Larids, Scolopacids, And Passerines Exploiting Ephemeral Prey At Talan Island, Russia, Eric P. Hoberg, Alexander I. Kondratiev, Alexander S. Kitaysky

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

We report an unusual multispecies foraging assemblage that included larids, shorebirds and passerines which exploited a highly concentrated and ephemeral prey source over a period of three days in July and August 1988. During studies of breeding biology, food-habits and host-parasite ecology among a diverse colonial avifauna at Talan Island in the northern Sea of Okhotsk (59°18'N; 149°02'E) we observed the formation of mixed-species flocks during extreme high tides of July 31, August 1, and August 13, 1988.

Spring 1992 Occurrence Report

Nebraska Bird Review

During the reporting period from January 1 through June 30, 1992, 305 species were observed in Nebraska. The reports came from 56 counties, and ranged from one-date observations to the six-month range. For comparison, there were 301 species recorded in 1991 with reports from 34 counties. The number of counties was increased significantly in 1992, particularly in the western part of Nebraska.

Records covering the six-month period, or several dates over a shorter span of time, are presented in Table 1. The same species are listed on facing pages (except for page 136) for two groups of counties, which are …

Notes On Bird Sightings

Nebraska Bird Review

Brown Pelican in Nebraska. A BROWN PELICAN arrived at DeSoto Wildlife Refuge sometime during the last week of April 1992 and was still there on May 8 with a flock of WHITE PELICANS.

Longspurs, Black Scoters, and Cormorants. Just after the snowstorm on April 20-21, 1992, I saw LAPLAND LONGSPURS south of Bellevue, feeding on a windswept patch of ground. In their midst were two CHESTNUT-COLLARED LONGSPURS, which rarely migrate through eastern Nebraska. On April 28, 1992, I saw two BLACK SCOTERS swimming on the Missouri River by Child's Hollow in Fontenelle Forest. I also saw DOUBLE-CRESTED CORMORANTS swimming on …

1990 Nebraska Nesting Reports, Norma Johnson-Mueller, Rosalind Morris

Nebraska Bird Review

The number of counties covered and the number of observers decreased in 1990 when compared with the previous three years. In 1990, only least tern and piping plover nests were recorded in 9 of the 36 counties by 4 of the 23 observers. The information on these two species is presented in Table 1. Observers included Mark Brohman, John Dinan, and Greg Wingfield ( Nebraska Game and Parks commission), John Sidle (U.S. Fish and Wildlife Service), Eileen Kirsch, and Jeanine Lackey.

Nesting records of other species are given in Table 2 (pages 66-69).

Peregrine Falcon Nesting Success In Omaha, Nebraska, Rosalind Morris

Nebraska Bird Review

During May and June 1992, there were several articles in the Omaha World-Herald on a pair of Peregrine Falcons, which chose the top of the 28-story Woodmen Tower for a nest site. The male was one of a group of chicks brought from the University of Minnesota and raised on the top of Woodmen Tower. He was released from the Tower in 1989 and has returned each year since then. In 1992 he came with a mate, who had been released from a building in Des Moines, Iowa, in 1991.

Three eggs were laid in the hack box on consecutive …

Nebraska Ornithologists' Union Winter Meeting, Kearney, Nebraska, Scott Purdy

Nebraska Bird Review

About 30 people attended the meeting at the Ramada Inn on February 28-29 and March 1, 1992. On Friday evening, hors d'oeuvres were enjoyed while watching videos on the snowy owl, golden eagle, and identification of waterfowl.

The weather was unusually mild through the weekend, with temperatures in the 70-to-80-degree range. An early morning field trip to Rowe Sanctuary provided a fantastic show of Sandhill Cranes, geese, ducks, and Bald Eagles. Field trips were made to other birding spots on Saturday and Sunday mornings. A total of 63 species was seen in eight counties. The list of species is given …

Review Of 'My Way To Ornithology' By Olin Pettingill, Jr., Paul A, Johnsgard

Nebraska Bird Review

Most Nebraskans who recognize this author's name probably will remember him as a cinematographer and lecturer in the Audubon Screen Tour series. The series was a regular part of live entertainment in Lincoln and Omaha until the early 1960s.

