Introduction
A common inhabitant of East Siberian larch forests, the Siberian or black-billed capercaillie (Tetrao urogalloides) ranges south to the limits of the boreal forests in the northern Mongolian mountains and east to the very coast of the Asian continent (KLAUS et al. 1989). Tetrao urogalloides MIDDENDORF (1851) has priority over T. parvirostris BONAPARTE (1856). Therefore, we prefer the T. urogalloides.
The subspecies T.u. stegmanni was first described on the basis of morphological differences by POTAPOV (1985) using specimens collected during Russian expeditions by KOZLOVA (1930). This description was based on 18 males in the collection at …

With the involvement of the World Bank, Zoological Society of London, Dutch Government and National University of Mongolia, the volumes of Mongolian Red Lists of Fish, Amphibians and Reptiles, Birds and Mammals were completed, and Mongolia is now among the few nations that have up-to-date conservation assessments for all vertebrates. Of the 476 assessed native bird species of Mongolia, 10% were categorized as regionally threatened including Near Threatened. A further 0.6% were categorized as Critically Endangered (CR), 1.7% as Endangered (EN), 3.3% as Vulnerable (VU), and 4.4% as Near Threatened (NT). Almost 90% of Mongolian birds are categorized as Least …
Nestling Food In The Desert Wheatear Oenanthe Deserti In The Dzungarian Gobi, Mongolia, 2012 Chur, Switzerland
Nestling Food In The Desert Wheatear Oenanthe Deserti In The Dzungarian Gobi, Mongolia, Ueli Rehsteiner
Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
The quality and size of nestling food of the Desert Wheatear Oenanthe deserti ssp. atrogularis were investigated in the spring of 2001 in the Dzungarian Gobi in Mongolia. Data are based on observations of nine pairs. Nestling food consisted of several taxa caught on the ground and in the air. Diptera, Coleoptera larvae, and Hymenoptera were the most frequent prey, that is, they contributed 17 to 30% of all food items each. The food composition changed with nestling age and season.
Food item size decreased with date. A higher proportion of multiple prey loadings were brought to nestlings in the …
Do Clark’S Nutcrackers Demonstrate What-Where-When Memory On A Cache-Recovery Task?, 2012 Luther College
Do Clark’S Nutcrackers Demonstrate What-Where-When Memory On A Cache-Recovery Task?, Kristy L. Gould, Amy J. Ort, Alan C. Kamil
Avian Cognition Papers
What-where-when (WWW) memory during cache recovery was investigated in six Clark’s nutcrackers. During caching, both red- and blue-colored pine seeds were cached by the birds in holes filled with sand. Either a short (3 day) retention interval (RI) or a long (9 day) RI was followed by a recovery session during which caches were replaced with either a single seed or wooden bead depending upon the color of the cache and length of the retention interval. Knowledge of what was in the cache (seed or bead), where it was located, and when the cache had been made (3 or 9 …

