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 …
A Reclassification Of The Genera Of Scolytidae (Coleoptera), Stephen L. Wood
A Reclassification Of The Genera Of Scolytidae (Coleoptera), Stephen L. Wood
Great Basin Naturalist Memoirs
A taxonomic revision of the genera of Scolytidae (Coleoptera) in the world fauna is presented. Included are 215 valid genera and 273 invalid generic and subgeneric names. The type-species for each genus-group name was examined, including the type-specimen of the type-species in those taxa where a holotype, lectotype, or neotype has been designated—with the exception of four contemporary genera, the type-series of which are lost, and six fossil genera for which no effort was made to locate the types. Taxonomic keys to the families of the Curculionoidea, and to the subfamilies, tribes, and genera of Scolytidae are presented. Descriptions and …

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
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 …

Whooping Crane Roost Site Characteristics On The Platte River, Buffalo County, Nebraska, Gary R. Lingle, Kenneth J. Strom, Jerry W. Ziewitz
Nebraska Bird Review
Whooping Crane (Grus americana) use of the Platte River in Nebraska has been a controversial topic, especially in the last decade. Pressures from water development interests seeking Platte River water conflict with the needs of wildlife and interests from the conservation community. Between spring 1942 and fall 1984 there were 13 confirmed Whooping Crane sightings on or near the Platte River (US Fish and Wildlife Service, 1985). Lingle et al. (1984) described physical characteristics of a Platte River roost site used in 1983. This report describes the physical characteristics of the most recent known roost site on the …

Mottled Duck In Nebraska, W. Ross Silcock, Tanya Bray, Babs Padelford
Nebraska Bird Review
The two major US populations of Mottled Duck occur in Florida and along the Gulf Coast in Louisiana and Texas, with local breeding inland to “southeast Colorado, western Kansas, Oklahoma (rarely), and northeast Texas” (AOU Checklist of North American Birds, Sixth Edition, 1983). Palmer (Handbook of North American Birds, Vol. 2, 1976) notes that Mottled Duck bred in 1963 at Cheyenne Bottoms, Kansas, and that some individuals occur inland beyond the usual breeding range during the post-breeding period. Presumably these inland. records pertain to birds from the Texas-Louisiana population, as the Florida birds are generally considered nonmigratory. …

Descriptive Ethology And Activity Patterns Of Black-Footed Ferrets, Tim W. Clark, Louise Richardson, Steven C. Forrest, Denise E. Casey, Thomas M. Campbell Iii
Great Basin Naturalist Memoirs
Aspects of the aboveground ethology and activity patterns of the black-footed ferrets (Mustela nigipes) are described for a population in northwestern Wyoming as a first step in building a descriptive ethogram and quantification of activity patterns. We observed at least 237 individual ferrets for 208 hr on 441 occasions from 2 December 1981 through 25 September 1984. Mainenance behaviors (locomotion, alert, grooming, and sunning, defecation and urination, digging, and predation) and social behavior (reproduction, ontogeny, maternal, play, agonistic) are described as well as some ferret-human interactions. Ferret vocalizations are subjectively described. We located ferrets during most months including …

Great Basin Naturalist Memoirs
The black-footed ferret (Mustela nigripes) occupied area lies in the western Big Horn Basin, Park County, Wyoming. Cody, a nearby town, shows a record high temperature of 40.5 C and a low of -43.3 C, with 173 days each year below 0 C. Area geology is dominated by Absaroka volcanics. Soils are shallow (0.5 m) and underlain by unconsolidated gravels; well-drained, medium-textured clay-loams (ca 1 m in depth); or clays derived from shale parent materials. Vegetation is characterized by a wheatgrass-needlegrass shrubsteppe type (Agropyron/Stipa/Artemisia). Prior to white settlement, the area hosted a diverse large mammal community. …
The Diet Of The Gopher Tortoise, Gopherus Polyphemus, In A Sandhill Habitat In Central Florida, Laurie Ann Macdonald
The Diet Of The Gopher Tortoise, Gopherus Polyphemus, In A Sandhill Habitat In Central Florida, Laurie Ann Macdonald
USF Tampa Graduate Theses and Dissertations
Scat analysis and foraging observations were used to determine the diet of a gopher tortoise, Gopherus polyphemus, population in a sandhill community in west central Florida. Live vegetation was assessed to determine plant availability. The bulk of the gopher tortoise diet was composed of the dominant plant species in the habitat while the tortoises were selective with respect to most plant genera. Tortoises ingested many plant taxa with Poaceae, Asteraceae, Fabaceae, Pinaceae and Fagaceae being the most frequent components of the diet. Sixty-eight genera from 26 families were identified in the tortoise diet. In the scat the most common …
Variations In Radial Maze Performance Under Different Levels Of Food And Water Deprivation, Robert H.I. Dale, William A. Roberts
Variations In Radial Maze Performance Under Different Levels Of Food And Water Deprivation, Robert H.I. Dale, William A. Roberts
Scholarship and Professional Work - LAS
Four groups of rats were tested on an eight-arm radial maze under a free-choice procedure. The subjects were maintained at either 80% or 100% of their preexperimental free-feeding weights through restricted access to either food or water. Water-deprived subjects received water in the maze; food-deprived subjects received food. Water-deprived subjects learned the task faster than food-deprived subjects. The four groups developed different response patterns. These were measured by the mean transition size, the average angular distance (in 45° units) between consecutively chosen arms. Rats foraging for food and water developed different search strategies, with water-deprived subjects exhibiting lower mean transition …
Hybrid Bluebird Update, Barbara L. Wilson, Jim Minyard, Hope Minyard
Hybrid Bluebird Update, Barbara L. Wilson, Jim Minyard, Hope Minyard
Nebraska Bird Review
The female Mountain Bluebird and male Eastern x Mountain Bluebird nesting in Dawes Co. (NBR 53: 67) successfully fledged two broods, each with four young, in the summer of 1985. Young from the first nesting fledged in the last week of June. About 1 July the parents renested. Since the pair was observed copulating, it is highly probable that the hybrid male was the father of the young to be raised.
In mid-July the eggs hatched, but at this time the female became obviously ill. She sat on a fence with feathers ruffled and did not feed the young. …
