It also is the only one that walks or stands on long thin legs and does not swim. This bird has a varied diet, which includes crustaceans, insects, fish, frogs, and grain that has been left behind. They breed in freshwater marshes and prairies, using grain fields, shallow lakes, and lagoons. Their nest is a mound of vegetation on the ground in a marsh, with a shallow indentation on top for the 1-3 eggs, which are light brown with brown blotches. Hatchlings are born covered with down and are able to walk and swim soon after hatching. They are also able to feed themselves within a day.
