Gray Flycatcher At Oliver Reservoir, Stephen J. Dinsmore, Loren Padelford, Babs Padelford Jan 2000

Gray Flycatcher At Oliver Reservoir, Stephen J. Dinsmore, Loren Padelford, Babs Padelford

Nebraska Bird Review

On 17 May 1999, we were birding near the main entrance of Oliver Reservoir State Recreation Area in Kimball County, Nebraska. At 8:05 a.m. we found a very gray empidonax flycatcher in the scattered trees south of the main entrance. After studying the bird for a few minutes, we concluded that the bird was a Gray Flycatcher. We studied and photographed the bird at close range until we left at 8:55 a.m.


A Summer Survey Of The Birds At Two Eastern Nebraska Wetlands, Kristine T. Phipps Jan 2000

A Summer Survey Of The Birds At Two Eastern Nebraska Wetlands, Kristine T. Phipps

Nebraska Bird Review

This study compares the avian species diversity at two eastern Nebraska wetlands that differ in their relative isolation from an urban environment. Birds were surveyed by the point Count method twice weekly at each site during June of 1998. Diversity was measured using species richness and species evenness. The percentage of bird species observed that depend on wetlands for breeding was also compared.

Results suggest that both species richness and evenness, as determined by the Shannon-Wiener index, were higher at the wetland located in a network of other marsh areas and agricultural land than at the suburban wetland. Immigration of …


The 1999·2000 Nebraska Christmas Bird Count, Stephen J. Dinsmore Jan 2000

The 1999·2000 Nebraska Christmas Bird Count, Stephen J. Dinsmore

Nebraska Bird Review

The 1999·2000 Christmas Bird Count (CBC) period included ten counts in Nebraska (Table 2). These counts reported a total of 133 species, a great total for so few counts. Counts were scattered statewide, but most effort was in the eastern half of the state where most of the birders are. The top count this year was Lake McConaughy, where the combination of several lingering rarities, excellent participation, and great count weather led to a new record Nebraska count of 101 species, breaking the old record of 87 species. Other excellent totals were 85 at Harlan County, 84 at Branched Oak-Seward, …

Nou Spring Count

Nebraska Bird Review

The NOU Spring meeting took place from May 19 to 21 in Chadron. Table 1 lists the 165 total species identified in five counties during this period.

A Red Pharlarope was reported in Box Butte Co. by Kathy larson. Details have been submitted to the Records Committee, and the species is not included in this table pending the committee's decision.

Reports for the following species are included in this list with the following comment suggested by W. Ross Silcock:, "No details on 10; rare in this part of NE": Northern Bobwhite, Short-billed Oowitcher, and Field Sparrow.


Spring Field Report, March To May 2000, W. Ross Silcock Jan 2000

Spring Field Report, March To May 2000, W. Ross Silcock

Nebraska Bird Review

This spring was a fairly normal, although I heard comments about warblers being rather tough to find. The reports did confirm that for many of the migrant northwoods species. There were a few rarities, none represented first state records, however. Foremost of these were White Ibis, Glossy Ibis, blue-morph Ross's Goos~, Common Crane, Band-tailed Pigeon, Hammond's Flycatcher, and Black-throated Gray Warbler. The following birds may join these, although each may have fatal flaws, at least in the eyes of the NOURC: Red Phalarope and Slaty-backed Gull. Other interesting sightings included a Mississippi Kite in Lincoln; Gray Partridges in Scotts Bluff …


Yellow-Billed Loon At Lake Mcconaughy, Stephen J. Dinsmore, Joel G. Jorgensen Jan 2000

Yellow-Billed Loon At Lake Mcconaughy, Stephen J. Dinsmore, Joel G. Jorgensen

Nebraska Bird Review

On 8 August 1998 we observed a Yellow-billed loon (Gavia adamsii) at lake McConaughy in Keith County, Nebraska. We arrived at the pull-off on the south end of the dam at 6:25 p.m. and soon spotted a distant loon off the dam. On the basis of the yellow bill, head pattern, and large size, we concluded the bird was a Yellow-billed loon. We studied the bird until 7:33 p.m. and again from 9:03-9:45 a.m. on 9 August. Compared to a Common loon, this bird was huge and large-headed. The neck was very thick with an almost puffy appearance. …


Mist Netting At Oliver State Recreation Area, Stephen J. Dinsmore Jan 2000

Mist Netting At Oliver State Recreation Area, Stephen J. Dinsmore

Nebraska Bird Review

During the fall 2000 migration, I decided to do some mist netting at Oliver State Recreation Area in Kimball County. My main emphasis was to document the occurrence of several species of Empidonax in western Nebraska. limited netting there in fall 1999 was not very successful, but I was more optimistic this year. With that in mind, I obtained the necessary federal and state permits and netted on four dates (26 August, 31 August, 7 September, and 20 September), each chosen to be immediately after the passage of a cold front.


