Potential For Barn Owl As Rodent Biological Control In Central California Vineyards, Hannah Tillmann

Biological Sciences

The pocket gopher (Thomomys bottae) and voles (Microtus spp.) cause significant economic damage to vineyards. In response, many growers have taken steps to attract Barn Owls (Tyto alba) to their properties to help keep these rodent populations in check. This research project investigated Barn Owl consumption of pocket gophers and voles in Central California vineyards in order to assess the efficiency of this integrated pest management strategy. I collected a total of 715 owl pellets from five vineyard locations in Templeton and Paso Robles, California over an eight-month period during nesting and post-fledging seasons. I …

2011–2012 Christmas Bird Counts

Nebraska Bird Review

Fifteen counts, one more than last year, were held during the period, and a total of 139 species, 10 fewer than last year, were found. This was a count season of record totals for the state for a number of species. Factors contributing to this include the number of counts, the number of participants and the weather. More counts (15) were run than in any previous year, and several counts (Lake McConaughy in particular) had a much greater than average number of participants. The weather prior to the count period was mild, and most of the circles had unusually warm …

Report Of A Nesting Sora (Porzana Carolina), William M. Lemburg, Wayne J. Mollhoff

Nebraska Bird Review

During the summer of 2008, long-time NOU member and former NOU Treasurer William (Bill) Lemburg of Cairo, Howard Co., Nebraska, discovered the nest of a Sora (Porzana carolina). On 29 July 2008, while using a small flat-bottomed boat to gather duckweed (Spirodela polyrhiza) on a small pond near his bird pens to feed the exotic waterfowl he raises, he noted a pair of Sora walking about, foraging atop the dense growth of duckweed. The pair ignored his presence even though, as he later discovered, he was within 10 feet of their nest. The following evening, 30 …

Winter Field Report, December 2011 To February 2012, W. Ross Silcock

Nebraska Bird Review

The most obvious feature of this winter’s avian movements was the number of Snowy Owls, unprecedented in living memory, that invaded the state. A tally maintained by Joel Jorgensen and Lauren Dinan of Nebraska Game and Parks indicated that over 200 snowies were found in the state, and most were documented. Not as popular with the public, but perhaps of greater scientific interest were the mid-winter reports of species normally rare at this time of year. Most notable in this respect were waterfowl, grebes, cranes, and sparrows. A read-through of these species suggests the very mild winter experienced over most …

Prairie Dog Lesson, Paul A. Johnsgard

Paul Johnsgard Collection

It seems to me, in view of all the concerted efforts of our state's elective officers to enact a set of morals for every Nebraskan to live by - especially relative to marriage and reproduction - they could take a lesson from prairie dogs, rather than passing a law requiring the poisoning of entire colonies at the whim of an unhappy neighbor. ...

The Lower Platte River and its major tributaries provide important nesting habitat for two state and federally protected bird species, the Interior Least Tern (Sternula antillarum athalassos) and Piping Plover (Charadrius melodus). The Tern and Plover Conservation Partnership (TPCP), based at the University of Nebraska-School of Natural Resources, and the Nongame Bird …

Mid-Contract Management Of Conservation Reserve Program Grasslands Provides Benefits For Ring-Necked Pheasant Nest And Brood Survival, Ty W. Matthews, J. Scott Taylor, Larkin A. Powell

School of Natural Resources: Faculty Publications

Conservation Reserve Program (CRP) fields may provide good habitat for nesting and brood-rearing ring-necked pheasants (Phasianus colchicus) during early stages of succession. But, the success of hens in early successional CRP, relative to late successional CRP and other grassland habitats, has yet to be evaluated. The reproductive period is especially critical for populations of pheasants, and CRP’s benefits to hens and chicks may decrease as fields age because of loss of vegetative diversity, decrease in vegetation density, and accumulation of residual litter. During 2005– 2006, we evaluated spatial and temporal variation in nest and brood survival for radio-marked hen pheasants …

Patterns Of Incubation Behavior In Northern Bobwhites (Colinus Virginianus), Jonathan S. Burnam, Gretchen Turner, Susan Ellis-Felege, William E. Palmer, D. Clay Sisson, John P. Carroll

School of Natural Resources: Faculty Publications

Patterns of incubation and nesting behavior for many species of birds, especially those with cryptic nests, have been difficult to obtain due to logistical and technological limitations. As a result, little is known about the daily attendance rhythms and behavioral patterns of many species, including the Northern Bobwhite (Colinus virginianus), despite this species being one of the most studied birds in the world. Incubation represents parental investment in offspring, and a multitude of factors may affect investment behaviors, including reproductive ecology, sex and age of parent, habitat quality, clutch age, and timing in the nesting season. Most Northern Bobwhite nests …

Male Savannah Sparrows Provide Less Parental Care With Increasing Paternity Loss, Noah G. Perlut, Lindsay M. Kelly, Nathan J. Zalik, Allan M. Strong

Environmental Studies Faculty Publications

Male parental care can significantly affect fledging success and, therefore, is a strong target of both natural and sexual selection. However, for songbird species that exhibit extra-pair paternity, males may reduce parental care based on how much paternity they have lost in a brood. We studied Passerculus sandwichensis (Savannah Sparrow) male parental care relative to the proportion of extra-pair young in the nest, to see if males adjusted care in response to increasing loss of paternity. Males brought less food (mass) with increasing rates of extra-pair paternity, although male provisioning did not influence fledging success. These results contrast with a …

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.

Bird Red List And Its Future Development In Mongolia, Sundev Gombobaatar, D. Samiya, Jonathan M. Baillie

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

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, 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 …

Ecology And Behaviour Of The Black-Billed Capercaillie (Tetrao Urogalloides Stegmanni) In The Khentej Mountains, Mongolia, Siegfried Klaus, Karl-Heniz Schindlatz, Alexander V. Andreev, Hans-Heiner Bergmann

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

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 …

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, …

Patterns Of Seasonal Variation In Diet, Abundance, And Movement Of The Scarlet Macaw (Ara Macao) In Southern Belize, Mark Stephen Mcreynolds

Antioch University 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 …

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 …

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 …

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 …

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 …

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. …
