Range

Discussion

In spring, visiting a Yellow-headed Blackbird colony in a marsh or slough is an exciting experience. The surrounding water provides safety but often limits the nesting habitat; crowding is thus inevitable. Some males are always in display flight, with head stooped, feet and tail drooped, wings beating in a slow, accentuated way. Some quarrel with neighbors over boundaries while others fly out to feed. Approaching predators are mobbed by clouds of Yellow-headed Blackbirds and neighboring Red-wings, which nest in the drier stands of cattails.

Nesting

3-5 brown-speckled whitish eggs in a basket woven around several strong stalks. Nests in colonies.
