Revised Checklist Of North American Mammals North Of Mexico, 1986, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways, Robert S. Hoffmann, Dale W. Rice, Clyde Jones Dec 1986

Revised Checklist Of North American Mammals North Of Mexico, 1986, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways, Robert S. Hoffmann, Dale W. Rice, Clyde Jones

University of Nebraska State Museum: Mammalogy Papers

As in previous lists, orders, families, and genera are listed in conventional phylogenetic sequence mostly following Hall (1981) but, in a departure from previous lists, species are entered alphabetically within each genus. This will facilitate use of the checklist by those unfamiliar with intrageneric taxonomy. Some assemblages are not well enough understood to create a meaningful hierarchy at the specific level.

Proximity Nesting: The Great Horned Owl And Red-Tailed Hawk, Steve Shupe Dec 1986

Proximity Nesting: The Great Horned Owl And Red-Tailed Hawk, Steve Shupe

Nebraska Bird Review

Introduction: Forty-two nests of the Great Horned Owl (Bubo virginianus) and 78 nests of the Red-tailed Hawk (Buteo jamaieensis) were surveyed during a three-year ecological study (1982–84). In 11 instances nests of the two species overlapped the hunting areas of the other. Home ranges, in which most hunting takes place, have been defined by various authors (Miller, 1930; Baumgartner, 1939; Hagar, 1967). For this study Hawks and Owls nesting within one-half mile of each other were compared. The proximity nesting of these two species seemed likely to increase the possibility of predation upon the young of …

Cassin’S Sparrow In Garden County, Thomas E. Labedz Dec 1986

Cassin’S Sparrow In Garden County, Thomas E. Labedz

Nebraska Bird Review

On 21 May 1986, while searching for evidence of breeding birds in atlas block 2G04 near Lisco, Garden County, Nebraska, I discovered a Cassin’s Sparrow (Aimophila cassinii). This sighting was at 5:20 PM Mountain Daylight Time, along the county road in the northeast corner of Section 11. I was driving slowly down the road and stopped to observe an odd sparrow. I nearly drove past, thinking it was another Grasshopper Sparrow (Ammodramus savannarum), which I had heard and seen all day. The sparrow, which appeared larger than a Grasshopper Sparrow, was perched on the low wire …

Bears and Men: A Gathering, William Mills, 108 pp., 9¼ x 9¼, Algonquin Books of Chapel Hill, Chapel Hill, NC, cloth $24. 95. The author’s pictures, mostly of polar bears, but with a few of seals, arctic fox, men and their machine, and two of Ptarmigan, are probably more important than the text, which describes a trip out from Churchill in a tundra buggy towing a dormitory accommodation, both supposedly (but not too) bear-proof. The trip was organized for those who were interested in photographing polar bears under relatively natural conditions. In the course of the narrative the author …


1986 Fall Field Day Dec 1986

1986 Fall Field Day

Nebraska Bird Review

The 1986 Fall Field Day was held at the 4-H Camp at Halsey National Forest on 4 and 5 October. The cloudy, rainy weather, which had been rather general over the state the previous few days, cleared up (the last rain at Halsey was late Friday night), and Saturday and Sunday were clear, which pleased the 51 who attended. Of the rare bird reports submitted, the Lesser Goldfinch, by Jim Minyard, was ranked first, and the Laughing Gull, by Paul and Karla Kaufman, the Prairie-Chickens at Omaha, by Douglas Fritz, and the King Rail, by Wayne Mollhoff, were ranked next. …

Avian Cholera In The Panhandle, 1985–1986, Stephen M. Kerr

Nebraska Bird Review

Between 28 November 1985 and 14 February 1986, over 2,500 waterfowl, 48 Wild Turkeys, and at least one Bald Eagle died due to avian cholera in an area from 5 miles west of Scottsbluff, Nebraska, to 5 miles west of Lingle, Wyoming.