Ralph W. Schreiber Conservation Award, 2012, Paul A. Johnsgard
Paul Johnsgard Collection
The 2012 Ralph W. Schreiber Conservation Award is presented by the American Ornithological Union to Paul A. Johnsgard for his outstanding contributions to the conservation of the Great Plains of North America. Few living ornithologists have written as widely about birds, been more instrumental in promoting awareness of birds generally and the Great Plains avifauna specifically, or have influenced the public more than Paul A. Johnsgard.
The Great Plains of North America is one of the most imperiled landscapes in the world. The birds that depend upon these fragile habitats are being lost. Without the support of the public, policy-makers, …
Feather Biomechanics Of Penguins And Other Seabirds, 2012 California State University, San Bernardino
Feather Biomechanics Of Penguins And Other Seabirds, Katherine Elizabeth Johnson
Theses Digitization Project
Although many aspects of penguin biology have been studied, the feathers have received less attention except with regard to thermoregulation. The biomechanics of penguin feathers are the focus of this thesis. By studying penguins in comparison to other wing-propelled aquatic fliers, it may be possible to understand how penguin feathers evolved. Fourteen species were sampled, including aerial flyers, aerial flyers that are also wing propelled divers, as well as flightless wing propelled divers.
Brooding, Provisioning, And Compensatory Care In The Cooperatively Breeding Acorn Woodpecker, 2012 Old Dominion University
Brooding, Provisioning, And Compensatory Care In The Cooperatively Breeding Acorn Woodpecker, Walter D. Koenig, Eric L. Walters
Biological Sciences Faculty Publications
We analyzed reproductive investment in parental care (brooding and the provisioning of nestlings) in the acorn woodpecker (Melanerpes formicivorus), a cooperatively breeding species in which both polygynandry and helping-at-the-nest are common. As predicted based on the strategies pursued by birds of different sex and status, breeders generally invested more in parental care than helpers, and breeder females invested more than breeder males. Contrary to expectations, however, the degree to which individuals reduced their effort with increasing group size (i.e., patterns of load lightening or compensatory care) did not match overall investment. Instead, as group size increased, there was …
Patterns Of Seasonal Variation In Diet, Abundance, And Movement Of The Scarlet Macaw (Ara Macao) In Southern Belize, 2012 Antioch University - New England
Patterns Of Seasonal Variation In Diet, Abundance, And Movement Of The Scarlet Macaw (Ara Macao) In Southern Belize, Mark Stephen Mcreynolds
Antioch University Full-Text Dissertations & Theses
This study was conducted in 2008 and 2009 to determine if Scarlet Macaws (Ara macao), in subtropical southern Belize, Central America, are seasonal and elevational migrants and if their movement is influenced by seasonally abundant food. Reports from southern Belize indicated strongly seasonal sightings of macaws (N ≈ 200) in two separate areas of considerable difference in elevation. I monitored plant phenology plots (2 m x 500 m) in low (N = 6) and high (N = 6) elevation areas for a year to compare fruit abundance with macaw sightings in point counts on the plots and nearby. My point …
Heritable Choice Of Colony Size In Cliff Swallows: Does Experience Trump Genetics In Older Birds?, 2011 University of Tulsa
Heritable Choice Of Colony Size In Cliff Swallows: Does Experience Trump Genetics In Older Birds?, Erin A. Roche, Charles R. Brown, Mary Bomberger Brown
School of Natural Resources: Faculty Publications
The variation in breeding colony size seen in populations of most colonial birds may reflect heritable choices made by individuals that are phenotypically specialized for particular social environments. Although a few studies have reported evidence for genetically based choice of group sizes in birds, we know relatively little about the extent to which animals potentially rely on experience versus innate preferences in deciding how many conspecifics to settle with at different times of their lives. We conducted a cross-fostering experiment in 1997–1998 on cliff swallows, Petrochelidon pyrrhonota, in southwestern Nebraska, USA, in which some individuals were reared in colonies …
The Feathers Of Winter, 2011 University of Nebraska-Lincoln
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. …
Population Status, Habitat Dependence, And Reproductive Ecology Of Bahama Orioles: A Critically Endangered Synanthropic Species, 2011 Loma Linda University
Population Status, Habitat Dependence, And Reproductive Ecology Of Bahama Orioles: A Critically Endangered Synanthropic Species, Melissa R. Price, Valerie A. Lee, William K. Hayes
Faculty Works
Recent elevation of critically endangered Bahama Orioles (Icterus northropi) to species status prompted us to evaluate their population status, habitat use, and breeding ecology. From surveys, we estimated that at least 141 to 254 individuals remain globally, with 90 to 162, 24 to 44, and 27 to 48 individuals remaining on North Andros Island, Mangrove Cay, and South Andros Island, The Bahamas, respectively. Orioles were observed nesting exclusively in anthropogenic habitat (residential and agricultural land), but home ranges also included nearby pine forest and coppice (dry broadleaf forest). Most nests (40 of 46, or 87%) were in nonnative coconut palm …

First Discovery Of A Four-Egg Clutch For Mountain Plover (Charadrius Montanus) In Nebraska, 2011 Nebraska Prairie Partners
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 …

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 …

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 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 …
