A 2009 Supplement To Birds Of The Rocky Mountains, Paul A. Johnsgard Nov 2009

A 2009 Supplement To Birds Of The Rocky Mountains, Paul A. Johnsgard

Birds of the Rocky Mountains by Paul A. Johnsgard

More than 20 years have elapsed since the publication of Birds of the Rocky Mountains, and many changes have occurred in that region’s ecology and bird life. There has also been a marked increase in recreational bird-watching, and an associated need for informative regional references on where and when to look for rare or especially appealing birds. As a result, an updating of the text seemed appropriate, especially as to the species accounts and the technical literature. The following update includes all those species that have undergone changes in their vernacular or Latin names, have had important changes in ranges, …

Birds Of The Rocky Mountains—Introduction, Paul A. Johnsgard

Birds of the Rocky Mountains by Paul A. Johnsgard

The Rocky Mountains represent the longest and in general the highest of the North American mountain ranges, extending for nearly two thousand miles from their origins in Alaska and northwestern Canada southward to their terminus in New Mexico, and forming the continental divide for this entire length. As such, these mountains have provided a convenient corridor for northward and southward movement of both plants and animal life, but on the other hand have produced important barriers to eastern and western plant and animal movements. These effects result nat only from their height and physical nature, but also from their manifold …

Behavior Of Buff-Breasted Sandpipers (Tryngites Subruficollis) During Migratory Stopover In Agricultural Fields, John P. Mccarty, Joel G. Jorgensen, Lareesa Wolfenbarger Nov 2009

Behavior Of Buff-Breasted Sandpipers (Tryngites Subruficollis) During Migratory Stopover In Agricultural Fields, John P. Mccarty, Joel G. Jorgensen, Lareesa Wolfenbarger

Nebraska Game and Parks Commission: Staff Research Publications

Background: Understanding the behavior of birds in agricultural habitats can be the first step in evaluating the conservation implications of birds’ use of landscapes shaped by modern agriculture. The existence and magnitude of risk from agricultural practices and the quality of resources agricultural lands provide will be determined largely by how birds use these habitats. Buff-breasted Sandpipers (Tryngites subruficollis) are a species of conservation concern. During spring migration large numbers of Buff-breasted Sandpipers stopover in row crop fields in the Rainwater Basin region of Nebraska. We used behavioral observations as a first step in evaluating how Buff-breasted Sandpipers …


Birds Of The Great Plains: Breeding Species And Their Distribution: New Expanded Edition (2009), Paul A. Johnsgard Oct 2009

Birds Of The Great Plains: Breeding Species And Their Distribution: New Expanded Edition (2009), Paul A. Johnsgard

Birds of the Great Plains (Revised Edition, 2009) by Paul Johnsgard

This book is the first to describe systematically all of the species of birds known to have bred or to breed at present in the Great Plains, a major ecological unit that encompasses all or part of part of eleven states: North Dakota, South Dakota, Minnesota, Iowa, Nebraska, Colorado, Kansas, Missouri, Oklahoma, New Mexico, and Texas. Although the original Great Plains ecosystem—the grassland biome—has been greatly altered by modem agriculture, remnants still exist in national and state parks, grasslands, and refuges, as well as in rural cemeteries, railroad rights-of-way, and small nature reserves. These areas support populations of nearly all …


It's Not Too Late For The Harpy Eagle (Harpia Harpyja): High Levels Of Genetic Diversity And Differentiation Can Fuel Conservation Programs, Heather R. Lerner, Jeff A. Johnson, Alec R. Lindsay Ph. D., Lloyd F. Kiff, David P. Mindell Oct 2009

It's Not Too Late For The Harpy Eagle (Harpia Harpyja): High Levels Of Genetic Diversity And Differentiation Can Fuel Conservation Programs, Heather R. Lerner, Jeff A. Johnson, Alec R. Lindsay Ph. D., Lloyd F. Kiff, David P. Mindell

Faculty Works

Background: The harpy eagle (Harpia harpyja) is the largest Neotropical bird of prey and is threatened by human persecution and habitat loss and fragmentation. Current conservation strategies include local education, captive rearing and reintroduction, and protection or creation of trans-national habitat blocks and corridors. Baseline genetic data prior to reintroduction of captive-bred stock is essential for guiding such efforts but has not been gathered previously.

Methodology/Findings: We assessed levels of genetic diversity, population structure and demographic history for harpy eagles using samples collected throughout a large portion of their geographic distribution in Central America (n = 32) and South America …

Birds Of The Great Plains: Three Decades Of Change In Great Plains Birds: A 2009 Supplement To The Birds Of The Great Plains: Breeding Species And Their Distribution, Paul A. Johnsgard

Birds of the Great Plains (Revised Edition, 2009) by Paul Johnsgard

Since the 1979 publication of this book much has been learned of breeding bird distributions in North America, largely as a result of the national Breeding Bird Surveys that were initiated in the 1960s and have continued to the present (Sauer, Hines and Fallon, 2008). From these studies long-term regional average densities of breeding birds have been deduced and national maps generated (Patuxent Wildlife Research Center. 2003). There have also been several state-wide studies on breeding birds of the Great Plains, as represented by breeding bird atlases for South Dakota (Peterson, 1995), Nebraska (Mollhoff, 2001), Kansas (Busby and Zimmerman, 2001), …

Long-Tailed Jaegers In Western Nebraska, Stephen J. Dinsmore Sep 2009

Long-Tailed Jaegers In Western Nebraska, Stephen J. Dinsmore

Nebraska Bird Review

The Long-tailed Jaeger is an accidental migrant in Nebraska with just one accepted record through the mid-1990s. Based on records from adjacent states, especially Colorado (Andrews and Righter 1992) and Wyoming (Faulkner 2010), the species is probably more frequent than these records indicate, and its status is further complicated by possible confusion with Pomarine and Parasitic jaegers. In this article I report details of four records of Long-tailed Jaegers in western Nebraska and comment on the species' identification and status in the state.