On 28 November a severe snowstorm blanketed the North Platte River valley with 10 inches of snow and wind chills of –20°F. An estimated 50,000 Mallards were concentrated 5 miles west of Scottsbluff, at the headwaters of Spring Creek. The area consists of 2 small dredged channels, 10 feet wide and less than 3 feet deep, and surrounded …


California Gull In Keith County, Nebraska, Mark A. Brogie Dec 1986

California Gull In Keith County, Nebraska, Mark A. Brogie

Nebraska Bird Review

The status of the California Gull (Larus californicus) in Nebraska has undergone a series of changes in recent years. Rapp et al. (1958) makes no mention of this species for Nebraska, although one was collected 19 March 1933 in Lancaster County (Hudson 1933) and is now an axial skeleton #ZM11152 in the University of Nebraska State Museum (Bray et al. 1986). Johnsgard (1980) lists the species as an extremely rare migrant or vagrant in most of Nebraska, while Rasche (1982) designates it as casual in spring and summer and accidental in autumn in northwestern Nebraska and southwestern South …

Writing A Documentation, Barbara L. Wilson

Nebraska Bird Review

As the previous article makes clear, the written documentation helps birdwatchers communicate clearly about unusual sightings. Preparing the report can even add to the excitement of the event as one settles into a comfortable chair with the field notes and paper, chortling “Wait ‘til they read about this!” Then one relives the whole experience while organizing one’s thoughts for writing. Those field notes are an important part of the process, for they keep small but critical details accurate. Train yourself to take some kind of notebook or paper into the field, though in a pinch the margin of a field …

“On Our Nebraska Records," Revisited, Wayne J. Mollhoff

Nebraska Bird Review

At the second annual meeting of the NOU, Dr. Robert H. Wolcott, one of our founders, presented a paper titled “On Migration Records and On Our Nebraska Records” (Proc. NOU 2:69, 1901), which included a plea for better documentation. He said, in part, “These problems must be met and answered in a spirit of scientific accuracy, if our conclusions are to carry weight with those living outside our borders. We must know what we know and record only what we know we know. We must be open at all times to conviction, but at the same time we must …

Mortality Of White-Tailed Deer In Northeastern Minnesota, Michael E. Nelson, L. David Mech Oct 1986

Mortality Of White-Tailed Deer In Northeastern Minnesota, Michael E. Nelson, L. David Mech

USGS Northern Prairie Wildlife Research Center

Abstract: Two hundred nine white-tailed deer (Odocoileus virginianus) were radiotracked in the central Superior National Forest, Minnesota, from 1973 through winter 1983-84; 85 deaths were recorded. Annual survival was 0.31 for fawns (<1.0 years old), 0.80 for yearling (1.0-2.0 years old) females, 0.41 for yearling males, 0.79 for adult (≥2.0 years old) females, and 0.47 for adult males. Monthly survival rates were high from May through December (0.94-1.00), except for yearling (0.60) and adult (0.69) bucks during the November hunting season. Most mortality occurred from January through April when gray wolf (Canis lupus) predation was an important mortality source for all cohorts. Yearlings males were most vulnerable to hunting and adult males to wolf predation.


Eulimdana Rauschorum N. Sp., A Filarioid Nematode (Lemdaninae) From Larus Dominicanus In Antarctica, With Comments On Evolution And Biogeography, Eric P. Hoberg Oct 1986

Eulimdana Rauschorum N. Sp., A Filarioid Nematode (Lemdaninae) From Larus Dominicanus In Antarctica, With Comments On Evolution And Biogeography, Eric P. Hoberg

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

Eulimdana rauschorum n. sp. is described from southern black-backed gulls, Larus dominicanus Lichtenstein in Antarctica. The species is most similar to Eulimdana lari (Yamaguti, 1935) from Charadriiformes in the Holarctic. Males have spicules equal in length that are asymmetric in structure distally. There are 4-5 and 3-5 caudal papillae in rows to the right and left of the anus, and two small genital papillae at the posterolateral margin of the anus. Females have a variable number of prominent caudal papillae and large microfilariae (365 μm in length). The morphological similarities and host distribution of E. rauschorum and E. lari suggest …

Whooping Cranes In Blaine County, Wayne J. Mollhoff

Nebraska Bird Review

On 7 April 1986 John Manning, of Norfolk, and I observed a pair of Whooping Cranes (Grus americana) in southeastern Blaine County, about 20 miles west of Taylor. I was notified by a local rancher, who found them while feeding his cattle that morning. John and I were guided to where the birds were feeding in a field. We observed them from about 1400 to 1500 hours as they fed leisurely. About 1500 hours they took off and flew out of sight, heading toward the Middle Loup River. They were found again in the same field about 1745 …


Habitat Selection And Movement Patterns In Sandhills Rodents, Cliff A. Lemen, Patricia W. Freeman Sep 1986

Habitat Selection And Movement Patterns In Sandhills Rodents, Cliff A. Lemen, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

