A Probable Nesting Of Clark's Nutcracker (Nucifraga Columbiana) In Nebraska,, Wayne Mollhoff

Nebraska Bird Review

This report provides details on the probable nesting of Clark's Nutcracker (Nucifraga columbiana) in Morrill, Scotts Bluff Co., Nebraska, in 1997. It also corrects an erroneous report of nesting in the Pine Ridge area of Nebraska (Silcock & Jorgensen 1997b).

A single Clark's Nutcracker was first noted corning to a suet feeder at the home of Ms. Edna C. Thomas in Morrill 8-9 Jan 1997. It came to the feeder at least weekly and was often seen daily. A second Clark's Nutcracker appeared during the second week of Feb. Initially, the bird already present was antagonistic towards it …


Black-Throated Sparrow Banded In Omaha, Nebraska, Ruth C. Green Dec 1997

Black-Throated Sparrow Banded In Omaha, Nebraska, Ruth C. Green

Nebraska Bird Review

On 20 December 1997, I banded a Black-throated Sparrow in the vicinity of 43rd and J Streets in South Omaha, Nebraska. The band number on this bird is 2120/83856. It was an AHY-Male and, according to the description given by James D. Rising in his book, A Guide to the Identification and Natural History of the Sparrows of the United States and Canada, it was of the subspecies Amphispiza b. bilineata. This is the smallest of the three races found in the united States and it is indigenous to central Texas. Besides the smaller size, the identifying field …

Fall Field Report, August-November 1997, W. Ross Silcock, Joel G. Jorgensen Dec 1997

Fall Field Report, August-November 1997, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

Notable this Fall was very heavy coverage of the Panhandle during Sep-Oct, which yielded several outstanding records (all, of course, pending NOURC approval). Incredible were first Panhandle records of Golden-winged, Chestnut-sided, Bay-breasted, and Prothonotary Warblers, 3rd record of Northern Waterthrush, and 4th record of Blackburnian Warbler. Philadelphia Vireo was found in the Panhandle for the 3rd time. Important also were 3 records of Hammond's Flycatcher, the 3rd-6th for the state, and likely a regular migrant, and 5 of Cassin's vireo, previously known only by 2 specimens. Finally, from the Panhandle, 4 reports of Blue-Gray Gnatcatcher may be changing the status …


Whooping Crane Sightings, August 1997-January 1998, Steven Anschutz Dec 1997

Whooping Crane Sightings, August 1997-January 1998, Steven Anschutz

Nebraska Bird Review

Cooperation throughout the Whooping Crane flyway continues to be excellent, and special thanks go out to each participant. Between 1977 and 1988, 132 juvenile birds were color-marked on the breeding grounds, and 40 were accounted for during the winter of 1997-98. Fourteen color-marked Whooping Cranes were observed during the fall migration. All sightings of color-marked birds are maintained at the Grand Island office. The importance of observers looking closely for the colored leg bands cannot be overemphasized.

Based on observations of the breeding grounds during the summer of 1997, about 192 Whooping Cranes were expected to arrive at the Aransas …


Notes On The Nesting Biology Of Pygmy Nuthatches In Nebraska, Wayne Mollhoff Dec 1997

Notes On The Nesting Biology Of Pygmy Nuthatches In Nebraska, Wayne Mollhoff

Nebraska Bird Review

Introduction

Pygmy Nuthatches (Sitta pygmaea) were considered to be no more than casual or rare winter visitors to the northwest part of Nebraska by previous investigators (Bruner et al. 1904; Swenk 1918; Haecker et al. 1945; Rapp et al. 1958, 1971). I. S. Trostler's earlier comment that the species was "a rare resident, breeds in Omaha" (Bruner 1896) was later felt to be in error, as evidenced by Bruner's later comment that it was, "A fall and winter visitor . . . not breeding in the state" (Bruner et al. 1904).