Other bird-oriented people will know that Pettingill wrote two of the first and still best regional bird-finding books (detailed guidebooks to bird-finding localities in the states east and west of the Mississippi, respectively). Perhaps still others will remember him as a one-time teacher of ornithology at Carleton College and the University of Michigan Biological Station, or as a director of the …

Reaction Of Starlings To A Dark-Phase Red-Tailed Hawk, Barbara L. Wilson

Nebraska Bird Review

The role of polymorphism in bird plumage has been debated. One theory is that prey species become familiar with the common plumages of raptors and avoid them, but are unlikely to recognize unusual plumages as indicating dangerous birds (Clarke 1969). In other words, the rare plumage acts as a sort of disguise. This theory assumes that prey learn the appearance of their predators, but since prey that encounter hawks often end up dead, the opportunity for learning may be limited (Arnason 1978). An incident at Bellevue, Nebraska supports the hypothesis that an unusual color phase can act as a disguise.

Lek Formation In Sage Grouse: The Effect Of Female Choice On Male Territory Settlement, Robert M. Gibson

School of Biological Sciences: Faculty Publications

Previous studies of female choice in sage grouse, Centrocercus urophasianus, have identified two processes that could drive the local clustering of male territories at leks: (1) fidelity of females to previous mating sites (“temporal spillover” hypothesis), and (2) “spatial spillover” of matings from an attractive male to his immediate neighbors (“hotshot” hypothesis). The effects of each process on male territory settlement were investigated using observations of the resettlement of vacant territories and of individual site fidelity during a 7-year field study. The frequency with which vacant territories were resettled both within and between seasons increased with mating success of …

Crane Music, Paul A. Johnsgard

Paul Johnsgard Collection

Cranes are the stuff of magic, whose voices penetrate the atmosphere of the world's wilderness areas, from arctic tundra to the South African veld, and whose footprints have been left on the wetlands of the world for the past 60 million years or more. They have served as models for human tribal dances in places as remote as the Aegean, Australia, and Siberia. Whistles made from their wing bones have given courage to Crow and Cheyenne warriors of the North American Great Plains, who ritually blew on them as they rode into battle. These birds' wariness, gregariousness, and regularity of …

Habitat Use By Florida Sandhill Cranes On The Kissimmee Prairie In Central Florida, Mary Anne Bishop

Proceedings of the North American Crane Workshop

Radio-tagged Florida sandhill cranes (Grus canadensis pratensis) were monitored for habitat use during 1985 and 1986 on the Kissimmee Prairie in central Florida. For both breeding and nonbreeding cranes, 93 % of the daytime locations were in 3 habitat types: cropland and plowed pasture, improved pasture, and palustrine emergent wetlands. Improved pasture was the most frequently used daytime habitat for both social classes. Radio locations were divided among 4 time blocks (3 diurnal, 1 nocturnal) and 4 3-month seasons. Time-of-day effects for use of wetlands and improved pasture were only marginally significant (1' < 0.08 and l' < 0.09, respectively) for breeders and not significant (1' < 0.30 and l' < 0.43, respectively) for nonbreeders. There was no significant difference in habitat use by breeders among seasons. Chi-square analyses of diurnal locations indicated that 4 of the 6 breeding cranes monitored used palustrine emergent wetlands more than their availability. The selection for wetlands reflects not only the rich food sources available, but also their use as midday loafing and drinking sites and as a source of cover that the upland habitats do not offer.

The Ecology Of Native Grassland Macroinvertebrates And Feeding Ecology Of Sandhill Cranes, Craig A. Davis, Paul A. Vohs

Proceedings of the North American Crane Workshop

The ecology of native grassland macroinvertebrates along the Platte River in central Nebraska and their role in the feeding ecology of sandhill cranes (Grus canadensis) was examined on 3 native grasslands along the Platte River during late winter-early spring, 1989 and 1990. Four hundred forty-four soil samples from the study area were sorted for macroinvertebrates. Environmental factors such as soil moisture, water table depth, soil texture, and plant species composition were recorded from each soil collection site. Fifteen sandhill cranes, observed feeding for 40 minutes, were collected from 1 of the study areas. Maeroinvertebrates were collected from 4 …

Progress In Satellite Tracking Cranes, David H. Ellis, Dwight G. Smith, Glenn H. Olsen, Mark R. Fuller, Steven E. Landfried, Hiroyoshi Higuchi, Charles H. Vermillion

Proceedings of the North American Crane Workshop

We review the history of tracking cranes with satellite telemetry and identify some of the difficulties in designing satellite transmitters and harnesses for cranes. Miniaturization of these transmitters and a plethora of harnessing experiments since 1989 allow us to recommend limited application of this technology to all species of cranes. We are still uncertain, however, if cranes harnessed with satellite telemetry devices are able to reproduce after migration. Because of this uncertainty, we urge caution in the use of this technology, especially with breeding adults in severely endangered popUlations. This manuscript also describes continuing research needs.

