Bobolink “the rowdy of the meadow” for its bubbly, jangling song.
Bobolinks return to North America from the tropics each spring, having completed one of the longest migrations of any songbird in the Americas: roughly 6,000 miles.
Bobolinks fly all the way from northern Argentina to the northern states and Canada. They cross all sorts of hazardous terrain and hundreds of miles of open water.
How do they accomplish this prodigious feat?
Bobolinks, like many birds, rely on cues from the stars and sun and landmarks on the earth to guide them. But they also have an ace up their sleeve. Bobolinks can sense the earth’s magnetic field. Their nasal tissues contain minute quantities of the mineral magnetite, providing the birds a kind of built-in compass.
Farmers who delay mowing their hayfields until mid-summer or later – after the young Bobolinks have fledged – help assure the future of these amazing birds. And the Bobolinks help the farmers by eating destructive insects and the seeds of weeds.
