Discussion Although primarily a marsh bird, the Red-winged Blackbird will nest near virtually any body of water and occasionally breeds in upland pastures. Each pair raises two or three broods a season, building a new nest for each clutch. After the breeding season, the birds gather with other blackbirds in flocks, sometimes numbering in the hundreds of thousands. Although blackbirds are often considered pests because they consume grain in cultivated fields, farmers benefit because the birds consume harmful insects during the nesting season.
