Mountain Plover Sighted In Kimball County, Mary Clausen Dec 1990

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.

On 3 May …

Relationships Between Blood Parasites, Mating Success And Phenotypic Cues In Male Sage Grouse Centrocercus Urophasianus, Robert M. Gibson Jan 1990

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 Sep 1989

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 …

“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 Jun 1989

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 …

Habitat Use And Diet Analysis Of Breeding Common Barn Owls In Western Nebraska, Joseph A. Gubanyi M.S. Apr 1989

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 …


Williamson's Sapsucker In Omaha, Barbara L. Wilson Mar 1989

Williamson's Sapsucker In Omaha, Barbara L. Wilson

Nebraska Bird Review

On 13 May 1988 Dr. J. J. Baumel discovered a male Williamson's Sapsucker (Sphyrapicus thyroideus) lying dead below an elevated, glassed-in walkway between buildings on Creighton University's campus in downtown Omaha, Nebraska. The bird, beautiful in breeding plumage, was largely black from its awl-shaped bill to its stiff, acuminate central tail feathers. There was a white line beginning at the base of the lower mandible and extending over the face, while another ran back from the eye. The white wing coverts formed a broad white line on the wing. Also, there were white tips on the tertials, while …

Helminth Parasites Of Northern Spotted Owls (Strix Occidentalis Caurina) From Oregon, Eric P. Hoberg, G. S. Miller, E. Wallner-Pendleton, O. R. Hedstrom Jan 1989

Helminth Parasites Of Northern Spotted Owls (Strix Occidentalis Caurina) From Oregon, Eric P. Hoberg, G. S. Miller, E. Wallner-Pendleton, O. R. Hedstrom

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Helminth parasites are reported for the first time from northern spotted owls. Seventyone percent of a sample of Strix occidentalis caurina from western Oregon was infected. Nematodes (Porrocaecum depressum, Capillaria falconis, Microtetrameres sp. and Synhimantus hamatus) were the most prevalent parasites although cestodes (Paruterina rauschi) and acanthocephalans (Centrorhynchus conspectus) were also represented. There was an association between components of this helminth fauna and the diet of spotted owls which is dominated by small rodents. The occurrence of P. rauschi rather than P. candelabraria in this geographic region and host-species may provide additional …


Social Behavior Of North American Owls, Paul A. Johnsgard Jan 1989

Social Behavior Of North American Owls, Paul A. Johnsgard

Paul Johnsgard Collection

Social behaviors in animals include a very wide range of interindividual communications, both within and between species. They include such rather generalized social responses as social flocking or roosting behavior, as well as much more individualized and complex interactions such as courtship, aggression, and parental behaviors. Regardless of their complexity, social interactions involve some level of communication or the transmission and interpretation of social signals. These signals can be transmitted in any of several sensory channels, which in owls are most likely to include visual, acoustic, and tactile modes of communication.

Most and perhaps all owls show distinctive postures when …
