The North American Quails, Partridges, And Pheasants, 2017 University of Nebraska-Lincoln
The North American Quails, Partridges, And Pheasants, Paul A. Johnsgard
This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel’s, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are ...

Rethinking Urban Green Infrastructure As A Means To Promote Avian Conservation, 2017 The University of San Francisco
Rethinking Urban Green Infrastructure As A Means To Promote Avian Conservation, Allen Lau
Master's Projects and Capstones
There is an under-recognized potential for cities to use urban green infrastructure to contribute to avian biodiversity conservation. At the global scale, climate change and growing urbanization are primary global drivers leading to decline and homogenization in world bird populations. Birds are fundamental and intricate species in ecosystems, and even in urban areas, act as indicator and regulator species contributing to healthy ecosystem function. While many cities have recognized the economic and social benefits associated with green spaces, such as the vast benefits ecosystem services provide to the urban dweller, the use of green spaces to concurrently contribute to avian ...

Winter Diet Of Bobolink, A Long-Distance Migratory Grassland Bird, Inferred From Feather Isotopes, 2017 Vermont Center for Ecostudies
Winter Diet Of Bobolink, A Long-Distance Migratory Grassland Bird, Inferred From Feather Isotopes, Rosalind B. Renfrew, Jason M. Hill, Daniel H. Kim, Christopher Romanek, Noah G. Perlut
Biology Faculty Publications and Presentations
Effective conservation of migratory bird populations depends on advancements in our understanding of processes throughout the life cycle. Fundamental information about wintering ecology (e.g., habitat use and diet composition) remains limited, which limits assessment of threats to populations during winter. Bobolink (Dolichonyx oryzivorus) is a year-round grassland obligate and Nearctic-Neotropical migrant that undergoes 2 complete molts each year, including a complete prealternate molt on the South American wintering grounds. This unusual winter molt provides a rare opportunity to examine, using stable isotope analysis, the timing and contribution of foraging resources in the Bobolink diet prior to northbound migration from ...
Spatial Models To Account For Variation In Observer Effort In Bird Atlases, 2017 Gettysburg College
Spatial Models To Account For Variation In Observer Effort In Bird Atlases, Andrew M. Wilson, Daniel W. Brauning, Caitlin Carey, Robert S. Mulvihill
Environmental Studies Faculty Publications
To assess the importance of variation in observer effort between and within bird atlas projects and demonstrate the use of relatively simple conditional autoregressive (CAR) models for analyzing grid-based atlas data with varying effort. Pennsylvania and West Virginia, United States of America. We used varying proportions of randomly selected training data to assess whether variations in observer effort can be accounted for using CAR models and whether such models would still be useful for atlases with incomplete data. We then evaluated whether the application of these models influenced our assessment of distribution change between two atlas projects separated by twenty ...
Mountain Plover Nest In Kimball County, 2017 Midcontinent Ecological Science Center
Mountain Plover Nest In Kimball County, Stephen J. Dinsmore
Stephen J Dinsmore
On 18 May 1995 I observed two adult Mountain Plovers 5 mi west and 1.25 mi north of Bushnell in southwest Kimball county. The birds were in an area of short-grass prairie interspersed with clumps of prickly pear and bare ground. I observed both birds almost continuously from 1-2 p.m. MDT. The first bird was along the road south of the fenceline, just after the road climbs on top of the plateau. The second bird was about 0.1 mi to the north on the west side of the road. Both birds were medium-sized, plain shorebirds, similar in ...
Long-Tailed Jaegers In Western Nebraska, 2017 Selected Works
Long-Tailed Jaegers In Western Nebraska, Stephen J. Dinsmore
Stephen J Dinsmore
The Long-tailed Jaeger is an accidental migrant in Nebraska with just one accepted record through the mid-1990s. Based on records from adjacent states, especially Colorado (Andrews and Righter 1992) and Wyoming (Faulkner 2010), the species is probably more frequent than these records indicate, and its status is further complicated by possible confusion with Pomarine and Parasitic jaegers. In this article I report details of four records of Long-tailed Jaegers in western Nebraska and comment on the species' identification and status in the state.