Using fluorescent pigments, we were able to gather accurate information about the use of habitat and movement patterns of small nocturnal rodents. Use of habitat is strongly affected by the patchiness of vegetation of the sandhills. Microtus ochrogaster occupies the dense grass, Dipodomys ordii occupies the open sandy area, and Perognathus hispidus and P. flavescens occupy a mixed grass-forb zone. Advantages of the fluorescent method over more traditional methods of determining habitat use are presented. There are significant differences in the trails of species at the fine 10-cm scale, but these differences disappear at a larger 3-m scale. The significance …


Factors Influencing Best Annual Racing Time In Finnish Horses, M. Ojala, L. Dale Van Vleck, R. L. Quaas Aug 1986

Factors Influencing Best Annual Racing Time In Finnish Horses, M. Ojala, L. Dale Van Vleck, R. L. Quaas

Department of Animal Science: Faculty Publications

The fixed effects of year of race, season of race, sex, method of start, annual number of starts, length of race and racetrack were evaluated on best annual racing time in Finnish Horses. Data included 1,378 records for 554 horses by 206 sires. Five models were assumed within the age groups from 3 to 6 yr. The annual number of starts, method of start and season of race effects were interrelated. An increase in number of starts was associated with considerable improvement in a horse's best annual racing time. Records should not, however, be adjusted for effect of annual number …


Lambing Performance Of Morlam And Dorset Ewes Under Accelerated Lambing Systems, L. C. Iniguez, R. L. Quaas, L. Dale Van Vleck Jul 1986

Lambing Performance Of Morlam And Dorset Ewes Under Accelerated Lambing Systems, L. C. Iniguez, R. L. Quaas, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Two accelerated lambing systems, Morlam using Morlam sheep (USDA, Beltsville 1966 to 1975) and Carnal using Dorset ewes (Cornell 1978 to 1981), were evaluated for first lambing ages, interlambing intervals and conception probabilities. Morlam ewes were continuously exposed to rams over the year, while Carnal Dorset ewes were exposed every other month. Morlam lambs were mated as early as 367 d of age and Carnal Dorset lambs as early as 340 d. Early lambing was associated with higher rates of perinatal mortality (P>.05) and smaller litter size (P<.O1). Lambing years among Morlam ewes and season of birth of Carnal Dorset ewes influenced (P<.01) their first lambing ages. Lambing intervals averaged 293 and 303 d among Morlam and Carnal Dorset ewes, respectively. Age at first lambing and season in which the previous lambing occurred with influential factors (P<.01) on lambing intervals of Morlam ewes; longer intervals resulted when ewe lambs were mated at early ages (<12 mo), and when the previous lambing occurred in winter. Estimates of conditional probabilities of conception by month given the occurrence of estrus, reflected seasonal changes in both systems. The overall probability of conception for the Morlain system (P=.16) was relatively higher than that for the Carnal Dorset system (P=.14); numbers of lambings per ewe per yr were 1.28 and 1.21, respectively. Estimates of heritability for age at first lambing, lambing interval and conception probability were. 31, .06 and .30, respectively.


Relationship Between Snow Depth And Gray Wolf Predation On White-Tailed Deer, Michael E. Nelson, L. David Mech Jul 1986

Relationship Between Snow Depth And Gray Wolf Predation On White-Tailed Deer, Michael E. Nelson, L. David Mech

USGS Northern Prairie Wildlife Research Center

Abstract: Survival of 203 yearling and adult white-tailed deer (Odocoileus virginianus) was monitored for 23,441 deer days from January through April 1975-85 in northeastern Minnesota. Gray wolf (Canis lupus)predation was the primary mortality cause, and from year to year during this period, the mean predation rate ranged from 0.00 to 0.29. The sum of weekly snow depths/month explained 51% of the variation in annual wolf predation rate, with the highest predation during the deepest snow.


The Incidence Of Cryptosporidial Infections In Nebraska Dairy Calves, Douglas Lee Varner Jul 1986

The Incidence Of Cryptosporidial Infections In Nebraska Dairy Calves, Douglas Lee Varner

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Within the last decade a new etiologic agent has been identified as a possible cause of diarrhea in humans and domestic animals—that being the protozoan parasite Cryptosporidium. The purpose of this study was to determine the incidence and distribution of Cryptosporidium in the state of Nebraska, to determine if Cryptosporidium occurs more frequently in association with other enteropathogens and to determine about the relation of scouring in the calves to infection with Cryptosporidium. A total of 620 fecal samples from 334 dairy calves from 71 herds in Nebraska were examined for cyptosporidial oocysts using the Sheather’s sugar flotation …