Historic Birds Of Lincoln's Salt Basin Wetlands And Nine-Mile Prairie, Paul A. Johnsgard Jan 2000

Historic Birds Of Lincoln's Salt Basin Wetlands And Nine-Mile Prairie, Paul A. Johnsgard

Nebraska Bird Review

The changes that have occurred in the bird life of the Lincoln area during the past century must certainly be great, but we have little evidence to document this point. There is, however, an annotated bird list from 1900 for the salt basin wetlands of western Lincoln, an area then gradually being developed for recreational use. This list was published by J. S. Hunter in the Proceedings of the First Annual Meeting of the Nebraska Ornithologists' Union (1900, 18-21). At this time, the recently impounded but still saline lake was 2 to 3 feet deep, and it covered about two …


Book Review: Birds Of The Untamed West. The History Of Birdlife In Nebraska, 1750 To 1875 By James E. Ducey, W. Ross Silcock Jan 2000

Book Review: Birds Of The Untamed West. The History Of Birdlife In Nebraska, 1750 To 1875 By James E. Ducey, W. Ross Silcock

Nebraska Bird Review

Those with an interest in the birds of the Great Plains will be familiar with Jim Ducey's Nebraska Birds: Breeding Status and Distribution, published in 1988. I was amazed then by Jim's diligence in searching a wide range of sources and compiling an exhaustive list of Nebraska breeding records organized by county. Jim's new book, Birds of the Untamed West, reflects the same dogged pursuit of obscure sources unavailable to most of us and compilation of the results. If you expect such a compilation to be dry and boring, you will be pleasantly surprised, especially if you are …


A Century Of Breeding Birds In Nebraska, Jackie Canterbury, Paul A. Johnsgard Jan 2000

A Century Of Breeding Birds In Nebraska, Jackie Canterbury, Paul A. Johnsgard

Nebraska Bird Review

With the imminent publication of the Nebraska Breeding Bird Atlas and the turning of a new millennium, it is perhaps an appropriate time to survey the state of breeding birds in Nebraska. Wayne Mollhoft's summary of the N.O.U.'s Nebraska Breeding Birds Atlasing Project (Mollhoff, 2000) provides important data bases for the latter part of the past century, and the historic overview by James Ducey (1988) offers a useful basis for judging the breeding avifauna of Nebraska from about the beginning of the century. The Biological Resources Division of the U. S. Geological Survey's (WSGSBRD) annual Breeding Bird Survey data currently …


Fall Field Report, August-November, 2000, W. Ross Silcock Jan 2000

Fall Field Report, August-November, 2000, W. Ross Silcock

Nebraska Bird Review

This fall season was amazing, or as Stephen Dinsmore put it: ''The birding was simply spectacular in western Nebraska this fall," There was something for everyone, whether rarity-chasers, taxonomists, listers, or whatever. There were no fewer than four new species for the state list (pending NOURC approval, of course!), a total of 315 species reported, and fascinating information on western subspecies in the Panhandle.

Numbers of western migrants reached record levels, exemplified by fall totals of 53 Townsend's Warblers, 25 MacGillivray's Warblers, and 28 Western Tanagers. By contrast, eastern migrant warblers in the east were almost non-existent.