The first evidence of breeding was the …


The Brood-Rearing Habitat, Brood Home Range, And Fecundity Of The Snowy Plover (Charadrius Alexandrinus) In Coastal Southern Texas, Jeffery R. Rupert Dec 1997

The Brood-Rearing Habitat, Brood Home Range, And Fecundity Of The Snowy Plover (Charadrius Alexandrinus) In Coastal Southern Texas, Jeffery R. Rupert

Theses and Dissertations - UTB/UTPA

Habitat fragmentation has been shown to have negative effects on avian communities. I looked at the effects of corridor width and vegetation characteristics on nesting densities and breeding success of birds in the Lower Rio Grande Valley. There were definite trends in this study of increasing species richness and nesting densities with increasing corridor widths. Multiple regression revealed little correlation between tree density, diameter at breast height, tree height, canopy cover and ground cover with nesting density or nesting success. However, factors such as parasitism by the Bronzed Cowbird (Molothrus aeneus) and predation were much greater in narrower corridors. This …


Breeding Densities And Habitat Of Riparian Birds Along The Lower Rio Grande, Texas, Corinna Elizabeth Rupert Dec 1997

Breeding Densities And Habitat Of Riparian Birds Along The Lower Rio Grande, Texas, Corinna Elizabeth Rupert

Theses and Dissertations - UTB/UTPA

The breeding biology of Snowy Plovers (Charadrius alexanderinus) was studied at Laguna Atascosa National Wildlife Refuge in coastal southern Texas. During 1995 and 1996 nests were found most often in high sand flat habitat and less frequently in low sand flat. Nest sites were dominated by open flat but had more rocks, pebbles and debris than control sites. Only 24% of the clutches hatched, while 67% were eaten by predators and 9% were flooded. Forty-three percent of Snowy Plover nests were within Least Tern (Sterna antillarum) colonies and these nests had a significantly greater chance of hatching than nests placed …


Competitive Interactions Among Symbiotic Fungi Of The Southern Pine Beetle, Kier D. Klepzig, Richard T. Wilkens Nov 1997

Competitive Interactions Among Symbiotic Fungi Of The Southern Pine Beetle, Kier D. Klepzig, Richard T. Wilkens

Dartmouth Scholarship

The southern pine beetle, a damaging pest of conifers, is intimately linked to three symbiotic fungi. Two fungi, Ceratocystiopsis ranaculosus and Entomocorticium sp. A, are transported within specialized structures (mycangia) in the beetle exoskeleton and are mutualists of the beetle. A third fungus, Ophiostoma minus, is transported externally on the beetle exoskeleton (phoretically) and is an antagonist of the beetle. This study examined competitive interactions among these three fungi. The results of de Wit replacement series and primary and secondary resource capture assays with these fungi provide strong evidence for differential competition between the phoretic and mycangial fungi. O. minus …


Postnatal Observations Of Behavioral Patterns Within The Social Organization Of Captive Bottlenose Dolphins (Tursiops Truncatus), Stacey R. Hanson Nov 1997

Postnatal Observations Of Behavioral Patterns Within The Social Organization Of Captive Bottlenose Dolphins (Tursiops Truncatus), Stacey R. Hanson

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Mirage Dolphin Environment opened in 1991. The Mirage has eight Atlantic Bottlenose dolphins. Four of these dolphins were relocated to the facility from other facilities that were either overcrowded or shutting down. The other four were born at the Mirage. The purpose and intent of the Mirage Dolphin Environment is to provide a nurturing environment for the dolphins and to educate the public about marine mammals and their ecosystems. The increased awareness associated with education will hopefully encourage public support for efforts to conserve and protect marine mammals and their environment.


Egg Removal By Brown-Headed Cowbirds: A Field Test Of The Host Incubation Efficiency Hypothesis, Douglas Wood, Eric Bollinger Nov 1997

Egg Removal By Brown-Headed Cowbirds: A Field Test Of The Host Incubation Efficiency Hypothesis, Douglas Wood, Eric Bollinger

Faculty Research & Creative Activity

Brown-headed Cowbirds (Molothrus ater) often remove host eggs, usually to the detriment of the host's reproductive success. We tested the hypothesis that host egg size and number influence the incubation efficiency of a parasitic egg. A single House Sparrow (Passer domesticus) or Brown-headed Cowbird egg was placed in each host nest (addition), and in some nests a host egg was removed as well (addition/removal). Hatching success and incubation length were measured to determine whether host-egg removal conferred an advantage in incubation efficiency compared to simple addition of a parasitic egg. Redwinged Blackbirds (Agelaius phoeniceus) and Chipping Sparrows (Spizella passerina) served …

