The Feathers Of Winter, Paul A. Johnsgard
The Feathers Of Winter, Paul A. Johnsgard
Paul Johnsgard Collection
For many Nebraska birders, the last big event of the year is the Audubon Christmas Bird Count, which is held annually during the last week of December. It is an occasion to join with friends in a day out to try see as many species as possible in a single day. More importantly, it provides a database that, combined with those of more than 50,000 other observers, provides a highly documented population sample of early-winter birds throughout North America, Latin America and the Caribbean region. The tradition began in 1900, and as of 2011 there have been 111 national counts. …

First Discovery Of A Four-Egg Clutch For Mountain Plover (Charadrius Montanus) In Nebraska, Bartholomew L. Bly, Travis Wooten
Nebraska Bird Review
On 27 May 2010, the first documented Mountain Plover nest in Nebraska to contain a clutch of four eggs was documented in a fallow strip of a dryland crop field in southern Kimball County. Mountain Plover typically have a clutch size of 3 eggs, though clutches with 1 and 2 eggs are observed in approximately 15% of nesting attempts (Knopf and Wunder 2006). Clutches with 4 eggs are rare and have been reported to occur in less than 1% of the population (Knopf and Wunder 2006). Five 4-egg clutches have been reported in Colorado and one in Montana (see Knopf …

First Documented Nebraska Sighting Of Brown-Headed Nuthatch (Sitta Pusilla), Larry Einemann
Nebraska Bird Review
Monday, November 8, 2010, was an unusually warm (upper 70s) autumn day for Lincoln, Nebraska, with no clouds and a wind from the southwest. I went to Holmes Lake Park in southeast Lincoln to scan for late migrating waterfowl and then to check the stand of conifers for the arrival of winter migrants. Around 11 A.M. I was attracted to a feeding group of six Black-capped Chickadees and three Red-breasted Nuthatches in the 30- to 40-year-old pines and Douglas firs north of Hyde Observatory. I noticed a differently patterned nuthatch in the group. I had seen a Pygmy Nuthatch several …

Fall Field Report, August–November 2011, W. Ross Silcock
Nebraska Bird Review
Overall, this fall migration was routine (waterfowl, warblers, sparrows), but there were a few unexpected highlights. The flooded Missouri River Valley provided habitat that led to some amazing fall counts: 3000 pelicans, 5700 coots, 338 American Golden-Plovers, and 1200 Pectoral Sandpipers. The 10,000 cormorants at Harlan County Reservoir may not have been affected by the Missouri River flooding, and were a record count also. While we're talking numbers, the martin roost in Omaha topped out at 50,000–55,000, and seasonal totals of 4 Red-necked Grebes and 15 Philadelphia Vireos for the state, 34 Mississippi Kites over Ogallala (it's often hard to …

Fall 2011 Bird Banding At Wildcat Hills Nature Center, Colin Woolley
Nebraska Bird Review
Rocky Mountain Bird Observatory has been operating a fall migration bird banding station at the Wildcat Hills Nature Center in Scotts Bluff Co. since 2007. In 2011, during our fifth year of banding, we captured a few new species, had new high totals for other species, and had a record number new high total of recaptures. Weather permitting, we banded on weekdays from August 31 through October 10 for five hours per day beginning soon after sunrise. We caught and banded 735 individual birds of 32 species. We banded two new species for the station in 2011: one Red-eyed Vireo …
Raptors Of Nebraska, Paul A. Johnsgard
Raptors Of Nebraska, Paul A. Johnsgard
Paul Johnsgard Collection
Nebraska is a regular host to 17 species of hawks, as well as two eagles and eight owls. Collectively, all these impressive-looking birds are known as “raptors,” which refers to their strong, sharply decurved and pointed beaks, their sharp, curved talons and their associated predatory abilities. Hawk and eagles are often called “diurnal raptors,” since they all hunt during daylight hours, whereas most of Nebraska’s owls hunt at night and are described as nocturnal raptors. But few biological statements lack exceptions, and some owls such as the burrowing owl are daytime-hunters, and some such as the great homed owl hunt …
Review Of Rare: Portraits Of America's Endangered Species. By Joel Sartore., Jim Mason
Review Of Rare: Portraits Of America's Endangered Species. By Joel Sartore., Jim Mason
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
Short of being in the presence of a creature, a really good photograph of one can also make a lasting impression. That is something RARE does compellingly, with exquisite portrait photos of 68 North American species that are dwindling dangerously in numbers or have recently recovered from the brink of extinction. Included are such Great Plains natives as the lesser prairie chicken, the interior least tern, and the black-footed ferret. All creatures were photographed with either a pure white or black background, but unconventional poses surprise the reader with each turn of the page, while creative framing and layout engage …
Review Of Sandhill And Whooping Cranes: Ancient Voices Over America's Wetlands. By Paul A. Johnsgard., Janice M. Hughes
Review Of Sandhill And Whooping Cranes: Ancient Voices Over America's Wetlands. By Paul A. Johnsgard., Janice M. Hughes
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
This charming, informative book has clearly been written by someone who truly understands and appreciates the magnificence of cranes. Indeed, Sandhill and Whooping Cranes: Ancient Voices over America's Wetlands is Paul Johnsgard's fourth book on the subject. The knowledge he imparts, presented from the heart, culminates almost five decades of personal observations and research on cranes. Moreover, the book features many attractive illustrations and detailed maps sketched by the author himself.
Sandhill and Whooping Cranes is a scholarly work with a much-welcomed personal touch. Whether its reader is contemplating a pilgrimage to observe these wonderful birds in the wild, or …
Summer Field Report, June–July 2011, W. Ross Silcock
Summer Field Report, June–July 2011, W. Ross Silcock
Nebraska Bird Review
The effects of major drought in the southwest United States on bird life in Nebraska has yet to be determined, as has the effect of the historic inundation of the Missouri River bottom lands from Gavins Point Dam to Rulo in eastern Nebraska. The water level at McConaughy is coincidentally at a maximum, ensuring that breeding habitat for Piping Plover and Least Tern was much reduced in the state overall. On the other hand, bottom lands wetlands above the flood level were expanded; Black-necked Stilts initiated a late nesting in Dakota Co in flooded fields that also attracted thousands of …

