Kenneth F. Higgins Harold A. Kantrud 1992 We summarized biological and ecologic characteristics of 2490 nests of 16 species of upland-nesting, non-passerine birds of northern grasslands found during 1963 through 1991. Nest initiation and hatch dates, clutch sizes, nest fates, causes of failure, success rates of nests among major habitat types and land uses, and vegetation measurements at nest sites are analyzed. application/pdf en North Dakota Natural Science Society Nest and nest site characteristics of some ground-nesting, non-passerine birds of northern grasslands article
