Notes On The Nesting Biology Of Pygmy Nuthatches In Nebraska, Wayne Mollhoff Dec 1997

Notes On The Nesting Biology Of Pygmy Nuthatches In Nebraska, Wayne Mollhoff

Nebraska Bird Review

Introduction

Pygmy Nuthatches (Sitta pygmaea) were considered to be no more than casual or rare winter visitors to the northwest part of Nebraska by previous investigators (Bruner et al. 1904; Swenk 1918; Haecker et al. 1945; Rapp et al. 1958, 1971). I. S. Trostler's earlier comment that the species was "a rare resident, breeds in Omaha" (Bruner 1896) was later felt to be in error, as evidenced by Bruner's later comment that it was, "A fall and winter visitor . . . not breeding in the state" (Bruner et al. 1904).

The first evidence of breeding was the …


Whooping Crane Sightings, August 1997-January 1998, Steven Anschutz Dec 1997

Whooping Crane Sightings, August 1997-January 1998, Steven Anschutz

Nebraska Bird Review

Cooperation throughout the Whooping Crane flyway continues to be excellent, and special thanks go out to each participant. Between 1977 and 1988, 132 juvenile birds were color-marked on the breeding grounds, and 40 were accounted for during the winter of 1997-98. Fourteen color-marked Whooping Cranes were observed during the fall migration. All sightings of color-marked birds are maintained at the Grand Island office. The importance of observers looking closely for the colored leg bands cannot be overemphasized.

Based on observations of the breeding grounds during the summer of 1997, about 192 Whooping Cranes were expected to arrive at the Aransas …

Puncturing Ability Of Bat Canine Teeth: The Tip, Patricia W. Freeman, William N. Weins Dec 1997

Puncturing Ability Of Bat Canine Teeth: The Tip, Patricia W. Freeman, William N. Weins

University of Nebraska State Museum: Mammalogy Papers

Casts of upper canine teeth of 15 species of microchiropteran bats were fixed securely into a testing machine and made to puncture the bloom side of an apple. The force necessary to break through the surface of the apple was regressed against both shape of the tip of the canine and the size of the animal. Sharper tips require less force to puncture than blunt ones. Results were also verified using giant two-dimensional models of Plexiglas™ with sharp and blunt tips that were loaded onto a Plexiglas™ beam. Fringes, or stress lines, are more highly concentrated at the point of …


Survey Of Mollusks Of The Niobrara River: Final Report, Patricia W. Freeman, Keith Perkins Sep 1997

Survey Of Mollusks Of The Niobrara River: Final Report, Patricia W. Freeman, Keith Perkins

School of Natural Resources: Faculty Publications

We surveyed the mollusks of the Niobrara River in Nebraska from 1992–1996. We found two species of unionid clams and ten species of snails that either must live in water or near water. Both clams and snails are poorly sampled in the state, however we attribute the low number of species of unionid clams in the Niobrara to its cold, fast flow and rocky bottom. In contrast, the Platte River is slower moving with a muddy bottom and has at least 11 species of unionid clams. Each species has been mapped with latitude/longitude coordinates. Specimens have been curated and are …

Remembering Doris Gates, A Great Teacher, Mark M. Peyton Sep 1997

Remembering Doris Gates, A Great Teacher, Mark M. Peyton

Nebraska Bird Review

Doris Gates (1915-1983) taught Biology at Huntley, NE from 1938-1941, North Platte from 1941-1955, and Chadron State College from 1955-1974. She lived until her death at the foot of "Rush No More Butte" south of Chadron, was a member of the North Platte Tout Bird Club, and served as President of the Nebraska Ornithologists' Union and Editor of The Nebraska Bird Review.

Doris included plants and birds in her lectures on Biology, but she taught much more than that because she understood the beauty of life. She believed that beauty was in what you did rather than what you looked …

Whooping Crane Sightings During March-May 1997 Migration, Steven Anschutz Sep 1997

Whooping Crane Sightings During March-May 1997 Migration, Steven Anschutz

Nebraska Bird Review

During the 1996-97 winter, 158 (143 adult/subadult and 15 juvenile) Whooping Cranes stayed at the Aransas National Wildlife Refuge in Texas. Two early migrants in Nebraska were an adult-plumaged bird first observed on 9 March, and a juvenile confirmed on 19 March. Neither of these birds wintered at Aransas, so the total population was therefore 160 (144 adult/subadult and 16 juvenile). All 158 cranes wintering at Aransas were present 3 April, but by 10 April, about 103 cranes had begun to migrate, and by 24 April, only 13 cranes were still at Aransas. All cranes had migrated by 6 May.


