Bonaparte's Gull Chorus-line

Small, tern-like Bonaparte's Gulls often form a chorus-line at the water's edge. Side by side, in half an inch of water, they stomp their feet as fast as they can. Under this pummeling, a smorgasbord of shrimp is stirred up for the gulls to harvest. Is this a learned behavior, or were these gulls born knowing how to forage cooperatively? Who knows? But it's hard to imagine a more nutritional dance routine! More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.