Nebraska Bird Review
The Bald Eagle (Halioeetus leucocephalus) was extirpated as a breeding species in Nebraska for most of the 20th Century. Nebraska's first active, successful, modern Bald Eagle nest was near Valley, Douglas County, in 1991 (Farrar 1991). Jorgensen et al. (2010) summarized modern Bald Eagle nesting records in Nebraska from 1950 to 2009. Jorgensen et al. (2010) noted the highest annual count of active nests was 54 in 2007. In this note we summarize the 2011 Bald Eagle nesting records in Nebraska.

Group Size And Nest Spacing Affect Buggy Creek Virus (Togaviridae: Alphavirus) Infection In Nestling House Sparrows, Valerie A. Brown, Charles R. Brown
Group Size And Nest Spacing Affect Buggy Creek Virus (Togaviridae: Alphavirus) Infection In Nestling House Sparrows, Valerie A. Brown, Charles R. Brown
Papers in Ornithology
The transmission of parasites and pathogens among vertebrates often depends on host population size, host species diversity, and the extent of crowding among potential hosts, but little is known about how these variables apply to most vector-borne pathogens such as the arboviruses (arthropod-borne viruses). Buggy Creek virus (BCRV; Togaviridae: Alphavirus) is an RNA arbovirus transmitted by the swallow bug (Oeciacus vicarius) to the cliff swallow (Petrochelidon pyrrhonota) and the introduced house sparrow (Passer domesticus) that has recently invaded swallow nesting colonies. The virus has little impact on cliff swallows, but house sparrows are seriously …
The Effects Of Social Context And Cache Survival On Pinyon Jay Caching Behavior, Christine L. Keefe
The Effects Of Social Context And Cache Survival On Pinyon Jay Caching Behavior, Christine L. Keefe
School of Biological Sciences: Dissertations, Theses, and Student Research
I examined how pinyon jays (Gymnorhinus cyanocephalus) assess and determine the risk of pilferage to their caches. Jays were allowed to cache in an open room while alone or while being observed by a conspecific. In a counterbalanced design, jays cached in the opposite treatment once they had finished recovering their caches. I compared birds’ behaviors between treatments in order to determine whether jays consider the presence of an observer in measuring the local competitive environment. Once all jays had completed alone- and observed- treatments, I ran the experiment once more to determine if individuals were consistent in …

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 …

Eurasian Wigeon In Sarpy County, Nebraska, Mark Brogie
Nebraska Bird Review
On Saturday 14 May 2011 on the Sarpy County Spring Count, Justin Rink, Jim Ducey, Ellen Brogie, and I found a Eurasian Wigeon at LaPlatte Bottoms. When first discovered the bird was in the company of multiple Gadwall and at least one adult male American Wigeon. The bird was a striking adult male bird with a rusty red head and a yellowish forehead. The breast was reddish and contrasted with the gray back and sides. This coloration made the white wing stripe more pronounced than that of the American Wigeon. The bird showed no evidence of hybridization. Multiple observers viewed …

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 …

Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen
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 (through 2013)
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 …

When asked to review this book I hadn't yet heard of it or its author, a wildlife photographer well known in his native Germany and the author of four photographic books published there, so I was eager to read it. The book is visually impressive, measuring 11" x 12", making it a true coffee-table production. Inside is a well-written 2S-page "primer" on whooping cranes by Krista Schlyer dealing with cranes in myth and legend, crane vocalizations and displays, and breeding biology. She also provides a brief survey of the whooping crane's population history, its near brush with extinction, and the …

As a raptor specialist, I eagerly look forward to the publication of state and regional books on birds of prey, typically rich with hard-to-find locally flavored information on distribution and biology. With the publication of Raptors of New Mexico, my home state has joined the ranks of the handful of states blessed with such volumes, and in fine form. This is an impressive work both in size and content, but the first thing anyone will notice are the photographs-hundreds, most top-notch, many capturing moods, scenes, and places unique to New Mexican raptors. In many ways the book is a showcase …
