Bobolink (Dolichonyx oryzivorus)
Fluttering over meadows and hayfields in summer, the male Bobolink delivers a bubbling, tinkling song which, loosely interpreted, gives the species its name. The male is unmistakable in spring finery, but before fall migration he molts into a striped brown appearance like that of the female. Bobolinks in this plumage were once known as "ricebirds" in the South, where they occasionally used to cause serious damage in the ricefields.
