The History And Significance Of Taxidermy Bird Collections In North America: Bgsu's Own Undervalued Collection And Its Future, Kristin Burnside

Honors Projects

Taxidermy, despite its association with the bizarre and outlandish, has a rich history and culture that helped to define post-Civil War America and its pursuit of knowledge and reconnection with nature. With the widespread publication and availability of how-to guides, natural history collecting and taxidermy became accessible to any individual regardless of age, gender, or class. The hobby required physicality and courage to collect unique and interesting specimens, and intellect and creativity to conserve and display them, all of which inherently connected the avocation with respect. With varying levels of success, hobbyists experimented with different chemicals, such as arsenic, in …

Temporal And Spatial Blood Feeding Patterns Of Urban Mosquitoes In The San Juan Metropolitan Area, Puerto Rico, Matthew W. Hopken, Limarie J. Reyes-Torres, Nicole Scavo, Antoinette J. Piaggio, Zaid Abdo, Daniel Taylor, James Pierce, Donald A. Yee

USDA Wildlife Services: Staff Publications

Simple Summary: Understanding the biodiversity of urban ecosystems is critical for management of invasive and pest species, conserving native species, and disease control. Mosquitoes (Culicidae) are ubiquitous and abundant in urban ecosystems, and rely on blood meals taken from vertebrates. We used DNA from freshly blood-fed mosquitoes to characterize the diversity of vertebrate host species in the San Juan Metropolitan Area, Puerto Rico. We collected two mosquito species that fed on a variety of vertebrates. Culex quinquefasciatus fed on 17 avian taxa (81.2% of blood meals), seven mammalian taxa (17.9%), and one reptilian taxon (0.85%). Aedes aegypti blood meals were …

Functional Morphology Of Gliding Flight I. Modeling Reveals Distinct Performance Landscapes Based On Soaring Strategies, Lindsay D. Waldrop, Yanyan He, Tyson L. Hedrick, Jonathan Rader

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The physics of flight influences the morphology of bird wings through natural selection on flight performance. The connection between wing morphology and performance is unclear due to the complex relationships between various parameters of flight. In order to better understand this connection, we present a holistic analysis of gliding flight that preserves complex relationships between parameters. We use a computational model of gliding flight, along with analysis by uncertainty quantification, to 1) create performance landscapes of gliding based on output metrics (maximum lift-to-drag ratio, minimum gliding angle, minimum sinking speed, lift coefficient at minimum sinking speed); and 2) predict what …

Noise, Avian Abundance, And Productivity At Banding Stations Across The Continental United States, Amber M.B. Ng, Michael L. Pontius, Stacy L. Deruiter, Darren S. Proppe

University Faculty Publications and Creative Works

Noise is an increasingly common component of the natural world, due in large part to human activity. Anthropogenic noise negatively impacts abundance, health, and reproduction in many songbird populations. A few studies have reported altered abundance at larger scales. But whether continental trends are being detected at banding stations, which also offer data on productivity and survivorship, is unknown. Further, it is not known whether localized trends correlate with population trends observed at larger scales. We used breeding season data from 1160 constant-effort banding stations (Monitoring Avian Productivity and Survivorship; MAPS) and a spatially explicit noise model to determine whether …

Wildlife Diversity And Relative Abundance Among A Variety Of Adjacent Protected Areas In The Northern Talamanca Mountains Of Costa Rica, Carolina Sáenz-Bolaños, Todd K. Fuller, Eduardo Carillo J.

Environmental Conservation Faculty Publication Series

Protected areas are intended to achieve the long-term conservation of nature, but not all such areas are equal in their effectiveness because of their varying regulation of human activities. In Costa Rica, we assessed mammal and bird species presence and relative abundance in three protected areas in the northern Talamanca Mountains. In this humid tropical forest area, we placed camera traps in an adjacent national park, forest reserve, and indigenous territories, each with a different mix of human activities. In 10,120 trap nights, we obtained 6181 independent photos of mostly mammals (34 species other than humans) and birds (34 species). …

Nesting Success Of Dickcissel (Spiza Americana) And Non-Breeding Grassland Bird Use Of Northwest Arkansas’ Remnant And Restored Tallgrass Prairies, Alyssa L. Derubeis

