This is a Common Moorhen, a relative of the American Coot (above). You can see some similarities, but the Moorhen has a brilliant red bill that extends almost to the top of its head. They are found across most of the eastern United States in the summer. They are also found in the marshes of five continents. In Australia they are replaced by a similar, but separate species of Moorhen and, not surprisingly, they don’t inhabit Antarctica at all.
