Spring Field Report, March 2011 To May 2011, W. Ross Silcock

Nebraska Bird Review

There was a nice mix of interesting phenomena this spring, notably a big influx of migrant warblers. Species that are normally uncommon were reported in good numbers, 30 or more each: Chestnut-sided, Magnolia, Blackburnian, Palm, and Northern Waterthrush, and species that normally occur in very low numbers approached double digits: Blue-winged, Golden-winged, Cape May, and Baybreasted. Southeastern species continue to expand in se. Nebraska, notably Cerulean and Kentucky Warblers and Summer Tanager. A few rarities showed up, most spectacular an alternate-plumaged female Red Phalarope, the first such record for Nebraska, which was captured on video by Nebraska Non-Game TV. Other …

High Species Count At Annual Sarpy County Spring Bird Count, Clem Klaphake 2011 University of Nebraska - Lincoln

High Species Count At Annual Sarpy County Spring Bird Count, Clem Klaphake

Nebraska Bird Review

On May 14, 2011, participants in the Annual Sarpy County Spring Bird Count tallied 174 species, besting the previous high count of 143 (in 2006 and 2010) by 31 species. There were a few more counters this year than in most previous years, but it was just a good year for many families of birds. There were 28 warbler species seen (previous high was 23 in 2008). Also found were 4 terns, 9 flycatchers, 7 woodpeckers, 12 ducks, 14 shorebirds and 3 grebes. There are often unusual species that show up on the count, as illustrated by a Eurasian Wigeon …


An Ecological Study Of Peregrine Falcons (Falco Peregrinus) At Lake Mead National Recreation Area, 2006-2010, Joseph Graham Barnes 2011 University of Nevada, Las Vegas

An Ecological Study Of Peregrine Falcons (Falco Peregrinus) At Lake Mead National Recreation Area, 2006-2010, Joseph Graham Barnes

UNLV Theses, Dissertations, Professional Papers, and Capstones

Peregrine Falcons (Falco peregrinus) represent an encouraging conservation biology success story in North America during the twentieth century. Their distribution and population size suffered major restrictions after the initiation of widespread application of the synthetic pesticide dichloro-diphenyl-trichloroethane (DDT) within the U.S. in the 1940s. The species was federally listed as endangered in the U.S. in 1969 and was then delisted in 1999 after DDT was banned in 1972. Herein, I present my ecological research of peregrines within Lake Mead National Recreation Area (LMNRA), concentrating on the years 2006-2010. This thesis is comprised of two chapters. In the first chapter, I …

Nitric Oxide Synthesis By Chicken Macrophages Results In Coordinated Changes Of Multiple Arginine Transporters, Michael Moulds 2011 California Polytechnic State University, San Luis Obispo

Nitric Oxide Synthesis By Chicken Macrophages Results In Coordinated Changes Of Multiple Arginine Transporters, Michael Moulds

Master's Theses

Arginine transport is primarily mediated by the cationic amino acid transporters (CATs) in mammalian cells, but in aves the y+, b0,+ and B0,+ transport systems have also been observed. Arginine is the limiting catabolic substrate required for the production of nitric oxide (NO), a highly reactive compound that acts as a signaling molecule or killing compound. NO is synthesized by inducible nitric oxide synthase (iNOS) by macrophages for pathogen clearance. In mammals, CAT-2B is responsible for ARG import in the macrophage for NO synthesis, but the chicken CAT-2B isoform does not transport ARG. Therefore the objective …


Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen 2011 Eastern Illinois University

Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen

Great Plains Research: A Journal of Natural and Social Sciences

Over the past century, the interactions between agricultural land use and government cropland retirement programs have affected pheasant population change. Two government land retirement programs that returned croplands to grasslands, Soil Bank in the 1960s and the current Conservation Reserve Program (CRP), help to illustrate these connections. From 2007 to 2010, South Dakota lost 41% of its CRP lands and experienced an 18% decline in pheasants per mile. However, because of where CRP expirations have occurred and where pheasant populations are found, some regional variability is seen. Western South Dakota (Region 1) had an 80% increase in pheasants per mile …


High Speed Flight At Low Altitude: Hazard To Commercial Aviation ?, Paul F. Eschenfelder , Capt. 2011 Aviation Consultant, Spring, Texas

High Speed Flight At Low Altitude: Hazard To Commercial Aviation ?, Paul F. Eschenfelder , Capt.

