Mate Choice In Lekking Sage Grouse Revisited: The Roles Of Vocal Display, Female Site Fidelity, And Copying, Robert M. Gibson, Jack W. Bradbury, Sandra L. Vehrencamp
Mate Choice In Lekking Sage Grouse Revisited: The Roles Of Vocal Display, Female Site Fidelity, And Copying, Robert M. Gibson, Jack W. Bradbury, Sandra L. Vehrencamp
School of Biological Sciences: Faculty Publications
In lekking sage grouse (Centrocercus urophasianus), females exhibit relatively unanimous mate choice for particular males, but a satisfactory explanation for this unanimity has been elusive. We present analyses of mating distributions from two leks over 4 years that provide evidence for female choice based on differences in vocal display performance of males, the locations at which hens mated in the previous year, and the choices of other females (copying). The unanimity of female choice varied markedly among leks and years in correlation with changes in the mean numbers of hens that mated at the same time and hence …
Black-Bellied Plover In Buffalo County
Black-Bellied Plover In Buffalo County

Nebraska Fauna: American White Pelican, Paul A. Johnsgard
Nebraska Fauna: American White Pelican, Paul A. Johnsgard
Papers in Ornithology
Few birds are more familiar to the average person than are white pelicans, but few Nebraskans also realize that thousands of these birds migrate through the state every year, and hundreds stop over to spend the summer on some of our larger lakes and reservoirs. No pelicans breed in Nebraska, but the nearest breeding area is only a short distance north of us, at LaCreek National Wildlife Refuge, near Martell, South Dakota. Since it requires three--or more probably four--years for white pelicans to become sexually mature, many of the immature birds simply stop off in Nebraska rather than completing their …

Total Body Water And Body Composition In Phalaropes And Other Birds, Hugh I. Ellis, Joseph R. Jehl Jr
Total Body Water And Body Composition In Phalaropes And Other Birds, Hugh I. Ellis, Joseph R. Jehl Jr
Biology: Faculty Scholarship
Contrary to some reviews, total body water (TBW) may fall below the expected value of about 65% in birds if measured as a percentage of total body mass. However, water constitutes a relatively stable proportion (659%-70%) of body composition when measured as a percentage of lean body mass (LBM). We demonstrate this by using data from two migratory phalaropes (Phalaropus tricolor and Phalaropus lobatus), which exhibit inverse relationships between TBW and body mass and between TBW and fat content. As the phalaropes fatten before migration, lipids increase but not at the expense of water, which also increases with gains in …

Eagles
Nebraska Bird Review
For the past three years, the Central Nebraska Public Power District has operated an Eagle Viewing Center at our J-2 Hydropower plant south of Lexington, and this past year below Kingsley Dam on Lake Ogallala.
The following are some results recorded at the sites:
At J-2 Hydroplant:
January 1990-0bservations were recorded on 23 days. 263 birds were sighted for a daily average of 11.4 per day. The highest count was 20 birds on January 2.
February 1990-0bservations were recorded on 15 days. 28 birds were sighted for a daily average of 1.9 per day. The highest count was 16 birds …
A Nesting Report Of A Wilson's Phalarope In Lancaster County, Larry Einemann
A Nesting Report Of A Wilson's Phalarope In Lancaster County, Larry Einemann
Nebraska Bird Review
Only once before has a nesting record of Wilson's Phalarope (Phalaropus tricolor) been reported in Lancaster County. This report is in The Nebraska Bird Review, December 1985. Employees of the Nebraska Game and Parks Commission discovered two fledglings at a site in the northeast part of the county at 98th and Ashland Road. The two fledglings were found in a wet meadow. They were accompanied by two male and one female phalaropes. The sighting was made on 13 June 1985.
On 7 June 1991 I visited Arbor Lake, a recently purchased salt marsh about one mile north …