Mountain Plover Nest In Kimball County, Stephen J. Dinsmore Sep 1997

Mountain Plover Nest In Kimball County, Stephen J. Dinsmore

Nebraska Bird Review

On 18 May 1995 I observed two adult Mountain Plovers 5 mi west and 1.25 mi north of Bushnell in southwest Kimball county. The birds were in an area of short-grass prairie interspersed with clumps of prickly pear and bare ground. I observed both birds almost continuously from 1-2 p.m. MDT. The first bird was along the road south of the fenceline, just after the road climbs on top of the plateau. The second bird was about 0.1 mi to the north on the west side of the road. Both birds were medium-sized, plain shorebirds, similar in shape and posture …

Shorebird Migration In The Eastern Rainwater Basin—Spring 1997, Joel G. Jorgensen

Nebraska Bird Review

The Rainwater Basin is arguably Nebraska's most productive area for observing migrant shorebirds, especially in spring. After several years of irregular shorebirding in the region, in 1997 I decided to perform regular shorebird censuses in the eastern portion of the RWB (eRWB).

The Ornithologists' Unions of Iowa, Nebraska, and South Dakota held a Tristate spring meeting at Sioux City, IA on 16-18 May, organized by Bill Huser and committee members from Iowa and South Dakota, and hosted by the Loess Hills Audubon Society from South Sioux City, NE. Field trips were made into nearby areas of all three states. During an indoor session, a paper on "Migrating Hawks along Iowa's Loess Hills" was presented by Loren and Babs Padelford. The banquet speaker was Ken Kaufman, who spoke on "Bird study and natural history in the 21st century." During the weekend, a total …


Summer Field Report, June-July 1997, W. Ross Silcock, Joel G. Jorgensen Sep 1997

Summer Field Report, June-July 1997, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

A couple of preliminary notes: in the accounts below we have noted for several species "Reports were routine." This means that these species, mostly common in occurrence, were indeed present and reported, but the reports did not include unusual arrival or departure dates or high counts. For this Summer Report, observers are encouraged to report high counts on their BBS routes, as well as nesting data such as egg and fledging dates. Finally, this report includes a few observations from 1996.

In general, this was a rather routine summer period. The only real rarity was, however, a good one, a …


International Shorebird Survey Report For Southeastern Nebraska—Spring 1997, Kevin Poague, John Dinan Sep 1997

International Shorebird Survey Report For Southeastern Nebraska—Spring 1997, Kevin Poague, John Dinan

Nebraska Bird Review

In 1974, Manomet Observatory in Massachusetts organized the International Shorebird Survey (ISS) to collect information on shorebirds during migration. The project is intended to monitor shorebird population trends and to identify major migration routes, timing, and locations of staging areas. More than 600 contributors from 38 states of the United States, and countries, territories, and commonwealths throughout the hemisphere have contributed data since the program's inception. The Nebraska Game and Parks Commission collected data for the ISS in the eastern Rainwater Basin area (Clay, Fillmore, York, and Seward counties) from 1993-1996.

Nebraska's eastern saline wetlands, located in or near the …


Two Hybrid Diving Ducks At Cunningham Lake, Douglas County, Joel G. Jorgensen Sep 1997

Two Hybrid Diving Ducks At Cunningham Lake, Douglas County, Joel G. Jorgensen

Nebraska Bird Review

During the spring of 1997 I had the opportunity to observe and study two apparent hybrid diving ducks at Glenn Cunningham Lake, Douglas County. Both birds appeared to be mature males in breeding plumage. One bird was a suspected Redhead x Canvasback hybrid and the other was a suspected Common Goldeneye x Hooded Merganser hybrid. Sibley (1994) states that both hybrid combinations occur "occasionally."

