Sharp‐Tailed Grouse In The Nebraska Sandhills Select Residual Cover Patches For Nest Sites, William L. Vodehnal, Gregory L. Schenbeck, Daniel W, Uresk

Nebraska Game and Parks Commission: Staff Research Publications

We evaluated selection and availability of residual cover (dead standing herbage) by sharptailed grouse (Tympanuchus phasianellus) at time of nest‐site selection in an intact and annually grazed grassland. We used radiotelemetry in 1988–1990 to locate 147 nests in the sandhills of Nebraska, USA, and classified 121 as initial nests and 26 as renests. We used visual obstruction readings (VOR) to measure the height and density of residual cover at nests and 373 landscape‐scale transects around leks (trap sites). We excluded 77 nests from vegetation analysis because green herbage or early livestock grazing compromised residual cover measurements. Most females …
