Least Shrew (Cryptotis Parva ) In Extreme West-Central Nebraska, Keith Geluso, Jeremy A. White, Michael A. Bogen

Biology Faculty Publications

During the past 35 years, the least shrew (Cryptotis parva) has expanded its distribution along riverine and other mesic corridors in western parts of its distribution, although some recently discovered populations in the West might represent relicts of a previous Pleistocene distribution. In Nebraska, the least shrew originally was known only from eastern and central parts of the state, but recent records are now available from extreme west-central Nebraska and the northwestern corner of the state. Our record from west-central Nebraska probably represents recent westward expansion of C. parua along the North Platte River. This capture in Scotts …

Reproduction And Seasonal Activity Of Silver-Haired Bats In Western Nebraska, Keith Geluso, Jeffrey J. Huebschman, Jeremy A. White, Michael A. Bogen

Biology Faculty Publications

Silver-haired bats (Lasionycteris noctivagans) were thought only to migrate through Nebraska; however, recent surveys in eastern Nebraska report summer records of females and their young. Our study in western Nebraska also shows that silver-haired bats are summer residents. We discovered the 1st reproductively active L. noctivagans in this part of the state. We caught lactating females and volant young in riparian forests along the North Platte River and in forested areas of the Pine Ridge. Previously, adult males were not known from Nebraska in summer, and only 4 records of L. noctivagans were known from western Nebraska during …

Nebraska's Flying Mammals, Patricia W. Freeman, Kenneth N. Geluso, J. Scott Altenbach

Biology Faculty Publications

They flit around at dusk in crazy patterns. They fly around street lights and dive at rocks thrown in the air. They have high-pitched squeaks and turn up in unexpected places. They have strange, little faces and bizarre ears. They have soft fur and a thin rubbery membrane across their long fingers. They are bats, Nebraska's only flying mammals.

Bats are mysterious. Is it because they come out at night and we come out in the daytime? Maybe it is because we associate flying with birds, not mammals. Bats are dark and foreboding, not brightly colored. At first, these mysterious …

The Origins Of Spring Migratory Staging By Sandhill Cranes And White-Fronted Geese, Roger S. Sharpe

Biology Faculty Publications

A most unusual avian migratory event takes place each .,pring in the Platte River basin of Nebraska between 98 and 102 degrees longitude (Fig. 1). In suitable habitats throughout this area large concentrations of Sandhill Cranes, Crus canadensis, and White-fronted Geese, Anser albifrons, develop and achieve peak populations in mid to late March. This phenomenon is traditional to the migratory habits of specific populations and occurs during the spring movement from wintering grounds in Texas, New Mexico, and Mexico to breeding grounds far to the north in Canada and Alaska. In both species groups of individuals drift in from wintering …
