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 …

Unusual Bird Reports From The Trans-Pecos District Of Chihuahua, Mexico, Including Five New Additions To The State Of Chihuahua, Israel Moreno-Contreras, Fernando Mondaca-Fernández, Daniel Enrique Pérez-Carrillo, José Manuel Jurado-Ruiz, María Cristina Pérez-Amezola, Marisa Tirado-Madrid, William H. Howe

Western North American Naturalist

We present new distributional information on 21 species of birds from the state of Chihuahua, Mexico, 5 of which represent the first documented records for this state. Several observations are of birds normally associated with the Sierra Madre Occidental province, suggesting that these species may be regular wanderers to the Trans-Pecos district of Chihuahua.

Nuestras observaciones adicionales son de aves asoci­adas con la provincia de la Sierra Madre Occidental, sin embargo, estos registros sugieren que estas especies …

Habitat Characteristics And Winter Use Of Woodpecker-Excavated Tree Cavities, Adrianna Yoder

2023 Midwest Ecology & Evolution Conference

Avifauna are in decline in North America, including red-headed woodpeckers (Melanerpes erythrocephalus). Red-headed woodpeckers are negatively impacted by urbanization, which has decreased their ideal habitats of oak-savannas and through the management of urban trees there has been a reduction in the amount of tree decay, a necessary feature of suitable trees that woodpeckers can make cavities in. Cavities are created and used as nests in the breeding season (spring/summer) and as roost-sites in the non-breeding season (fall/winter). In the Chicagoland region, during the fall some red-headed woodpeckers migrate while others do not and remain overwinter, making them facultative …

Increasing Capture Rates Of Grassland Birds Over Thirteen Years Indicates Successful Restoration, Katie Stumpf, Charles Muise

Georgia Journal of Science

Grassland bird populations are being lost at an alarming rate due to human modifications to grassland ecosystems. Grassland restoration has been shown to mitigate population declines for many species that use these habitats at some point in their annual cycles. We examined capture rates of adult, breeding, and hatch-year birds at a restored grassland site in the piedmont of central Georgia to determine whether colonization, breeding success, hatching success, and recruitment processes were impacting populations of grassland birds. We banded birds approximately twice per month from January 2009 through December 2021 at Panola Mountain State Park. Restoration efforts started in …

2022-2023 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Sixteen counts were run in the 2022-2023 CBC season. Because of weather and rescheduling issues, the Crawford, Harrison, and Harlan County counts were cancelled. Eight of the counts were completed during the first week of the count period and the other eight were scattered throughout the remainder of the count period. An early December cold snap seemed to drive many of the birds south, but the weather on actual count days was fairly benign: mostly dry with an average high of 34˚F and an average low of 19˚F and with three circles reporting light snow. The total number of species …

Winter Field Report, Dec. 2022 - Feb. 2023, W. Ross Silcock

Nebraska Bird Review

Since this is a Winter Seasonal Report, it seems appropriate to lead off with notable reports of occurrences that might be considered unexpected for midwinter, of which there were several. A range of species was involved, suggesting an encompassing cause such as climate change. Of interest were northerly wintering groups of waterfowl including Gadwall, Green-winged Teal, Canvasback, Ringnecked Duck, and Hooded Merganser. Reports of wintering Tundra Swans, Whitewinged Doves, and Lesser Goldfinches continue to increase, and numerous Redwinged Blackbirds in the northeast in midwinter were unexpected. Also quite unexpected were two Sandhill Cranes wintering in the east, the state’s first …

Remembering Paul Johnsgard, Linda R, Brown, Josef Kren

Zea E-Books Collection

Paul A. Johnsgard (1931–2021) was a friend of many, an artist, prolific author, teacher, and humble admirer of all living creatures. It was impossible to find someone at Nebraska Audubon Society or Nebraska Ornithologists’ Union meetings who did not know Paul Johnsgard. His more than 100 published books made him known not just in a community of ornithologists, birdwatchers, and bird lovers in the United States but also abroad. He was a world-renowned ornithologist and naturalist who remained deeply embedded in his local culture and its prairie environment.

We invited about 75 people to write a short memory of Paul. …

The Strength Of Migratory Connectivity In Painted Buntings Is Spatial Scale Dependent And Shaped By Molting Behavior, Andrew J. Sharp, Andrea Contina, Viviana Ruiz-Gutiérrez,, T. Scott Sillett, Eli S. Bridge, Elizabeth M. Besozzi, John A. Muller, Jeffrey Kelly, Aaron M. Given, Clark S. Rushing

School of Integrative Biological & Chemical Sciences Faculty Publications

As migratory species move through the stages of their annual cycle, individuals often display variation in the degree to which they remain in proximity to one another, a phenomenon called migratory connectivity. We show scale dependence in the strength of migratory connectivity in Painted Buntings (Passerina ciris), a North American passerine with disjunct eastern and interior breeding populations. Based on light-level geolocator data from 112 individuals at 11 breeding sites, migratory connectivity between breeding and wintering grounds was strong at the range-wide scale, with interior and eastern Painted Buntings remaining separated throughout the annual cycle. Conversely, migratory connectivity …

