Distribution of the Yellow-headed Blackbird. This species winters locally south of the dotted line in the east and west, and south to the dotted line in Mexico.
The Yellow-headed Blackbird, although most numerous in prairie wetlands, is a conspicuous breeding bird in deep-water, emergent wetlands throughout nonforested regions of western North America. Its generic and specific name, Xanthocephalus, means "yellow head," a tribute to the male's striking plumage. Highly social, these large-bodied blackbirds are polygynous, nesting on grouped territories. Postbreeding birds eat mostly grains, often forming large flocks that forage in uplands and roost in wetlands. Flocks migrate to the southern United States and Mexico for the winter.
The first detailed description of this species was by Prince Charles Lucien Bonaparte (
Bonaparte, C. L. (1825b). American ornithology, or the natural history of birds inhabiting the United States, not given by Wilson. Vol. 1. Philadelphia: Carey, Lea & Carey.
Bonaparte 1825b), although Thomas Say (
