The American avocet has an elegant, delicate appearance that extends all the way to its long, amazingly thin, and slightly up-curved bill. It swishes its bill from side to side through shallow water, looking for crustaceans and insects. Though it looks too delicate to be believed, the bird uses its bill for feeding and will aggressively attack predators like Northern harriers and ravens.