At L McConaughy, …


First Record Of An Arctic Tern For Nebraska, Stephen J. Dinsmore Jan 2000

First Record Of An Arctic Tern For Nebraska, Stephen J. Dinsmore

Nebraska Bird Review

On 20 September 2000, I arrived at Lake Minatare in Scotts Bluff County after the passage of a strong cold front the day before. At 11:36 a.m., I noticed two distant Sterna flying east of the lighthouse. Although the distance was great, I could see that one tern was a juvenile Forster's Tern while the other tern was clearly a different species. Even at a distance, I thought I could see a white cheek, a darker gray belly, and pale upperwings, all indications that the bird was an adult Arctic Tern. I then drove to the lighthouse and soon found …


Predation Rates On Real And Artificial Nests Of Grassland Birds, William B. Davison, Eric K. Bollinger Jan 2000

Predation Rates On Real And Artificial Nests Of Grassland Birds, William B. Davison, Eric K. Bollinger

Eric K. Bollinger

We estimated nesting success at real and artificial nests of grassland birds to test the influence of nest type, nest position, and egg size on predation rates. We distributed wicker nests and realistic woven-grass nests baited with a clay egg and either a Northern Bobwhite (Colinus virginianus) egg or a House Sparrow (Passer domesticus) egg in four grasslands that were part of the Conservation Reserve Program in east-central Illinois. Nesting success averaged 86.5% for 12 days of exposure for artificial nests. For real nests, nesting success was markedly lower, averaging 39% over the entire nesting cycle and 59% during approximately …

Growth And Performance Of Broiler Chicks During The Starter And Grower Phases In Phase-Feeding, L. Niki Loupe, Jason L. Emmert Jan 2000

Growth And Performance Of Broiler Chicks During The Starter And Grower Phases In Phase-Feeding, L. Niki Loupe, Jason L. Emmert

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

An experiment was conducted to evaluate the efficacy of a nutrition program referred to as “phase-feeding” (PF) over the first 6 weeks posthatching. Diets were formulated using amino acid recommendations from the National Research Council (NRC) (1994) or from linear regression equations generated from best estimates of lysine (Lys), sulfur amino acid (SAA), and threonine (Thr) requirements. Regression equations were used to predict weekly Lys, SAA, and Thr requirements for use in a PF regimen that involved lowering amino acid levels following each respective week of the experiment, resulting in six diets fed over the 6-week period. Over the entire …


Melanocortin-1-Receptor (Mcr-1) Gene Polymorphisms Associated With The Chicken E Locus Alleles, Andrew Ellett Jan 2000

Melanocortin-1-Receptor (Mcr-1) Gene Polymorphisms Associated With The Chicken E Locus Alleles, Andrew Ellett

Inquiry: The University of Arkansas Undergraduate Research Journal

The melanocortin 1-receptor (MCl-R) gene has been associated with E locus phenotypes in chickens. Variant alleles of the E locus are important for accurate down color sexing and also for the inhibition of unwanted tissue pigmentation in broilers. PCR (polymerase chain reaction) based tests for various replacement substitutions found in the published E allele sequences gave unexpected results when tested against known alleles of the E locus. To resolve these issues and gain a better understanding of how replacement substitutions in the MCl-R gene are affecting E locus phenotypes, a number of accessions of the e+, eb, wheaten ( ewh …


Lymphocyte Profiles In Blood And Tumors Of Arkansas Rous Sarcoma Regressor And Progressor Chickens, Brant Ward Jan 2000

Lymphocyte Profiles In Blood And Tumors Of Arkansas Rous Sarcoma Regressor And Progressor Chickens, Brant Ward

Inquiry: The University of Arkansas Undergraduate Research Journal

The Arkansas Rous Sarcoma Regressor (AR) and Progressor (AP) lines of chickens represent an excellent model to study immune responses to tumors. Both lines of chickens initially develop tumors when injected with Rous sarcoma viros (RSV) or with DNA coding for the RSV oncogene v-src (v-src DNA). AR chickens will eventually regress the tumors whereas AP chickens will allow the tumors to progress to a terminal stage. By using both v-src DNA and RSV for tumor induction, we were able to compare the immune response to tumor antigens alone and tumor antigens in combination with viral components, respectively. To study …


Reproductive Behavior Of The Emu, Reema A. Persad, Douglas James, Nicholas B. Anthony Jan 2000

Reproductive Behavior Of The Emu, Reema A. Persad, Douglas James, Nicholas B. Anthony

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Members of a flock of male and female emus were observed in an ethological experiment designed to investigate trends in reproductive behavior exhibited during the North American mating season, which lasts from October to mid-March. Observations were made at dawn, noon, and dusk from December 1999 to mid-March 2000, and the only behaviors that were consistently expressed during these times were pecking, strutting, exclusive, and male and female sexual activities (defined in text). Though statistical significance was found between male strutting behavior and female sexual activity in the December observation period, no overall significance or significance at other observation periods …
