The Bobolink [Dolichonyx oryzivorus] is symbolic of the prairie and the decline of this wonderful habitat. From their look to their sound (which we feel sounds a little bit like R2-D2), perhaps the most under-appreciated fact is how far these birds migrate.
The Bobolink is an extraordinary migrant, traveling to south of the equator each autumn and making a round-trip of approximately 20,000 kilometers (12,500 mi). One female, known to be at least 9 years old, presumably made this trip annually, a total distance equal to traveling 4.5 times around the earth at the equator! – Cornell Lab of Ornithology’s All About Birds
