Winter Field Report, December 2019-February 2020, W. Ross Silcock

Nebraska Bird Review

As with any of these Seasonal Reports, there was plenty to entertain us and to contemplate this winter. The most obvious feature of this winter’s reports was the taxonomically widespread incidence of midwinter occurrences of species normally absent at that time. Snow, Ross’s, and Greater White-fronted Geese occurred in good numbers, and Jan to early Feb reports of dabbling and diving ducks often far from expected winter occurrence locations were notable. Among passerines, notable midwinter reports were of Gray Catbird, Brown Thrasher, and Northern Mockingbird, Nebraska’s first record for Feb of American Pipit, and 6th winter record of Lesser Goldfinch. …

2019-2020 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Mergansers reached a new high of 104 counted in nine circles, which topped the count of 97 from 2017. A single Surf Scoter was found in the Lower Platte circle, which was only the fourth time that this species has been found on a Nebraska CBC. Lone birds were also found at Lake McConaughy in 1999, 2010 and 2015. A good North Platte find were two Barrow’s Goldeneye. Several species, however, were counted in numbers much below the norm. The lone Wood Duck found at Branched Oak was the lowest count for that species since 2004, when they were missed …

Impacts Of Invasive Rats On Hawaiian Cave Resources, Francis G. Howarth, Fred D. Stone

International Journal of Speleology

Although there are no published studies and limited data documenting damage by rodents in Hawaiian caves, our incidental observations during more than 40 years of surveying caves indicate that introduced rodents, especially the roof rat, Rattus rattus, pose significant threats to vulnerable cave resources. Caves, with their nearly constant and predictable physical environment often house important natural and cultural features including biological, paleontological, geological, climatic, mineralogical, cultural, and archaeological resources. All four invasive rodents in Hawai‘i commonly nest in cave entrances and rock shelters, but only the roof rat (Rattus rattus) habitually enters caves and utilizes areas …

Assessing Population Genetic Structure Of Eastern Phoebes At A Migratory Stopover Site, Daniel Jones

Biology Theses

Migration is an energetically costly and stressful event and migratory stopover sites are important areas along the migratory route that birds stop at to rest and refuel. Migration timing and routes vary across and even within species, including differences between sexes, ages and populations. Most genetic studies of migratory birds occur on breeding grounds, but when breeding locations are not known, it is likely that genetic patterns can be assessed accurately at migratory stopover sites if certain conditions exist. First, if a species is philopatric – where individuals return to the same sites every year, gene flow across geographically separated …

Bird Community Monitoring At Tallgrass Prairie National Preserve, Kansas, Status Report 2001–2018, David G. Peitz, Kathleen A. Kull

United States National Park Service: Publications

Executive Summary

In 2001, the Heartland I&M Network initiated breeding bird surveys on Tallgrass Prairie National Preserve, Kansas, to assess the ecological integrity of the preserve’s habitat. Birds are an important component of ecosystems and can serve as good indicators of habitat change in an ecosystem. In the 17 years of bird surveys at the preserve (2001 to 2018, excluding 2003), there were 2,089 plot visits and 119 different bird species recorded, 96 of which have the potential to breed within the preserve. These 96 species represent approximately 81% of the total species one would reasonably expect to have breeding …

The Effects Of Dietary Linoleic Acid And Hydrophilic Antioxidants On Basal, Peak, And Sustained Metabolism In Flight‐Trained European Starlings, Wales A. Carter, Kristen J. Demoranville, Barbara J. Pierce, Scott R. Mcwilliams

Biology Faculty Publications

Dietary micronutrients have the ability to strongly influence animal physiology and ecology. For songbirds, dietary polyunsaturated fatty acids (PUFAs) and antioxidants are hypothesized to be particularly important micronutrients because of their influence on an individual's capacity for aerobic metabolism and recovery from extended bouts of exercise. However, the influence of specific fatty acids and hydrophilic antioxidants on whole‐animal performance remains largely untested. We used diet manipulations to directly test the effects of dietary PUFA, specifically linoleic acid (18:2n6), and anthocyanins, a hydrophilic antioxidant, on basal metabolic rate (BMR), peak metabolic rate (PMR), and rates of fat catabolism, lean catabolism, and …

Insights About Diversity Of Tetrabothriidae (Eucestoda) Among Holarctic Alcidae (Charadriiformes): What Is Tetrabothrius Jagerskioeldi?, Eric P. Hoberg, Kaylen Marie Soudachanh

MANTER: Journal of Parasite Biodiversity

Tetrabothriid cestodes are characteristic helminths that infect species of seabirds globally. We begin with the exploration of the diversity of tapeworms of the genus Tetrabothrius Rudolphi, 1819 (Eucestoda: Tetrabothriidae), some of which are distributed among seabirds of the family Alcidae (Charadriiformes) at boreal to higher latitudes of Holarctic seas. During the course of 2 decades of field inventory from 1975 through the early 1990s (in addition to earlier collections assembled by Robert L. Rausch and colleagues in Alaska initiated in the late 1940s), an extensive series of tapeworm specimens attributable to species of Tetrabothrius was recovered from seabirds across the …

The Whelming Sea, Sean Hanley

Theses and Dissertations

The Whelming Sea is a thirty-minute experimental documentary that reveals the moments of entanglement between three animals living along the Mid-Atlantic shoreline; curious humans, spawning horseshoe crabs, and migratory shorebirds. Working from the realm of multispecies ethnography, the film shifts the subjective positioning of the viewer between the human and nonhuman to suggest the complexity of our enmeshed experience. In the face of this current era of mass extinction, the film explores the limitations and poetic possibilities of scientific encounters with the lives of others.