Notes On Bird Sightings In Nebraska March 1997, 2017 Nebraska Ornithologists' Union
Notes On Bird Sightings In Nebraska March 1997, Ruth C. Green, Alice Kenitz, Joel G. Jorgensen, Stephen J. Dinsmore
Stephen J Dinsmore
Albino Eastern Bluebirds. On 24 July 1996, I banded two totally white Eastern Bluebirds in Sarpy County, Nebraska. These two birds were in a nest with two other normally plumaged siblings. They were not only white-plumaged, their feet and bills were white and the eyes were a pinkish-red. They were just as well developed as the two normal birds and were ready to fledge, which they did the following day. I believe these birds fit the description of total albinism as defined by John K. Terres in The Audubon Encyclopedia of North American Birds. He defines total albinism as the ...

Increased Abundance And First Breeding Record Of The Neotropic Cormorant (Phalacrocorax Brasilianus) On The Alluvial Plain Of Mississippi, Katie C. Hanson, Travis L. Devault, Stephen J. Dinsmore
Stephen J Dinsmore
Phalacrocorax brasilianus (Neotropic Cormorant) has been observed with increasing frequency in the alluvial plain (Delta region) of Mississippi. In the past 6 years, 22 individuals have been observed in 20 separate sightings during spring and summer. These sightings have occurred at breeding colonies of other colonial waterbirds and commercial aquaculture facilities of Ictalurus punctatus (Channel Catfi sh). Two sexually mature Neotropic Cormorants have been collected at a colonial waterbird breeding colony near the Mississippi River in the western Delta region among fl ocks of Phalacrocorax auritus (Double-crested Cormorants). Twice during the summer of 2008, confi rmed nesting of Neotropic Cormorants ...

Density, Abundance, And Habitat Associations Of The Inland Swamp Sparrow (Melospiza Georgiana Georgiana) In Iowa, Tyler Harms, Stephen J. Dinsmore
Stephen J Dinsmore
Wetlands continue to decline throughout North America and the Prairie Pothole Region, thus emphasizing the importance of understanding population trends and habitat associations of wetland species to ensure effective conservation and habitat management of those species. We estimated density and abundance and evaluated habitat associations of the Inland Swamp Sparrow (Melospiza georgiana georgiana) in Iowa. We conducted standardized distance sampling surveys for Swamp Sparrows and measured habitat characteristics at 307 wetlands in two regions of Iowa in 2009 and 2010. We used Program Distance to model detection probability and estimate region-specific breeding densities of Swamp Sparrows at Iowa wetlands. We ...
Habitat Associations Of Secretive Marsh Birds In Iowa, 2017 Iowa State University
Habitat Associations Of Secretive Marsh Birds In Iowa, Tyler Harms, Stephen J. Dinsmore
Stephen J Dinsmore
Drastic losses of wetland habitats across North America over the past century have resulted in population declines of many marsh birds therefore emphasizing the need for proper management of remaining wetlands for the conservation of marsh birds. Our objective was to evaluate the probability of site occupancy of secretive marsh birds in Iowa in response to habitat variables at multiple scales. We conducted call-broadcast surveys for eight species of marsh birds at wetlands in Iowa from 16 May–15 July 2009 and from 20 April–10 July 2010. We utilized occupancy models in Program MARK to estimate site occupancy probability ...
How Neural Activity Shapes Decision Making: An Optogenetic Investigation Of The Neural Basis Of Mate Choice In Female Songbirds, Sarah E. Maze
Honors Theses AY 16/17
The intent of this project is to gain new insight into the neural circuitry that underlies decision making through understanding the connection between sensory perception and motor action. This investigation further seeks to identify whether optogenetic manipulation of specific neurons results in a change in mate choice. In defining this connection, the end goal is to combat deleterious decision making behavior in humans, such as drug addiction. Female Bengalese finches (BFs) provide an accessible model in which to investigate the neural mechanisms of behavior. Previous studies reveal that activity in the caudal portion of the mesopallium (CM) in the female ...
Breeding Stage And Parentage Affect Tameness In Common Loons, 2017 Chapman University
Breeding Stage And Parentage Affect Tameness In Common Loons, Mina Ibrahim
Student Research Day Abstracts and Posters
Tameness is a measure of tolerance towards human disturbance. As human disturbance and recreational activity are increasing, it is becoming more and more important to understand responses of species to this disturbance. Tameness has been shown to be influenced by an individuals characteristics and life history. Two possible determinants of tameness are breeding stage and parentage. We studied tameness in common loons (Gavia immer) specifically looking at the effects of breeding stage and parentage. Tameness was measured by flight initiation distance (FID), the distance at which a loon dove from an approaching human observer in a canoe. Loons with chicks ...