Contaminant Residues In Sandhill Cranes Killed Upon Striking Powerlines In Central Nebraska, Timothy E. Fannin

Proceedings of the North American Crane Workshop

In 1989 and 1990, 58 sandhill cranes (Grus canadensis) were collected along the central Platte River in Nebraska during a study of mortality caused by powerline impact. Brains were assayed for acetylcholinesterase activity; gut contents were analyzed for residues of 25 organophosphate and 6 carbamate compounds; and livers were analyzed for 20 inorganics (including lead, mercury, and boron) and 22 organochlorine chemicals. Brain acetylcholinesterase activities appeared to be within normal ranges, and no measurable organophosphate or carbamate residues were found in the gut contents of 5 birds with the lowest brain enzyme activities. Heptachlor epoxide, oxychlordane. p,p' -DDE, …

Distribution Of Sandhill Cranes In The North Platte River Valley: 1980 And 1989, Martin J. Folk, Thomas C. Tacha

Proceedings of the North American Crane Workshop

We observed the abundance, diurnal distribution, and habitat use of sandhill cranes (Grus canadensis) in the North Platte River Valley (NPRV) in 1989 for comparisons to similar data from 1979 to 1980. Sandhill cranes traveled farther from nocturnal roosts to diurnal feeding sites and use of the NPRV was lower in 1989 as compared to 1979~80. Presence of cranes in corn stubble and pasture increased from 1980 to 1989, while presence in alfalfa and palustrine wetlands decreased. Plowing of corn stubble fields and drought conditions in 1989 may have influenced crane distribution, abundance, and habitat use.

Identification Of Segregating Haplotypes Of The Major Histocompatibility Complex In Cranes, Susan I. Jarvi, George F. Gee, W. Elwood Briles, Marcia M. Miller

Proceedings of the North American Crane Workshop

The major histocompatibility complex (Mhc) is thought to exist in all vertebrate species. In most species, a high degree of polymorphism is maintained in this region at mUltiple loci which encode molecules that serve in the presentation of foreign antigens to T lymphocytes (Klein 1986, Miller 1991). In this investigation, serological and recombinant DNA techniques are being used to investigate genetic diversity at the Mhc in several species of cranes, to investigate questions of paternity in some instances, and to develop practical methods for determining Mhc haplotype •. Blood samples are provided by the Patuxent Wildlife Research Center (PWRC), Laurel, …

The Plight Of Cranes: A Case Study For Conserving Biodiversity, J. Christopher Haney, Mark E. Eiswerth

Proceedings of the North American Crane Workshop

Cranes provide an exemplary case for evaluating conservation policy because (1) they are a charismatic group with high public visibility, (2) as migratory vertebrates they provide an umbrella for the protection of aquatic habitats and a wider set of species, (3) they are a widely-distributed avian family, consequently protection efforts have favored international cooperation, (4) genetic and taxonomic relationships have been studied, and (5) populations of at least 7 crane species are threatened, endangered, or otherwise considered at direct risk. We use comparisons among the world's cranes to show how biogeographic, taxonomic, and genetic data bases can be linked for …

History And Economic Impact Of Crane-Watching In Central Nebraska, Gary R. Lingle

Proceedings of the North American Crane Workshop

The first documentation of the Platte and North Platte rivers' importance to sandhill cranes (Grus canadensis) dates from the late 1800's. Except for a few ornithologists, it was not until the mid-1970's that crane-watching became popular. During the last 10 years, this interest has become a multi-million dollar tourist industry that attracts people from around the globe who seek to witness this vernal spectacle of half a million cranes. More than half of the former riverine habitat has been abandoned by the cranes, largely because of irrigation and hydropower projects that drain the river and enable forests to …