Resistance And Resilience Of Virgin Islands Bird Populations Following Severe Hurricanes, Robert A. Askins, David N. Ewert

Biology Faculty Publications

We analyzed changes in abundance of terrestrial birds on St. John, U.S. Virgin Islands, for a 32 year period during which 3 major hurricanes occurred. Using 1987 as a baseline year, because it followed a 27 year hiatus when no major hurricanes hit the island, we assessed the impact of hurricanes on vegetation structure and bird populations. Bird abundance was determined for 25 m radius circular plots that were surveyed each year of the study along the same transects. Percent cover of trees, shrubs, and herbs was measured in each plot in 1987, 1990, and 2019. All of the survey …

Possible Role Of Breeding Phenology, Brood Size, And Male Parental Care On The Number Of Nesting Attempts By Female Eastern Bluebirds, A Facultatively Multibrooded Species, Michael Daniel Patton

Online Theses and Dissertations

To maximize reproductive output, several species of songbirds attempt to raise two or more broods in a single breeding season. The results of previous studies have revealed much variation among species in the factors that influence the likelihood of female songbirds attempting to raise multiple broods during a breeding season. As such, additional studies are needed to better understand the roles of early breeding, brood sizes, and, especially, male parental care in determining the likelihood of having multiple broods. My objective, therefore, was to examine the possible effects of breeding initiation date, brood size, and male provisioning behavior on the …

Investigating The Avian Species Composition, Diversity, And Abundance Of Engelhorn Pond, Kiana Rose

Undergraduate Honors Theses

Central Washington University’s Engelhorn Pond contains important habitats for many organisms, particularly migratory birds, and is a valuable resource for students. However, little information is available about the wildlife inhabiting the pond. The pond’s discrete location means that many people are unaware of its existence. In addition, the pond is threatened by a number of anthropogenic sources, including chemical runoff, garbage, and feral cats. By using point counts, a common ornithological survey technique, I recorded the bird species present at the pond during all seasons of the year. I collected data using point counts during 13 visits from June of …

Spring Field Report, March-May 2020, W. Ross Silcock

Nebraska Bird Review

Although there were numerous early arrival dates, most were in the range of historically earliest expected dates; notable, however, was a lone record-early Whiterumped Sandpiper, nicely photographed. Record late by a month was a juvenile Redtailed (Harlan’s) Hawk, also confirmed by photo. Perhaps most prominent this spring were the large numbers of several species. Most eye-popping were record spring totals of 22 Glossy Ibises, 11 Yellow-bellied Flycatchers, 14 Veeries, including five in the Panhandle, 48 Gray-cheeked Thrushes, 20 Bay-breasted Warblers, not long ago a rare bird in spring, 45 Golden-winged Warblers and 27 Canada Warblers, both of which were about …

Using Bioenergetics And Radar-Derived Bird Abundance To Assess The Impact Of A Blackbird Roost On Seasonal Sunflower Damage, Bonne A. Clark, Page E. Klug, Phillip M. Stepanian, Jeffrey F. Kelly

Human–Wildlife Interactions

Methods aimed at reducing avian damage to agricultural crops are routinely implemented in situations where efficacy can be assessed by quantifying blackbird (Icteridae) abundance relative to environmental variables and extrapolating to ensuing crop damage. Concomitantly, Weather Surveillance Radar (WSR) data may have potential to enhance crop damage mitigation through improved monitoring of nuisance wildlife populations. We used WSR to derive daily abundance estimates of blackbirds at a fall roost in North Dakota, USA from 2012 to 2019. We integrated these estimates with previously developed bioenergetics-economic models to estimate local sunflower (Helianthus annuus) damage. The greatest losses usually occurred …

Effects Of Slope Upon Hind Limb Kinematics In Chukar Partridge (Alectoris Chukar), Anna T. Kenney

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Ground dwelling birds must scale all kinds of complex terrain in order to survive in their natural environments. For instance, Alectoris chukar live on steep hillsides with slopes of up to 60° or 172.3% slope. We undertook the present study to improve understanding of how birds successfully traverse such complex terrain. Using a high speed camera, we analyzed the hind limb kinematics of chukars during normal locomotion on a 10° and 35° incline, decline, and level slope. We compared the data collected from the video recordings, which we had used to identify and digitize the bony landmarks, between all conditions. …

Understanding How Agricultural Intensification Impacts Ring-Necked Pheasant Distribution And Survival In Eastern South Dakota, Hilary R. Kauth

