Nebraska Bird Review
Two hundred ninety-one species, and the probability that the Snowy Owl on the DeSoto NWR Christmas Count would qualify as a Nebraska bird and the possibility that some of the Empidonax sp. reported were not otherwise reported, were reported from 13 "full-time" locations plus 9 "spot-check" locations, which included 27 counties. The figures for 1988 were 282 species from 14 "full-time" locations plus 14 "spot-check" locations, which included 49 counties. The figures for 1987 were 296, plus 2 possibilities, from 14 "full-time" and 4 "spot-check" locations; 1986, 293 and 1 possibility from 13 "full-time" and 4 "spot-check" locations.

Hematozoa Of Common Grackles (Quiscalus Quiscula Versicolor, Vieillot) In Central Arkansas, Arthur A. Johnson
Hematozoa Of Common Grackles (Quiscalus Quiscula Versicolor, Vieillot) In Central Arkansas, Arthur A. Johnson
Journal of the Arkansas Academy of Science
During the years 1977-84, 118 bronzed grackles, Quiscalus quiscula versicolor, Vieillot, of 132 examined were found infected with hematozoa. The eight species of symbionts collected from the infected birds included two microfilarial species (Chandlerella quiscali and Eufilaria hibleri), five apicomplexans (Haemoproteus quiscali, Leucocytozoon fringillinarum, Plasmodium matutinum, P. vaughani, P. sp.) and a flagellate (Trypanosoma ontarioensis). P. matutinum and T. ontarioensis represent new host records and all the protozoans represent new locality records. Comparisons are made of symbiont prevalance and diversity as this relates to seasons of the year, sex and age of the host. Comparisons are also made with previous …

Relationships Between Blood Parasites, Mating Success And Phenotypic Cues In Male Sage Grouse Centrocercus Urophasianus, Robert M. Gibson
Relationships Between Blood Parasites, Mating Success And Phenotypic Cues In Male Sage Grouse Centrocercus Urophasianus, Robert M. Gibson
School of Biological Sciences: Faculty Publications
In lek breeding Sage Grouse Centrocercus urophasianus in eastern California, male mating success is strongly correlated with individual differences in lek attendance, and in the rate and acoustic quality of courtship display, suggesting that these provide cues by which females choose mates. Increased lek attendance and high display rates also associated with elevated metabolic expenditure. This paper examines the hypothesis that the ability to commit energy to display is related to the incidence of blood parasites. A single hematozoan genus, Haemoproteus, was found in 37.5% of 184 Sage Grouse sampled over a five year period. Parasitism varied across years and …

Hawks, Eagles, And Falcons Of North America: Biology And Natural History, Paul A. Johnsgard
Paul Johnsgard Collection
I have tried to present an adequate if far from exhaustive survey of the general biology, ecology, and behavior of all the included species, written so as to be understandable to the interested layman as well as useful to the biologist who might be looking for relevant literature citations or trying to deal with a specific question without resorting to extensive library searches. The larger number of species of North American hawklike birds (31, compared to 19 owl species) has required that I keep the individual species accounts substantially shorter. I have excluded the New World vultures from consideration, primarily …