Management Options For Pilbara Demersal Line Fishing, Gaye Looby Nov 1997

Management Options For Pilbara Demersal Line Fishing, Gaye Looby

Fisheries Management Papers

Fisheries Western Australia licensing arrangements allow all vessels with an unrestircted fishing boat licence ('wetline licence') to take scalefish throughout the State. These arrangements have led to a high level of excess capacity in the licensed 'wetline' fishing fleet to exploit the scalefish resources. The declaration of the Kimberley Interim Line Fishery and forthcoming declaration the Northern Demersal Scalefish Fishery have resolved this problem for the Kimberley waters. However, the high level of excss capacity in the 'wetline' fleet to exploit the waters of the Pilbara remains a problem Preview access and develop a management plan for the Pilbara demersal …

Whole Body I=In Vivo Vascular Compliance In Two Amphibians, Bufo Marinus And Rana Cate, Todd Micheal Hoagland Oct 1997

Whole Body I=In Vivo Vascular Compliance In Two Amphibians, Bufo Marinus And Rana Cate, Todd Micheal Hoagland

Dissertations and Theses

The mean circulatory filling pressure (MCFP), vascular compliance (C) and unstressed volume (USV) were measured in Bufo marinus and Rana catesbeiana, using an in vivo preparation. Capacitance curves were constructed by varying total vascular volume and then measuring MCFP. These capacitance curves enable the extrapolation of USV and the measurement of vascular compliance. The MCFP, C, and USV were 8.6 ± 0.2 (mmHg), 3.7 (ml· mmHg-1 · kg- 1 ) and 2.5 (ml), respectively, in B. marinus. The MCFP, C, and USV were 9.5 ± 0.1 (mmHg), 2.2 (ml· mmHg-1 · kg- 1 ) and 14.2 (ml), respectively, …

Terrestrial Natural Communities Of Nebraska - Version I, Gerry Steinauer, Steven B. Rolfsmeier

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The Nebraska Natural Heritage Program has been collecting information and data including published literature, field observations and vegetation plot data over the last 10 years of development of Nebraska’s natural community classification. The classification contains 27 wetland and 36 upland communities including forest, woodland, shrubland, herbaceous, and sparsely vegetated (e.g. rock outcrop) types. The community types were distinguished primarily on plant species composition and to a lesser extent on soils, hydrology and geographic location. The classification contains descriptions of each community type that include dominant species, soils, range, and other ecological information. The classification is designed to be flexible enough …


Vocal Response Of Piglets To Weaning: Effect Of Piglet Age, Daniel M. Weary, David Fraser Oct 1997

Vocal Response Of Piglets To Weaning: Effect Of Piglet Age, Daniel M. Weary, David Fraser

Ontogeny Collection

Piglets vocalize a great deal during the first few days after weaning. The aim of this experiment was to determine if the calls given by piglets vary in response to one factor thought to influence post-weaning adaptation: weaning age. In 22 litters, each containing a minimum of 9 piglets, 3 piglets were weaned under identical conditions at 3, 4 and 5 weeks of age. Vocalizations and weight gain were monitored for the week after weaning. The number of calls produced by piglets of all three ages declined from an average of 8.2 calls/min per piglet on the day of weaning …

Survey Of Mollusks Of The Niobrara River: Final Report, Patricia W. Freeman, Keith Perkins Sep 1997

Survey Of Mollusks Of The Niobrara River: Final Report, Patricia W. Freeman, Keith Perkins

School of Natural Resources: Faculty Publications

We surveyed the mollusks of the Niobrara River in Nebraska from 1992–1996. We found two species of unionid clams and ten species of snails that either must live in water or near water. Both clams and snails are poorly sampled in the state, however we attribute the low number of species of unionid clams in the Niobrara to its cold, fast flow and rocky bottom. In contrast, the Platte River is slower moving with a muddy bottom and has at least 11 species of unionid clams. Each species has been mapped with latitude/longitude coordinates. Specimens have been curated and are …

Two Hybrid Diving Ducks At Cunningham Lake, Douglas County, Joel G. Jorgensen Sep 1997

Two Hybrid Diving Ducks At Cunningham Lake, Douglas County, Joel G. Jorgensen

Nebraska Bird Review

During the spring of 1997 I had the opportunity to observe and study two apparent hybrid diving ducks at Glenn Cunningham Lake, Douglas County. Both birds appeared to be mature males in breeding plumage. One bird was a suspected Redhead x Canvasback hybrid and the other was a suspected Common Goldeneye x Hooded Merganser hybrid. Sibley (1994) states that both hybrid combinations occur "occasionally."