Electronic Theses and Dissertations

Historically, pheasants (Phasianus colchicus) have thrived in South Dakota in conjunction with successful land retirement programs or early farming practices through the 1950s, which created interspersions of agriculture and native landscapes that were ideal for pheasants. Recently, the Prairie Pothole ecosystem has undergone rapid agroeconomic expansion, effectively reducing ideal interspersions of native prairie and cropland into agriculturally homogeneous landscapes. Indices of pheasant abundance have suggested persistent population declines since 2008, raising concerns regarding landscape suitability. Our goal was to understand how agriculture intensification impacts pheasant ecology. The objectives were to: 1) estimate overwinter hen probability of survival, resource …

The Effect Of Shade Tree Species On Bird Communities In Central Kenyan Coffee Farms, Deven Kammerichs-Berke

Cal Poly Humboldt theses and projects

Shade coffee has been recognized as a well-studied example of a land-sharing management strategy that both creates habitat for tropical birds while also maintaining agricultural yield. Despite the general consensus that shade coffee is more “bird-friendly” than a sun coffee monoculture, little work has been done to investigate the effects of specific shade tree species on bird diversity and their capacity to help deliver ecosystem services. Previous studies in temperate regions have demonstrated that due to shared evolutionary histories, native plant species are better at promoting native arthropod numbers, which in turn support a greater number of birds. This study …

Phenotypic Divergence In Two Sibling Species Of Shorebird: Common Snipe And Wilson’S Snipe (Charadriiformes: Scolopacidae), Tiago M. Rodrigues, Edward H. Miller, Sergei V. Drovetski, Robert M. Zink, Jon Fjeldså, David Gonçalves

School of Biological Sciences: Faculty Publications

Natural and social selection are among the main shapers of biological diversity but their relative importance in divergence remains understudied. Additionally, although neutral evolutionary processes may promote phenotypic divergence, their potential contribution in speciation is often overlooked in studies of comparative morphology. In this study, we investigated phenotypic differentiation in two allopatric shorebirds: the Palaearctic Common Snipe Gallinago gallinago and the Nearctic Wilson’s Snipe Gallinago delicata. Specimens of Common Snipe (n = 355 skins, n = 163 skeletons) and Wilson’s Snipe (n = 403 skins, n = 141 skeletons) in natural history collections were examined to quantify differences in skeletal …

Daily Energy Expenditure Of Florida Scrub-Jays (Aphelocoma Coerulescens) In Suburban And Wildland Landscapes, Hugh I. Ellis, Reed Bowman

Biology: Faculty Scholarship

Urbanization alters ecological systems, disturbance regimes, food webs, and a variety of other processes that can influence local flora and fauna. In birds, most studies have focused on behavioral or demographic responses to altered conditions; however, the physiological mechanisms associated with these responses have been understudied. We have previously documented shifts in foraging behavior because of the availability of human-provided food; we sought to see if this was driven by or associated with a change in field metabolic rates. We measured field metabolic rates (FMR), a measure of daily energy expenditure (DEE), of Florida Scrub-Jays (Aphelocoma coerulescens) in 2 habitats …

Sharp‐Tailed Grouse In The Nebraska Sandhills Select Residual Cover Patches For Nest Sites, William L. Vodehnal, Gregory L. Schenbeck, Daniel W, Uresk

Nebraska Game and Parks Commission: Staff Research Publications

We evaluated selection and availability of residual cover (dead standing herbage) by sharptailed grouse (Tympanuchus phasianellus) at time of nest‐site selection in an intact and annually grazed grassland. We used radiotelemetry in 1988–1990 to locate 147 nests in the sandhills of Nebraska, USA, and classified 121 as initial nests and 26 as renests. We used visual obstruction readings (VOR) to measure the height and density of residual cover at nests and 373 landscape‐scale transects around leks (trap sites). We excluded 77 nests from vegetation analysis because green herbage or early livestock grazing compromised residual cover measurements. Most females …

Winter Patch Grazing, Patch Burn Grazing, And Bird Communities In Western South Dakota, Jennifer Lutze

Electronic Theses and Dissertations

Ground nesting bird species are on a considerable decline and research efforts are being made to increase these populations throughout the Great Plains. Ground nesting bird communities found in the Northern Great Plains are driven greatly by varying amounts of cover and area size. Past research implemented patch-burn grazing to increase structural heterogeneity and to increase grassland bird habitat in the tallgrass prairie. While bird populations were very responsive to this management in the Northern Great Plains fire management is viewed negatively, especially for Midwest cattle ranchers. We implemented research to determine if winter-patch grazing on mixed grass prairie could …

The Role Of Melatonin In Biological Rhythms Of Songbirds, Clifford E. Harpole

Theses and Dissertations--Biology

In vertebrates, melatonin is a hormone that is produced and secreted at night and inhibited by light. This unique “darkness-only” expression profile makes it an intellectually appealing candidate for a means of transmitting temporal information to an individual, both time of day and time of year.

In passerine birds, “time of day” information is certainly transmitted via melatonin secretion. The primary producer of systemic melatonin in this family of birds is the pineal gland, and surgical removal of it causes a bird to become arrhythmic in constant conditions. I find that as pinealectomized house sparrows (Passer domesticus) become …