Does Bergmann’S Rule Apply To North American Birds In The Context Of Climate Change?, Peridot Derrin Galloway

Student Theses and Dissertations

Over the past half century, birds have changed, including in their morphology. Biogeographic rules including Bergmann’s and Allen’s rules have been used to try to elucidate morphological changes; however, there has been dispute over the rules’ applicability. Thus, I aimed to identify 1) morphometric trends over time of 15 North American bird species, including eastern bluebirds (Sialia sialis); 2) if these morphometric trends follow Bergmann’s rule; and 3) if the observed morphometric trends are associated with life history and other traits, as well as climatic variables (e.g., average, maximum and minimum temperatures, and total precipitation). Using short- and long-term morphological …

Territorial Intrusion By Resident Male Wilson's Warblers: Breeding Stages Of The Intruders And Distances They Travel, William M. Gilbert

Western North American Naturalist

It now is generally recognized that genetic monogamy is the exception in birds, and that extrapair paternity in territorial species requires that one or the other sex involved in such an extrapair mating travel off its own territory to obtain an extrapair copulation. However, which sex or sexes travel off their home territories, the distances they might travel to obtain extrapair copulations, and the breeding stages during which they might make such off-territory forays are poorly understood for most species. I explored these issues in Wilson’s Warblers (Cardellina pusilla) in central, inner-coastal California. Male Wilson’s Warblers frequently intruded …

Winter Connectivity And Leapfrog Migration In A Migratory Passerine, Rafael Rueda‐Hernández, Christen M. Bossu, Thomas B. Smith, Andrea Contina, Ricardo Canales Del Castillo, Kristen Ruegg, Blanca E. Hernández-Baños

School of Integrative Biological & Chemical Sciences Faculty Publications

Technological advances in migratory tracking tools have revealed a remarkable diversity in migratory patterns. One such pattern is leapfrog migration, where individuals that breed further north migrate to locations further south. Here, we analyzed migration patterns in the Painted Bunting (Passerina ciris) using a genetic‐based approach. We started by mapping patterns of genetic variation across geographic space (called a genoscape) using 386 individuals from 25 populations across the breeding range. We then genotyped an additional 230 samples from 31 migration stopover locations and 178 samples from 16 wintering locations to map patterns of migratory connectivity. Our analyses of …

Genetic And Ecological Drivers Of Molt In A Migratory Bird, Andrea Contina, Christen M. Bossu, Daniel Allen, Michael B. Wunder, Kristen Ruegg

School of Integrative Biological & Chemical Sciences Faculty Publications

The ability of animals to sync the timing and location of molting (the replacement of hair, skin, exoskeletons or feathers) with peaks in resource availability has important implications for their ecology and evolution. In migratory birds, the timing and location of pre-migratory feather molting, a period when feathers are shed and replaced with newer, more aerodynamic feathers, can vary within and between species. While hypotheses to explain the evolution of intraspecific variation in the timing and location of molt have been proposed, little is known about the genetic basis of this trait or the specific environmental drivers that may result …

Avian Community Response To Oak Savanna Management In West Michigan, Abigail Elaine Fischer, Paul W. Keenlance, Alexandra B. Locher, Joseph J. Jacquot

Masters Theses

In the midwestern United States, oak savanna ecosystems have experienced steep declines over the past century due to loss of disturbances and changes in land use. This loss coincides with the decline in avian communities across North American and has negatively impacted taxa that associate with open vegetation cover types. Expanding efforts to restore and manage oak savanna ecosystems has resulted in increased open habitat which has positively impacted these avian communities, resulting in increased species diversity. While numerous studies within the Midwest have observed similar results, there have been no studies in Michigan that have formally assessed the impact …

Sense-Able Hauntings: Ethics And Narratives In Ornithological Specimen Preservation At Yale's Peabody Museum, Elaina Foley

Kaplan Senior Essay Prize for Use of Library Special Collections

Until I was standing in between the rows of towering metal specimen cabinets, I didn’t understand how many birds the Yale Peabody Museum holds. Like most people, I had only experienced the display side of museums: its dioramas and glass cases. These displays, while made to embody a certain set of interests, priorities, and values, still serve an obscuring function—they vastly underrepresent the museum’s total collections. In their ornithology collection alone, the Peabody currently holds more than 152,000 bird skins, bones, eggs, nests, and other avian fragments. The Peabody staff members who maintain the ornithology specimen collections are distinct from …

Can The Food Preparation Hypothesis Account For Anting Behavior In Birds?, Ella Brady

2023 REYES Proceedings

This report discusses the food preparation hypothesis, one of several proposed hypotheses to explain anting behavior in birds. A brief review of the theory’s history and development, as well as an assessment of evidence for and against such a function of anting, is provided. Although there are indeed experimental data supporting food preparation as the purpose of anting behavior, there is also conflicting evidence which complicates the theory. Ultimately, it is suggested that food preparation is a secondary function of anting – a pleasant but latent “side effect” achieved alongside the behavior’s primary purpose, which is still unknown.