Graduate Theses and Dissertations

Dwindling populations of North American grassland birds are linked to habitat loss. Tallgrass prairie only covers 3% of its pre-settlement-era range. Small-scale restoration projects attempt to increase acreage for prairie avifauna, and while some breeding grassland species are present at these sites, nesting success and non-breeding use are still largely unknown. Both life history aspects are required for effective grassland bird conservation. My first objective was to access nest success of the Dickcissel (Spiza americana) at two remnant and two restored tallgrass prairies in Northwest Arkansas. From May-August 2017 and 2018, I found 114 nests that I monitored to determine …

The Traits That Predict The Magnitude And Spatial Scale Of Forest Bird Responses To Urbanization Intensity, Grant D. Paton, Alexandra V. Shoffner, Andrew M. Wilson, Sara A. Gagné

Environmental Studies Faculty Publications

As humans continue moving to urban areas, there is a growing need to understand the effects of urban intensification on native wildlife populations. Forest species in remnant habitat are particularly vulnerable to urban intensification, but the mechanisms behind these effects are poorly understood. An understanding of how species traits, as proxies for mechanisms, mediate the effects of urban intensification on forest species can help fill this knowledge gap. Using a large point count dataset from the Second Pennsylvania Breeding Bird Atlas, we tested for the effects of species traits on the magnitude and spatial scale of the responses of 58 …

Cause‐Specific Mortality Of The World’S Terrestrial Vertebrates, Jacob E. Hill, Travis L. Devault, Jerrold L. Belant

USDA Wildlife Services: Staff Publications

Aim: Vertebrates are declining worldwide, yet a comprehensive examination of the sources of mortality is lacking. We conducted a global synthesis of terrestrial vertebrate cause‐specific mortality to compare the sources of mortality across taxa and determine predictors of susceptibility to these sources of mortality.

Location: Worldwide.

Time period: 1970–2018.

Major taxa studied: Mammals, birds, reptiles and amphibians.

Methods: We searched for studies that used telemetry to determine the cause of death of terrestrial vertebrates. We determined whether each mortality was caused by anthropogenic or natural sources and further classified mortalities within these two categories (e.g. harvest, vehicle collision and predation). …

The Relative Effects Of Forest Amount, Forest Configuration, And Urban Matrix Quality On Forest Breeding Birds, Alexandra V. Shoffner, Andrew M. Wilson, Wenwu Tang, Sara A. Gagné

Environmental Studies Faculty Publications

Urbanization modifies landscape structure in three major ways that impact avian diversity in remnant habitat: habitat amount is reduced and habitat configuration and matrix quality are altered. The relative effects of these three components of landscape structure are relatively well-studied in agricultural landscapes, but little is known about the relative effect of urban matrix quality. We addressed this gap by investigating the relative effects of forest amount, forest configuration, and matrix quality, indicated by degree of urbanization and agriculture amount, on the diversity of three guilds of forest birds using data from 13,763 point counts from Pennsylvania, USA. Forest amount …

Examining Patterns In Nest Predation Using Artificial Nests, Victoria L. Simonsen

School of Natural Resources: Dissertations, Theses, and Student Research

The use of artificial nests to study the predation of avian nests has faced disregard by ecologists due to inconsistencies found between the survival rates of real and artificial nests across studies and reviews. The negative perception of artificial nests providing an inconsistent assessment of survival has thus fostered the perception that artificial nests are a secondary option to be used to overcome logistical hurdles associated with achieving sufficient sample sizes in systems where study species are rare or elusive, or as merely a preliminary method to study predation across gradients. We argue that the greatest mistake ecologists have made …

An Integrated Evaluation Of The Conservation Reserve Enhancement Program In South Dakota, Jarrett D. Pfrimmer

Electronic Theses and Dissertations

Grassland restoration efforts in North America typically share the goal of improving ecological conditions for wildlife; however, it is unclear in many cases if goals are met. The South Dakota Conservation Reserve Enhancement Program (CREP) was initiated to alleviate agriculturally-related environmental degradation by converting 40,469 hectares of eligible cropland and marginal pastureland to perennial vegetation. The program aims to provide habitat for obligate grassland breeding songbirds, while producing an additional 285,000 pheasants and 60,000 ducks annually. As part of a collaborative comprehensive evaluation effort, my research assessed the response of grassland-dependent breeding birds to CREP implementation at varying spatial scales …

United States Geological Survey: Staff Publications

1.Immunological reagents for wild, non-model species are limited or often non-existent for many species.