Some Birds Of The Pony Lake Area Of The Eastern Sandhills, Nebraska, James E. Ducey, Jerry Schoenenberger
Nebraska Bird Review
A partial survey was made of the bird life in the vicinity of Pony Lake, located about 15 miles south of Newport, in portions of sections 17-20, T28N, RI7W, Rock County.
Pony Lake was reportedly named according to a legend from "early days" when a native American was thrown and killed on its banks by a wild pony (Perkey, 1982). Originally Pony Lake was reported to be 20 feet deep (lake history based on conversations and observations of Jerry Schoenenberger). In the late 1800s, possibly 1900-1910, a town site was platted on the southwest corner of the lake. Construction included …
Spring 1991 Whooping Crane Report
Spring 1991 Whooping Crane Report
Nebraska Bird Review
The following is a synopsis of the report from the U.s. Fish and Wildlife Service with regard to Whooping Crane sightings from Spring 1991. The report consists of confirmed, probable, and unconfirmed sightings during the season. These terms are defined in NBR 56:79.
The USFWS states that 135 Whooping Cranes began the spring migration, compared to 142 in 1990. This drop of seven birds represents the first population decrease since 1981. Most confirmed sightings en route to Wood Buffalo National Park, Canada, were made between April 14 and April 23. Overcast skies and low visibility delayed the usual early April …

Sighting Information And Analysis
Nebraska Bird Review
Rather than do a county-by-county analysis as has been done in the past, since this count starts a new year, I thought I would comment on the sightings presented using both information provided by the observers and appropriate reference materials. This current report only documents those species which are listed by the Records Committee as needing documentation, or those which merit comment due to significant out-of-range or out-of-season status. A more thorough study, including nesting information provided by the reporters, will appear in the next NBR.
Pileated Woodpecker Responds To Owl Tape [Notes], Rick Wright
Pileated Woodpecker Responds To Owl Tape [Notes], Rick Wright
Nebraska Bird Review
Suspecting the Pileated Woodpecker (Drycopos pileatus) first reported in fall 1990 might still be present, I spent much of a late March visit to Nebraska in Fontenelle Forest, Sarpy County, looking and listening for the bird without success. Late on the morning of March 26, 1991, Tanya Bray, Babs Padelford, and I wele at the mouth of Handsome Hollow in Fontenelle Forest, the site of the most recent observations. Seeing and hearing nothing we played the recorded song of Eastern Screech-Owl (Otus asio), hoping to attract passerines. Within seconds, a female Pileated Woodpecker flew silently from …
Spring 1991 Occurrence Report
Nebraska Bird Review
For the first six months of 1991, 301 species were reported from 34 counties.

Factors Influencing Distribution And Abundance Of The Loggerhead Shrike (Lanius Ludovicianus Migrans) In South-Central Illinois, Eric Lantz Smith
Factors Influencing Distribution And Abundance Of The Loggerhead Shrike (Lanius Ludovicianus Migrans) In South-Central Illinois, Eric Lantz Smith
Masters Theses
The loggerhead shrike (Lanius ludovicianus) is listed as a threatened species in Illinois as a result of population declines that have occurred since approximately 1900. Although Graber et al. (1973) reported that this species had been largely extirpated from the northern two-thirds of Illinois by 1965, there has been no research on shrike distribution or abundance in the state since that time. Consequently, a roadside survey was completed in 32 south-central Illinois counties to delineate the abundance of loggerhead shrikes in the study area and attempt to relate their abundance to land-use patterns among counties surveyed.

Mountain Plover Sighted In Kimball County, Mary Clausen
Mountain Plover Sighted In Kimball County, Mary Clausen
Nebraska Bird Review
In late April of 1990 I went to Kimball Co. to search for Mountain Plovers. Over a period of a week I walked several sections where Mountain Plovers have been sighted in the past. No Plovers were found at that time.
After I returned to my office in Lincoln, Fritz Knopf (Avian Studies Biologist, U.S. Fish and Wildlife Service, Colorado) contacted me to discuss Mountain Plover nesting habitat and behavior. Fritz offered to make a quick drive around Kimball Co. to see how the habitat in Nebraska compared to that used by nesting Mountain Plovers in Colorado.
