BirdNote; American Golden-Plover Lays Claim to the Tundra
Description:
A male American Golden-Plover proclaims its nesting territory with an aerial display known as the "butterfly flight." After flying up 50 feet, the plover switches to slow motion, raising its wings languidly until the wingtips nearly touch over its body, then lowering them gradually until they almost touch below - all the while calling. The plover sustains these slow and exaggerated wing-beats for nearly a minute - hanging in the air like an enormous butterfly.