2. In this study, we compare the reactivity of a newanti-passerine IgY secondary antibody with existing secondary antibodies developed for use with birds. Samples from 41 species from the following six avian orders were analysed: Anseriformes (1 family, 1 species), Columbiformes (1 family, 2 species), Galliformes (1 family, 1 species), Passeriformes (16 families, 34 species), Piciformes (1 family, 2 species) and Suliformes (1 family, 1 species). Direct ELISAs were performed to detect total IgY using goat anti-passerine IgY, goat anti-chicken IgY or goat anti-bird IgY secondary …

Assessing Mammal And Bird Biodiversity And Habitat Occupancy Of Tiger Prey In The Hukaung Valley Of Northern Myanmar, Hla Naing

Masters Theses

I used results from camera traps set for tigers (Panthera tigris) during 2001-2011 in the Hukaung Valley Wildlife Sanctuary of northern Myanmar to assess overall biodiversity of large mammal and bird species, and to identify differences in photo rates inside and outside of the most protected core area of the Sanctuary. A total of 403 camera stations were deployed during October-July in the dry seasons of 2001-2011, 260 inside the Core area and 143 Outside. From 10,750 trap-nights I obtained 2,077 independent photos of wildlife species and 699 of domestic animals and humans, including 35 species of wild …

Effects Of Forest Fragmentation On Central Amazonian Bird Demography, Jared Desmond Wolfe

LSU Doctoral Dissertations

Avian diversity in degraded fragmented Amazonian landscapes depends on the persistence of species in cleared and disturbed areas. Regenerating forest facilitates bird dispersal within degraded Amazonian landscapes and may tip the balance in favor of persistence in previously depauperate habitat patches. Despite the potential value of Amazonian second growth, we lack comparisons of demography among second growth, continuous forest, forest fragments in regenerating landscapes, and truly isolated fragments. Here, we used point-count and capture data to compare Amazonian bird communities among continuous forest plots, 100 ha forest fragments with adjacent second growth, 100 ha forested islands bounded by water, young …

Avian Communities And Landscape Characteristics Of Golf Courses Within The Beaufort County Sea Island Complex, Jessica Gorzo

All Theses

The native breeding bird community of Beaufort County, South Carolina is experiencing landscape alteration in several forms. A prevalent human land use in the coastal zone is golf course development. This study explored the relationship between golf course land cover (n=23) and avian community metrics. Each study site consisted of the in-play area of the golf course, surrounded by a 400 m zone. Landscape metrics were calculated for each study site, and served as independent variables. The dependent variables were the following avian community metrics: species richness, neotropical migrant richness, abundance, diversity, evenness, and mean Partners in Flight (PIF) score. …

Behavioural Adaptation Of A Bird From Transient Wetland Specialist To An Urban Resident, John Martin, Kristine O. French, Richard Major

Faculty of Science - Papers (Archive)

Dramatic population increases of the native white ibis in urban areas have resulted in their classification as a nuisance species. In response to community and industry complaints, land managers have attempted to deter the growing population by destroying ibis nests and eggs over the last twenty years. However, our understanding of ibis ecology is poor and a question of particular importance for management is whether ibis show sufficient site fidelity to justify site-level management of nuisance populations. Ibis in non-urban areas have been observed to be highly transient and capable of moving hundreds of kilometres. In urban areas the population …

Ecological Profiling Of Bird-Mosquito Interactions In Central Virginia, Anna Riggan

Theses and Dissertations

Current methods of mosquito surveillance estimate general population abundances, but fail to represent the relationship of vector abundance to host density important to determining transmission risk of mosquito-borne pathogens (MBP). We sought to address this limitation by creating a novel mosquito trap that directly sampled mosquitoes seeking to feed on nesting birds. The primary objectives of this study were to (1) assess the efficiency of the Nest Mosquito Trap (NMT) and how this is affected by nest box size. (2) assess whether the NMT affects bird, specifically nest success in Prothonotary Warblers (Protonotaria citrea), and adult behavior. (3) compare our …

High Speed Flight At Low Altitude: Hazard To Commercial Aviation ?, Paul F. Eschenfelder , Capt.