Paul F. Eschenfelder

Commercial aircraft are capable of, and in fact, do, operate at high speed (>250 knots indicated airspeed [KIAS]) at low altitude (below 10,000’ above ground level) worldwide. Design, construction and certification standards for these aircraft were developed over 40 years ago. Since the development of these standards populations of large flocking birds have increased dramatically in many parts of the world. Yet neither design/construction standards nor operational practice have changed to reflect the new threat. Subsequent serious damage resulting from recent collisions indicates change is necessary. Since 2003, flight rules in Canada and the United States have been amended, …


Integrating Avian Radar Into The Aviation Operating Environment, Richard Sowden, Paul Eschenfelder 2011 Avian Aviation Consultants; Guelph, Ontario, Canada

Integrating Avian Radar Into The Aviation Operating Environment, Richard Sowden, Paul Eschenfelder

Paul F. Eschenfelder

Avian radar technology has matured to the point where robust data and analysis tools are now able to provide the aviation industry with high quality information to support bird strike risk mitigation activities. The aviation operating environment is dynamic and challenging with complex interactions between the primary bird strike risk mitigation stakeholders; airport operators, air traffic service providers and flight crews. The transfer of this proof of concept technology into a suite of tools that is integrated into the aviation industry requires the engagement and support of the user community in the next critical evolutionary step of this emerging technology. …

Winter Field Report, December 2010 To February 2011, W. Ross Silcock 2011 Nebraska Ornithologists' Union

Winter Field Report, December 2010 To February 2011, W. Ross Silcock

Nebraska Bird Review

This winter was pretty much a rerun of last, although perhaps not as severe; I could have used last winter's Introduction again. If there was an overall theme, it would be the widespread occurrences of species that would not be expected to linger into late December and January. Several species of waterbirds, notably Blue-winged Teal, scoters, Ruddy Duck, Common Loon, and Homed and Red-necked Grebes were in this category. Large numbers of Western Grebes were still at Lake McConaughy in early January, and surprisingly late individuals of Black-crowned Night-Heron and Plegadis ibis were located. Mourning Doves were in good numbers …

Book Review [Of Wild Birding Colorado: The Big Year Of 2010], W. Ross Silcock

Nebraska Bird Review

Nebraska birders might remember seeing reports posted to NEBirds a few years back by Cole Wild, a native Coloradan whose mother's family is from Nebraska. Cole took up birding at age 19, spurred by an earlier high school environmental science class that required identification of 100 species of birds. As with many of us, a brightly plumaged bird, in this case a Western Tanager, resulted in "the birdwatching gene" in Cole suddenly being "switched to the ON position." Soon after, Cole went on a "what the heck, I'll try it" field trip to see a Kelp Gull at Loveland Reservoir …


A Late-Season Breeding Record For The Summer Tanager In Nebraska, Eric C. Hopps 2011 University of Nebraska - Lincoln

A Late-Season Breeding Record For The Summer Tanager In Nebraska, Eric C. Hopps

Nebraska Bird Review

The breeding range of the Summer Tanager (Piranga rubra) is well documented and expands across the southern U.S. extending northward to New Jersey and west along and south of the Great Lakes to the eastern edge of the Great Plains (Terres 1991; Robinson 1996). In Nebraska the species is generally confined to the Lower Missouri and Platte River Valleys where it occurs locally (Sharpe et al. 2001). Because the species exists in relatively low numbers across southeastern Nebraska, there are few breeding and nesting records for the state. Fewer than 10 breeding records, including one historical account have …


2010–2011 Christmas Bird Counts, Don Paseka 2011 University of Nebraska - Lincoln

2010–2011 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Fourteen Christmas Bird Counts were held in Nebraska in the 2010–2011 season. The Branched Oak–Seward count was canceled due to weather, but in comparison to last year, the weather was generally dry, mild, and cooperative. Even though open water was limited, the species associated with water were well represented, resulting in the highest total number of species (149) ever, easily topping the previous high count of 138 in 2001. In all, 17 species set new high counts, 5 tied previous highs, and the amazing Brown-headed Nuthatches stayed in Lincoln and were counted for the first time in Nebraska.

Twelve species …

Book Review [Of The Stokes Field Guide To The Birds Of North America], Tim Hajda 2011 University of Nebraska - Lincoln

Book Review [Of The Stokes Field Guide To The Birds Of North America], Tim Hajda

Nebraska Bird Review

Don and Lillian Stokes are well known for their nature guides that cover a variety of subjects, from hummingbirds and beginner shorebird identification to reptiles and amphibians. Their original pair of Stokes Field Guide to Birds: Eastern Region and Western Region have remained popular among North American birders since their appearance in 1995. They were illustrated with photographs instead of the traditional paintings used in most field guides. The authors' latest book, The Stokes Guide to Birds of North America is essentially an entirely new and much improved version of these two guides. Instead of being split into two books, …
