Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Landscapes in agricultural systems continue to undergo significant change, and the loss of biodiversity is an ever-increasing threat. Although habitat restoration is beneficial, management actions do not always result in the desired outcome. Managers must understand why management actions fail; yet, past studies have focused on assessing habitat attributes at a single spatial scale, and often fail to consider the importance of ecological mechanisms that act across spatial scales. We located survey sites across southern Nebraska, USA and conducted point counts to estimate Ring-necked Pheasant abundance, an economically important species to the region, while simultaneously quantifying landscape effects using a …

The History And Reintroduction Of Whooping Cranes At White Lake Wetlands Conservation Area, Louisiana, Gay M. Gomez
Proceedings of the North American Crane Workshop
On 16 February 2011, whooping cranes (Grus americana) were reintroduced in the wetlands of southwest Louisiana, after an absence of 61 years. This brief communication provides background on the historical presence of whooping cranes in this region, describes the long road to reintroduction, presents observations from the reintroduction’s first day, and offers thoughts on its future prospects.
On 15 May 1939, biologist John J. Lynch of the U.S. Fish and Wildlife Service observed 13 whooping cranes in the remote freshwater marsh north of White Lake in Vermilion Parish, Louisiana. He not only confirmed what local residents and trappers had long …

Air Sac Nematode Monopetalonema Alcedinis In A Belted Kingfisher (Megaceryle Alcyon) In Maryland, Usa, Ellen Bronson, Kathleen Kelly, Eric P. Hoberg
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Sporadic and geographically widespread reports of parasites affecting the Belted Kingfisher (Megaceryle alcyon) have been published but few have described details of the pathology. A female, adult kingfisher was found dead in a heavily wooded area of a zoo in Maryland, USA. At necropsy, numerous sexually dimorphic, 4.4–40.5-cm adult Monopetalonema alcedinis nematodes were found tightly wound within the coelomic cavity between organs and completely filling the caudal thoracic and abdominal air sacs. Abundant, 30–60-mm diameter, larvated, thick-walled ova were found in the bronchi and parabronchi, within the mesentery, and in the serosa of multiple coelomic organs. Monopetalonema alcedinis …

Insights From Project Feederwatch: Changes In The Abundance And Occurrence Of Birds In New Hampshire Over The Past 24 Years, Lee A. Sutcliffe
Honors Theses and Capstones
Changes in the climate and land use over time can lead to changes in the composition of wildlife communities. Using data from Project FeederWatch, we examine trends in the abundance and occurrence of birds documented in the winters from 1988 to 2012 in New Hampshire. Changes in abundance and occurrence are summarized for individual bird species as well as across species based on life history traits. In addition, we examined trends for the state as a whole as well as in subregions. We discuss these changes with regards to the variations of climate and land use that are occurring throughout …

More than 100 species of migratory birds pass through New York City during spring and fall migrations. Located at the nexus of several migratory routes, New York City’s tall buildings and reflective glass pose a serious threat to over 100 species of migratory birds. Since 1997, NYC Audubon has led Project Safe Flight (PSF), a volunteer-based citizen-science project, with the goal of monitoring and mitigating bird collisions. We examined 16 years of PSF data, during which volunteers collected over 6,000 birds of 126 different species. The top two species, White-throated Sparrow and Common Yellowthroat, make up 23% of all collisions. …

Birds And Birding In Wyoming’S Bighorn Mountains Region, Jacqueline L. Canterbury, Paul A, Johnsgard, Helen F. Downing
Zea E-Books Collection
The Bighorn Mountains consist of a relatively well-isolated north-south mountain range in north-central Wyoming that had their origins during the early Cenozoic era, 50-65 million years ago. The present-day Bighorn range is more than 100 miles in length and has a maximum elevation of 13,167 feet (Cloud Peak), only slightly less than the highest peak in Wyoming (Gannett Peak, at 13,804 feet). The mountains are flanked to the west by the Bighorn River basin, and to the east by the Powder River basin, both of which support only semi-desert vegetation dominated by sagebrush. Elevations of the Powder River basin near …

The Influence Of Different Cover Types On American Robin Nest Success In Organic Agroecosystems, John E. Quinn, Amy Oden, James R. Brandle
Biology Publications
There are many opportunities for biodiversity conservation in organic farm systems. Successful and sustainable conservation efforts in organic systems, however, need to measure appropriate outcomes. In particular, data are needed on the breeding success of associated wildlife species. We measured nesting success of the American Robin (Turdus migratorius) in woodlands embedded within eight organic farms in eastern Nebraska. We modeled daily nest survival rate to identify land use and land cover patterns that optimize conservation of birds in organic farm systems. The percentage of a crop in the fields adjacent to linear woodlands best predicted daily survival rate. …

Birds In Residential Metropolitan New Orleans Neighborhoods And Their Relationships To The Batture And Yard Vegetation, Ruth A. Guymon
Birds In Residential Metropolitan New Orleans Neighborhoods And Their Relationships To The Batture And Yard Vegetation, Ruth A. Guymon
LSU New Orleans Theses and Dissertations
Metropolitan New Orleans Neighborhoods were surveyed in order to determine how bird populations responded to distance from the batture, percent canopy cover, stem counts, and understory vegetation. Surveys were conducted in the spring and summer of 2010. It was found that batture birds, urban birds, and pooled birds all had greater species richness and abundance in the spring in areas with more canopy cover, higher stem counts, more understory vegetation, and distances closer to the batture. In the summer, batture birds had greater richness and abundance in areas with more canopy cover, higher stem counts, and more understory cover. This …

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

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 …

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 …