Where In The World Are Pallas's Fish Eagles? Migration And Ecology Of Haliaeetus Leucoryphus In Asia, 2017 University of Arkansas, Fayetteville
Where In The World Are Pallas's Fish Eagles? Migration And Ecology Of Haliaeetus Leucoryphus In Asia, Marla Lynn Steele
Theses and Dissertations
Pallas’s Fish Eagle (Haliaeetus leucoryphus) is the Northern Hemisphere’s least understood eagle species. Virtually nothing is known concerning the species’ ecology. Historically, Pallas’s Fish Eagles were expected to breed in three separate populations in Mongolia, China, and India and was considered one of the most common raptors in Asia prior to the 1900’s. However, by 1960’s major declines were observed. The species is currently listed as “globally vulnerable” by the International Union for the Conservation of Nature (IUCN) Red List. The current study examined over a century of Pallas’s Fish Eagle observation data to ...
Heterogeneity Of Avian Breeding Habitat On Grazing Lands Of The Northern Great Plains, 2017 University of Nebraska-Lincoln
Heterogeneity Of Avian Breeding Habitat On Grazing Lands Of The Northern Great Plains, Maggi S. Sliwinski
Dissertations & Theses in Natural Resources
Native rangelands in the Great Plains are largely privately owned and used for beef production. Vegetation heterogeneity is important for maintaining biodiversity, but private land may be more homogenous than desired. My research had two components: 1) to examine whether a variety of grazing strategies created vegetation heterogeneity in a large, intact rangeland, and 2) to understand beef producers’ attitudes about vegetation heterogeneity.
First, I sampled vegetation structure, composition, and bird abundance at multiple plots on eleven management units in Cherry County, Nebraska. Units were managed with commonly used grazing strategies (e.g., short-duration grazing and season-long continuous grazing). I ...
Preferred Atmospheric Patterns For Vernal And Autumnal Nocturnal Bird Migration Using The Plymouth, New Hampshire Noaa-Esrl Snow Level Radar, Andrea Larocca, Careyanne Howlett, Parker Bradley, Jesse Carlson
Student Showcase of Excellence
Radar technology can be a useful tool in tracking trends in bird migration. The NOAA-ESRL Snow Level Radar (SLR), located in Plymouth, New Hampshire, is primarily used to monitor the Bright-Band Height (BBH) of falling precipitation, or the level at which snow melts to water. Using data collected from November 2014 to November 2016, preferential atmospheric conditions over Plymouth, New Hampshire were analyzed during peak migration events for both autumn and spring migration seasons.
Habitat Restoration Through Permaculture And Agroforestry In Southern Belize, 2017 Environmental Biology
Habitat Restoration Through Permaculture And Agroforestry In Southern Belize, Parker Bradley, Alexandra Hill, Lucas Kirker, Andrew Van Houten, Jared Lamy, Jason Kenney, Logan Kuzmitch
Student Showcase of Excellence
One of the major benefits of permaculture and agroforestry is the restoration of complex habitat while still providing calories for human consumption. The Maya Mountain Research Farm in Southern Belize consists of 32ha of former cattle pasture and citrus orchard now used for permaculture and agroforestry, hosting a diverse polyculture of dozens of fruit-bearing tree and shrub species and about half a dozen timber tree species, all interspersed with dynamic patches of banana and maize. Spread out along the farm’s habitat mosaic, 17 point count stations were repeated three times, as well as 21 forest interior stations done once ...
Changes In The Breeding Range Of The Broad-Winged Hawk (Buteo Platypterus) Due To Habitat Fragmentation In The Northern Appalachian Region, Rachael M. Pruitt
The Broad-winged Hawk (BWHA), Buteo platypterus, a small, secretive hawk with distinguishing broad black tail bands, breeds in northeastern North America. The hawks nest in deciduous or mixed forest, often near water, and close to clearings or forest edges. Land conversion and fragmentation alters the landscape and reduces the area of contiguous forest used by BWHA. This study seeks to determine the habitat metrics that may be influencing the apparent breeding range declines of the BWHA at the landscape scale. Landscape characteristics and BWHA presence data from 18,684 Breeding Bird Atlas blocks (each about 25km2) from Ohio, West Virginia ...
