Black-necked Stilts are among the most stately of the shorebirds, with long rose-pink legs, a long thin black bill, and elegant black-and-white plumage that make them unmistakable at a glance. They move deliberately when foraging, walking slowly through wetlands in search of tiny aquatic prey. When disturbed, stilts are vociferous, to put it mildly, and their high, yapping calls carry for some distance.
Black-necked stilts sometimes participate in a "popcorn display,” which involves a group of birds gathering around a ground predator and jumping, hopping, or flapping to drive it away from their nests.