1986: A Nebraska Big Year, Mark A. Brogie
Nebraska Bird Review
In January of 1986 my brother, Ed M. Brogie, and I were tallying our lists for Nebraska when the question arose: "How many species of birds do you think one could see in Nebraska in one year?" The previous year (1985) had been the first year we had made a serious attempt at seeing western Nebraska species and chasing rarities in the state. Our efforts had yielded such birds as Bean Goose, Green-tailed Towhee, Black-necked Stilt, Red Phalarope, Lewis' Woodpecker, Sprague's Pipit, Cassin's Finch, Cassin's Kingbird, and King Eider. When 1985 ended, my Nebraska life list stood at 290 and …
Cassin’S Sparrow In Dundy And Chase Counties, Nebraska, W. Ross Silcock, Mark A. Brogie
Cassin’S Sparrow In Dundy And Chase Counties, Nebraska, W. Ross Silcock, Mark A. Brogie
Nebraska Bird Review
On 3 and 4 June 1989 Tanya Bray, Doug Rose, and I [W. Ross Silcock] traveled to Dundy Co. to look for two species: Chihuahuan Raven and Cassin's Sparrow. While we found no Ravens, we did find several Cassin's Sparrows.
All of the Cassin's Sparrows were found in sandy sage prairie habitat. At least six were found, in four different locations. The birds were located most easily by their skylarking behavior, although the song, once heard, is also useful for locating birds. Indeed, Doug Rose found the first Cassin's Sparrow by song. Once located, we were able to study individuals …
Notes [September 1989]
Nebraska Bird Review
“Scissor-tailed Flycatcher Nest in Cass County”: On 2 July 1989 Greg Hertel, Murray, Cass Co., reported an adult Scissor-tailed Flycatcher in his yard. He thought it had left the area, but Betty Allen and Ruth Green went down on 8 July to look for it, and they finally found it (a male) in Young Memorial Park. The next morning Betty took others down to see it and found a female on a nest on a 40-foot light pole used to floodlight the ball field.

Field Playback Of Male Display Attracts Females In Lek Breeding Sage Grouse, Robert M. Gibson
Field Playback Of Male Display Attracts Females In Lek Breeding Sage Grouse, Robert M. Gibson
School of Biological Sciences: Faculty Publications
Recent correlational studies of lekking sage grouse suggest that male vocal display attracts females. To test this hypothesis further, the natural displays of a territorial male were supplemented with the tape-recorded display of another reproductively successful individual. Significantly, more females approached the speaker's location on days when the recording was played, and also on nonplayback days immediately following a playback, than on other nonplayback days. Analysis of male displays indicated that females were responding to the playback itself rather than to changes in male behavior. The "after-response" following a playback suggests that some females present during a playback remembered its …

The Use Of Banding Recovery Data To Estimate Dispersal Rates And Gene Flow In Avian Species: Case Studies In The Red-Winged Blackbird And Common Grackle, William S. Moore, Richard A. Dolbeer
The Use Of Banding Recovery Data To Estimate Dispersal Rates And Gene Flow In Avian Species: Case Studies In The Red-Winged Blackbird And Common Grackle, William S. Moore, Richard A. Dolbeer
Biological Sciences Faculty Research Publications
Dispersal resulting in gene flow strongly affects the evolution of genetic structure in populations. This report describes statistical estimators of dispersal parameters based on USFWS banding recovery records. Finite-area studies of avian species yield estimates of root-mean-square (RMS) dispersal along a transect of about 1 km per generation. In contrast, estimates of RMS dispersal for the Red-winged Blackbird (Agelaius phoeniceus) and Common Grackle (Quiscalus quiscula), based on USFWS banding recovery records, are 94.6 and 111.4 km per generation, respectively. Distributions for both species are extremely leptokurtic, and confidence intervals based on jackknife statistics are large because the estimators are sensitive …
Habitat Use And Diet Analysis Of Breeding Common Barn Owls In Western Nebraska, Joseph A. Gubanyi M.S.
Habitat Use And Diet Analysis Of Breeding Common Barn Owls In Western Nebraska, Joseph A. Gubanyi M.S.
School of Natural Resources: Dissertations, Theses, and Student Research
I studied barn owl (Tyto alba) breeding biology in western Nebraska 1984-1986. I had greatest success capturing males (56% success) at night using trap doors at nest sites and females (91 % success) using hoop nets at nest sites during the day. Barn owls removed 16 of 23 tail-mounted radios. Eight birds were radio-tracked for 7-14.5 hours. The mean foraging range was 198 ha (32- 299 ha, n = 8) with < 1 % overlap among birds from adjacent nest sites. Field-tested telemetry error was high (mean displacements of radio-locations for 2 birds were 208 and 241 m). I found no relationship between percent cover in foraging habitat and reproductive success. I identified 10,140 prey items from 15 nest sites and found both annual and seasonal variation in barn owl diets. Microtus ochrogaster occurred most frequently (32.7%) and increased in the diet from 17.6 to 27.2 to 43.5% 1984-1986. M. ochrogaster and Perognathus hispidus annual frequencies were …