1996 (Eighth) Report Of The Nou Records Committee, Mark A. Brogie

Nebraska Bird Review

The functions and methods of the NOU Records Committee are described in its bylaws (NOU Records Committee 1986). The committee's purpose is to provide a procedure for documenting unusual bird sightings and to establish a list of all documented birds for Nebraska. THE OFFICIAL LIST OF THE BIRDS OF NEBRASKA was first published in 1988 (NOU Records Committee 1988) and has been appended six times (Mollhoff 1989, Grenon 1990, 1991, Gubanyi l996a, 1996b, 1996c). An update of THE OFFICIAL LIST OF THE BIRDS OF NEBRASKA was last published in 1997 (NOU Records Committee 1997) and includes the additions and changes …

Diet Of A Relict Population Of The Eastern Woodrat In Nebraska, Hugh H. Genoways, Patricia W. Freeman, Mary K. Clausen Sep 1997

Diet Of A Relict Population Of The Eastern Woodrat In Nebraska, Hugh H. Genoways, Patricia W. Freeman, Mary K. Clausen

University of Nebraska State Museum: Mammalogy Papers

The relict population of Neotoma floridana occurring along the Niobrara River in north-central Nebraska was found to have a diet composed of 38 types of food items of which 37 types were plants. Unique features of the summer diet of this population were a higher than expected use of red cedar (Juniperus virginiana) and invertebrates as food items.

Nebraska's Flying Mammals, Patricia W. Freeman, Kenneth N. Geluso, J. Scott Altenbach Jul 1997

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

University of Nebraska State Museum: Mammalogy Papers

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 …


Systematics Of The Freshwater Amphipod Genus Crangonyx (Crangonyctidae) In North America, Jun Zhang Jul 1997

Systematics Of The Freshwater Amphipod Genus Crangonyx (Crangonyctidae) In North America, Jun Zhang

Biological Sciences Theses & Dissertations

The systematics of the amphipod genus Crangonyx of North America (north of Mexico) is revised, based on available collections (ca. 2240) and literature dealing with the genus. A grand total of 42 North America species of Crangonyx are recognized in the present study, 24 of them new to science. All species are described or redescribed and figured, utilizing external morphological features. Keys to both species groups and individual species are given. Phylogenetic trees are built using computer programs (PAUP, Hennig86, MacClade) based on 26 characters. Wagner parsimony produced 18 parsimonious trees and Fitch parsimony produced 45 trees. The consensus tree …


Ecological Relationships Between The Marsh Rice Rat (Oryzomys Palustris) And The Meadow Vole (Microtus Pennsylvanicus) In Two Virginia Tidal Marshes, Christopher P. Bloch Jul 1997

Ecological Relationships Between The Marsh Rice Rat (Oryzomys Palustris) And The Meadow Vole (Microtus Pennsylvanicus) In Two Virginia Tidal Marshes, Christopher P. Bloch

Biological Sciences Theses & Dissertations

Small mammals were trapped for 23 months on two live trap grids in tidal marshes in Northampton County, on the Eastern Shore of Virginia, to examine ecological relationships between the marsh rice rat (Oryzomys palustris) and the meadow vole (Microtus pennsylvanicus). Population density, survival rates, capture probability, recruitment, residence time, and home range size were calculated for each species. Patterns of reproductive activity and fluctuations in mean weight were also observed.

There were considerable differences in population dynamics between the two sites. At Grid 2, where vegetative cover was more abundant, population densities of rice rats and meadow voles …


The Annual Reproductive Cycle Of Oryzomys Palustris In A Virginia Tidal Marsh, Erin A. Dreelin Jul 1997

The Annual Reproductive Cycle Of Oryzomys Palustris In A Virginia Tidal Marsh, Erin A. Dreelin

Biological Sciences Theses & Dissertations

The objectives of my study were to determine when the marsh rice rat (Oryzomys palustris) begins and ends reproduction during the year, if there are seasonal changes in litter size, and the weight at which sexual maturity is reached. Monthly samples of rice rats were trapped from May 1995 to May 1996 in Northampton County, Virginia. Rice rats were trapped with Fitch live traps, euthanized in the field, and brought to the lab for necropsy. Data from two other studies of rice rats in Northampton County were also examined. Potential breeders did not reproduce with equal intensity throughout the …


Bat Research, Patricia W. Freeman Jul 1997

Bat Research, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

In our research, we capture bats with a net 50 to 200 feet long set up between poles. Usually we net over water to capture bats as they drink or forage. Sometimes we rig the net so it can be moved up and down like a sail between two secured lines or poles so we can sample what flies high among the trees. Netting helps us to discover where each species occurs in the state [of Nebraska], and we also can determine an individual's age, sex, reproductive condition, and diet.