Paul F. Eschenfelder

Commercial aircraft are capable of, and in fact, do, operate at high speed (>250 knots indicated airspeed [KIAS]) at low altitude (below 10,000’ above ground level) worldwide. Design, construction and certification standards for these aircraft were developed over 40 years ago. Since the development of these standards populations of large flocking birds have increased dramatically in many parts of the world. Yet neither design/construction standards nor operational practice have changed to reflect the new threat. Subsequent serious damage resulting from recent collisions indicates change is necessary. Since 2003, flight rules in Canada and the United States have been amended, …

A Review And Synthesis Of Bird And Rodent Damage Estimates To Select California Crops, Karen Gebhardt, Aaron M. Anderson, Katy N. Kirkpatrick, Stephanie A. Shwiff

USDA Wildlife Services: Staff Publications

A comprehensive literature review was conducted to identify the magnitude of bird and rodent damage to 19 economically important crops in California. Interviews with agriculture experts provided additional information about damages. Monte Carlo simulations were used to derive summary estimates of damages to each crop. A meta-analysis indicated that summary damage estimates from expert interviews were higher than estimates from field studies and surveys. It was also found that there has been a downward trend over time in damages to almonds and grapes. The results of our study indicate that damages from bird and rodents remain high for many crops …

Clinical And Pathologic Responses Of American Crows (Corvus Brachyrhynchos) And Fish Crows (C Ossifragus) To Experimental West Nile Virus Infection, N. M. Nemeth, B. V. Thomsen, T. R. Spraker, J. M. Benson, A. M. Bosco-Lauth, P. T. Oesterle, J. M. Bright, J. P. Muth, T. W. Campbell, T. L. Gidlewski, R. A. Bowen

USDA Wildlife Services: Staff Publications

West Nile virus (WNV)-associated disease has a range of clinical manifestations among avian taxa, the reasons for which are not known. Species susceptibility varies within the avian family Corvidae, with estimated mortality rates ranging from 50 to 100%. We examined and compared virologic, immunologic, pathologic, and clinical responses in 2 corvid species, the American crow (Corvus brachyrhynchos) and the fish crow (C ossifragus), following experimental WNV inoculation. Unlike fish crows, which remained clinically normal throughout the study, American crows succumbed to WNV infection subsequent to dehydration, electrolyte and pH imbalances, and delayed or depressed humoral immune …

Impacts On A Threatened Bird Population Of Removals For Translocation, David Bain, Kristine French

Faculty of Science - Papers (Archive)

The removal of individuals from a population may occur for several reasons and responses of populations will vary depending on the magnitude and nature of the removal and the life history of the species. An understanding of the effects of loss of individuals on these populations, and the mechanism of replacement, will be important to conservation. This maybe particularly important where wild individuals are used for the increasingly popular conservation strategy of translocation. During the recent translocation of the endangered eastern bristlebird (Dasyornis brachypterus), two monitoring sites were established in the wild source population, one where removals were to take …

An Overview Of Avian Radar Developments – Past, Present And Future, Tim J. Nohara, B. Eng, M. Eng, Peter Weber, Andrew Ukrainec, Al Premji, Graeme Jones

2007 Bird Strike Committee USA/Canada, 9th Annual Meeting, Kingston, Ontario

The objective of this paper is to stand back and take an organized look at these developments in avian radar technology, with a view towards improving our understanding of this complex tool set. By reviewing the past, a context will be provided within which one can better appreciate what has been accomplished in the present, and where technology and products still need to go in the future. It is hoped that a better understanding will assist stakeholders in making the best use of these tools, today and tomorrow.

