The Ergo Loon Call features the 'Hoot' - it lets other loons know that it's in the area and helps maintain contact with others in a family group. 'Wail' helps one loon maintain contact with another. It's used to locate a mate or a chick. 'Yodel' is used only by males. This call helps establish borders and is used to comfort others, like a vocal signature. 'Tremolo' is the only call loons make while flying and is made by both the males and females.
