Shaffer 2023 <p>Keys to Bobolink (<i>Dolichonyx oryzivorus</i>) management are providing large areas of suitable habitat (for example, native or tame grasslands of moderate vegetative height and density, low shrub density, and moderate litter and forb cover), and protecting nesting habitat from disturbance during the breeding season. Bobolinks have been reported to use habitats with 10–166 centimeters (cm) average vegetation height, 6–75 cm visual obstruction reading, 17–65 percent grass cover, 3–50 percent forb cover, less than or equal to (≤) 22 percent shrub cover, ≤38 percent bare ground, 5–39 percent litter cover, and ≤9 cm litter depth.</p> application/pdf 10.3133/pp1842LL en U.S. Geological Survey The effects of management practices on grassland birds—Bobolink (<em>Dolichonyx oryzivorus</em>) reports
