bobolink

(bŏb`əlĭngk'), common name in the N United States and Canada for an American songbird, Dolichonyx oryzivorus, related to the blackbird and the oriole, belonging to the family Icteridae. In spring the plumage of the male is black except for the white shoulders and lower back and the buff nape. After the breeding season the male assumes yellowish, brown-streaked plumage like that of the female, and his former voluble singing is reduced to a single call note. Bobolinks winter in South America; in Jamaica they are called butter birds. In the north they are insectivorous, but they may feed on rice crops during migration in the south. They have been known to gorge themselves in the eastern wild rice marshes and in cultivated fields in South Carolina and Georgia, becoming so fat that they used to be hunted as game birds. Because of these feeding habits they did serious damage to crops as they migrated, and they were called rice birds or reed birds. Bobolinks are now a protected species and are no longer hunted. Cup-shaped nests are built by the female in grassy fields. Polygamy occurs, but monogamy is more common. Bobolinks are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

For the bobolink, we found that the key vegetation characteristics correlated with breeding pair density were the absence of both trees and dead vegetation.
Other species widely held in early American homes included Baltimore orioles (Icterus galbula), bobolinks (Dolichonyx oryzivorus), rose-breasted grosbeaks (Pheucticus ludovicianus), eastern bluebirds (Sialia sialis), indigo buntings (Passerina cyanea), gray catbirds (Dumetella carolinensis), purple finches (Carpodacus purpureus), "black caps" or black-capped chickadees (Poecile atricapilla), and red-winged blackbirds (Agelaius phoeniceus).
The Partners in Flight (PIF) Bird Conservation Plan for the Dissected Till Plains (Fitzgerald and Pashley 2000), a region that encompasses both the Sandstone Prairies BUL and the Southeast Prairies BUL, identifies four additional priority grassland bird species that we detected in our study; dickcissel, field sparrow, and grasshopper sparrow were detected at many study sites in both the Sandstone Prairies BUL and the Southeast Prairies BUL, while bobolink were only detected within the Southeast Prairies BUL (one of the state-owned Burchard Lake sites and at both of the privately-owned Johnson County sites).
Grasshopper sparrows (Ammodramus savannarum), eastern meadowlarks (Sturnella magna) and bobolinks (Dolichonyx oryzivorus) had the greatest reproductive success rates (both annual and Mayfield), which were comparable to those reported by Ingold in 2002 for these species.