Height Distribution Of Birds Recorded By Collisions With Civil Aircraft, Richard A. Dolbeer

USDA Wildlife Services: Staff Publications

The National Wildlife Strike Database for Civil Aviation in the United States contained 38,961 reports of aircraft collisions with birds (bird strikes) from 1990–2004 in which the report indicated the height above ground level (AGL). I analyzed these strike reports to determine the distribution of all strikes and those strikes causing substantial damage to aircraft by height. For the 26% of strikes above 500 feet (152 m) AGL (n=10,143), a simple negative exponential model, with height as the independent variable, explained 99% of the variation in number of bird strikes per 1,000-foot (305-m) interval. Strikes declined consistently by 32% every …

Percentage Of Wildlife Strikes Reported And Species Identified Under A Voluntary Reporting System, Sandra E. Wright, Richard A. Dolbeer

2005 Bird Strike Committee-USA/Canada 7th Annual Meeting, Vancouver, BC

Reporting of wildlife strikes with civil aircraft in the USA is voluntary but strongly encouraged by the Federal Aviation Administration (FAA) through Advisory Circulars and FAA publications. The National Wildlife Strike Database contained 59,196 strike reports for civil aircraft, 1990-2004. An initial analysis of independent strike data from an eastern USA airport in 1994 indicated that less than 20% of strikes were actually reported to the FAA for inclusion in the National Wildlife Strike Database. To obtain an improved estimate of the percent of strikes reported, we obtained 14 sets of wildlife strike data maintained by three airlines and three …

Affordable, Real-Time, 3-D Avian Radar Networks For Centralized North American Bird Advisory Systems, Peter Weber, Tim J. Nohara, Sidney A. Gauthreaux Jr.

2005 Bird Strike Committee-USA/Canada 7th Annual Meeting, Vancouver, BC

Affordable avian radar systems are being developed for Natural Resource Management (NRM) and bird aircraft strike hazard (BASH) applications. Recently [I], the authors have reported on mobile avian radar system requirements and on a system design that is state-of-the-art. In the present paper, the system design of a single avian radar is expanded in scope to address 3-D avian radar networks. These are essential to fully realize an affordable yet high-performance North American bird advisory system. The proposed avian radar network design includes antenna, transceiver and signal processor designs for the avian radar sensor, network design, sensor integration, and system …

Impacts Of Small Mammals And Birds On Low-Tillage, Dryland Crops, Ray T. Sterner, Brett E. Petersen, Stanley E. Gaddis, Kenneth L. Tope, David J. Poss

USDA Wildlife Services: Staff Publications

During 2000–2001, small mammals, birds, and potential corn/soybean damage were studied at a low-tillage, non-irrigated agricultural research site in the Colorado Piedmont. A small mammal surveyinvolved four trapping sessions and 18, 12-live-trap grids each. Within years, two grids each were placed at random, fixed locations in experimental corn, fallow, millet, pea, soybean, sunflower, and wheat plots at the site; two off-plot grids each were set at random, fixed locations <100m from the north and south edge of these plots. In 2001, periodic bird observations were conducted, and damage to corn and soybean plants was assessed. Capture rates were low during all trap sessions (range 0.1%–3.3%, Χ̅ = 2:2%). Sixty-three small mammals were captured and 39 were recaptured. Captures included deer mouse (Peromyscus maniculatus), northern grasshopper mouse (Onychomys leucogaster), thirteen-lined ground squirrel (Spermophilus tridecemlineatus), and western harvest mouse (Reithrodontomys megalotis). Deer mice accounted for 56 of …

Wildlife-Caused Losses Of Agricultural Commodities In 1994 With Emphasis On The Great Plains, A.P. Wywialowski

Great Plains Wildlife Damage Control Workshop Proceedings

The USDA, National Agricultural Statistics Service (NASS) surveyed 16,000 agricultural producers in January 1995. Of 10,144 respondents nationwide, 58% reported wildlife-caused losses of their commodities, an increase from 55% in 1989. Based on the median value of all producers' estimates of their losses, wildlife-caused losses cost producers approximately $591 million in 1994, $130 million more than in 1989. Losses presented are based on median producer estimates which have been shown to be consistent with field-measured estimates of damage. Because the dollar value of losses are based on median estimates, extremes of reported losses do not affect these results. If all …

Avian Repellents: Options, Modes Of Action, And Economic Considerations, J. Russell Mason, Larry Clark

National Wildlife Research Center Repellents Conference 1995

The present manuscript considers visual, auditory, tactile, chemosensory, and physiologic repellents currently available for use in the United States. Discussion of tactile, chemosensory, and physiologic repellents is emphasized for three reasons. First, these products are preferred by users. Second, application of these substances is regulated by state and federal agencies. Third, only four active ingredients are legally available at the present time. This lack reflects difficulties in obtaining regulatory approval and limited market size.