Summer Field Report, June-July 2009, W. Ross Silcock

Nebraska Bird Review

This was an interesting summer, with range expansions of multiple species continuing in all directions, but predominantly northward. Exceptions to the northward trend were Trumpeter Swan, which bred south of its usual western Sandhills range, and Sedge Wren, which may be occurring in June in northeast Nebraska in greater numbers. Moving eastward are Western Wood-Pewee, which now overlaps with westward-moving Eastern Wood-Pewee in Lincoln Co, Cordilleran Flycatcher in the Pine Ridge, and Lesser Goldfinch in the west. Song Sparrow is also expanding south and west. No fewer than 16 species are moving north and/or northwestward. Several species were seen more …

Song Of The North Wind: A Story Of The Snow Goose, Paul A. Johnsgard, Paul Geraghty Aug 2009

Song Of The North Wind: A Story Of The Snow Goose, Paul A. Johnsgard, Paul Geraghty

Papers in Ornithology

As a boy in North Dakota, Paul Johnsgard measured his winters, not by conventional time units, but in the days it took for the snow geese to return from their wintering grounds to Lake Traverse. In early April, with hip boots, camera, and binoculars, he awaited the arrival of the first flocks from the Gulf of Mexico. Johnsgard was not alone in admiring the beauty and strength of the snow goose. For centuries this bird has signified the passing seasons to the Indians—its white feathers a symbol of the breath of life and a reminder of the roles the birds …

Fecal-Sac Ingestion By Spotted Towhees, Jenny E. Mckay, Michael T. Murphy, Sarah Bartos Smith, Jennifer K. Richardson Aug 2009

Fecal-Sac Ingestion By Spotted Towhees, Jenny E. Mckay, Michael T. Murphy, Sarah Bartos Smith, Jennifer K. Richardson

Biology Faculty Publications and Presentations

Altricial nestlings encase excrement in fecal sacs that parents remove by either ingesting them or transporting them away from the nest. Ingestion may allow energetically or nutritionally deprived parents to recapture energy or nutrients that might be lost because of nestlings' inefficient digestion (the "parental-nutrition hypothesis"), but ingestion may also permit parents to avoid flights from the nest that interfere with parental care (e.g., brooding young; the "economic-disposal hypothesis"). We used a hypothetico-deductive approach to test the two hypotheses' ability to account for fecal-sac ingestion by the Spotted Towhee (Pipilo maculatus). We confirmed the parental-nutrition hypothesis' predictions that …


A Nebraska Bird-Finding Guide, Paul A. Johnsgard Aug 2009

A Nebraska Bird-Finding Guide, Paul A. Johnsgard

Papers in Ornithology

Persons living in Nebraska often feel that they are living in a cultural wasteland; its citizenry preoccupied with violent sports such as hunting and football. Yet many are unaware that they are actually residing in one of the prime locations in the entire world for observing and enjoying some of the most aesthetically appealing of all the world's biological attractions. The area around Kingsley Dam and Lake McConaughy, for example, is known to have attracted more than 330 bird species, including 104 breeders (plus 17 probable breeders) making it the third-most species-rich bird location in the interior U.S.A. (after Laguna …

Spring Field Report, March–May 2009, W. Ross Silcock Jun 2009

Spring Field Report, March–May 2009, W. Ross Silcock

Nebraska Bird Review

The most obvious pattern this spring was early arrivals, especially among the shorebirds. Dunlin arrived record early, and 5 other species were close to record early dates. However, warblers, sparrows, and buntings were pushing early dates and Brown-headed Cowbird was early in numbers.

Winter finches were scarce except for Pine Siskin, which was present in good numbers, although breeding evidence was nonexistent.

Glossy Ibis continued in numbers as did easterly Lazuli Buntings. Nesting was confirmed at a new location for Red-shouldered Hawk; this is currently the only known active site in the state.

It was a great spring for genuine …

Modeling Parasitism Rate And Parasitism Risk: An Illustration Using A Colonially Nesting Songbird, The Red-Winged Blackbird Agelaius Phoeniceus, Max Post Van Der Burg, Larkin A. Powell, Andrew J. Tyre May 2009

Modeling Parasitism Rate And Parasitism Risk: An Illustration Using A Colonially Nesting Songbird, The Red-Winged Blackbird Agelaius Phoeniceus, Max Post Van Der Burg, Larkin A. Powell, Andrew J. Tyre

School of Natural Resources: Faculty Publications

Ornithologists interested in the drivers of nest success and brood parasitism benefit from the development of new analytical approaches. One example is the development of so-called “log exposure” models for analyzing nest success. However, analyses of brood parasitism data have not kept pace with developments in nest success analyses. The standard approach uses logistic regression which does not account for multiple parasitism events, nor does it prevent bias from using observed proportions of parasitized nests. Likewise, logistic regression analyses do not capture fine scale temporal variation in parasitism. At first glance, it might be tempting to apply log exposure models …
