Characteristics, Contexts, And Possible Functions Of The Vocalizations Of Blue Jays, Dustin Eric Brewer

Online Theses and Dissertations

Many species in the family Corvidae, including Blue Jays (Cyanocitta cristata), are known to have large vocal repertoires. However, perhaps due to its perceived complexity, few investigators have attempted to describe the vocal repertoire of Blue Jays. Therefore, my objectives were to describe the vocal repertoire of Blue Jays, determine the characteristics of their calls, and suggest possible functions. During 2015 and 2016, I studied free-living Blue Jays in and near Richmond, Madison County, Kentucky. I observed Blue Jays at 17 different locations, recorded their vocalizations, and noted the behavioral contexts during which calls were uttered. I also conducted playback …

The Nutritional Value Of Fecal Sacs: Testing The Parental Nutrition Hypothesis, Amanda W. Burns

College of Graduate Studies: Theses & Dissertations

Nest sanitation is an important aspect of parental investment in birds with altricial nestlings. Passerine nestlings produce fecal matter that is encased in a mucous membrane for easy disposal. These fecal sacs are either removed from the nest and transported a distance away or they are ingested by the adult. A decline in fecal sac ingestion rates as nestlings age has been observed in several species. The parental nutrition hypothesis posits that this pattern can be attributed to increasing digestive efficiency as nestlings age. The parental nutrition hypothesis makes three predictions: fecal sac consumption rates should decrease as nestlings age, …

Territorial Defense Strategies In The Northern Cardinal (Cardinalis Cardinalis): Who Is The Bigger Threat?, Kaylee M. Gentry

Master's Theses

This thesis examines the use of defensive strategies in relation to territories year round in the northern cardinal (Cardinalis cardinalis). Responses to recorded neighbor song and stranger song playback from the middle of a focal male’s territory were measured. This allowed for an estimation of aggression in both the winter and spring seasons. Each focal male was subjected to both treatments (stranger song and neighbor song). Males were more responsive over-all to neighbor song playback, however in the winter months, persistence of response to neighbor song playback increased. It was also shown that southeastern United States cardinals show …

Heat Dissipation During Hovering And Forward Flight In Hummingbirds, Don Powers, Bret W. Tobalske, J. Keaton Wilson, Keeley R. Corder

Faculty Publications - Department of Biological & Molecular Science

Flying animals generate large amounts of heat, which must be dissipated to avoid overheating. In birds, heat dissipation is complicated by feathers, which cover most body surfaces and retard heat loss. To understand how birds manage heat budgets during flight, it is critical to know how heat moves from the skin to the external environment. Hummingbirds are instructive because they fly at speeds from 0 to more than 12ms−1, during which they transit from radiative to convective heat loss. We used infrared thermography and particle image velocimetry to test the effects of flight speed on heat loss from specific body …

2015 Fall Migration Bird Banding At Wildcat Hills State Recreation Area, Holly Garrod

Nebraska Bird Review

It was a different season of bird banding this year at Wildcat Hills State Recreation Area in Scotts Bluff County, Nebraska. Due to construction at the nature center, the banding station was moved farther down the road to one of the picnic shelters. The habitat remained mostly the same, with Ponderosa Pine and multispecies-shrub understory dominating the unique ridge landscape characteristic of Wildcat Hills. The new site provided more shrub understory but lacked the running water of Turkey Creek and the bird feeders at the nature center. Bird Conservatory of the Rockies (formerly Rocky Mountain Bird Observatory) has been banding …

Fall Field Report, August–November 2015, W. Ross Silcock

Nebraska Bird Review

To start, a housekeeping item: in the species accounts that follow, whenever I use the term "migrant" I am referring to fall migration only. Many species, of course, have differing migration strategies and timing in spring and fall.

Much of the data used in this report relating to western and Pine Ridge passerines comes from the outstanding banding efforts by Bird Conservancy of the Rockies (formerly Rocky Mountains Bird Observatory) at Chadron State Park (CSP) and Wildcat Hills Nature Center (WHNC) in Scotts Bluff Co. This year’s operators were Josh Lefever and Holly Garrod. Related to the Chadron State Park …

Failure Of A Heterologous Recombinant Sca5/Ompb Protein-Based Vaccine To Elicit Effective Protective Immunity Against Rickettsia Rickettsii Infections In C3h/Hen Mice, Sean P. Riley, Marissa M. Cardwell, Yvonne G. Chan, Ludovic Pruneau, Fabio Del Piero, Juan J. Martinez

Faculty Publications

Spotted fever group (SFG) rickettsial species are obligate intracellular tick-borne pathogens that are responsible for important human diseases. Previous reports have demonstrated the feasibility of using recombinant surface cell antigen Sca5/OmpB to elicit protective immunity against homologous challenges using murine models of Mediterranean spotted fever and Rocky Mountain spotted fever. In addition, the feasibility of generating cross-protective immunity against related rickettsial species has also been established, but the molecular basis for these phenomena was not explored. Here, we demonstrate that vaccination of C3H/HeN mice with a recombinant OmpB domain derived from Rickettsia conorii induced high titer humoral immune responses that …

Gut Microbiota Of Migratory Passerines At Stopover, William Bagley Lewis

Master's Theses

Although the gut microbiota provides many beneficial functions to animal hosts, relatively little is known about the gut microbiota of passerines. It is likely that gut microbes are especially important during the migratory phase; however gut atrophy experienced during prolonged migratory flight may cause disruptions of the stable microbiota. Fecal samples were collected from several species of passerine after crossing the Gulf of Mexico during spring migration and before crossing during fall, and microbiota communities were analyzed using next-generation sequencing. Despite showing large inter-individual variation, a core microbiota composed largely of Firmicutes and Proteobacteria was identified in all birds. Microbiota …

Effects Of Wind Turbine Noise On Male Greater Prairie-Chicken Vocalizations And Chorus, Cara E. Whalen

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

Wind energy facilities are constructed without full knowledge of their effects on birds, and the noise generated by wind turbines is a particular concern. I investigated the effects of wind turbine noise on male Greater Prairie-Chicken (Tympanuchus cupido pinnatus) vocalizations and chorus near Ainsworth, NE, USA in 2013 and 2014. I studied 14 leks located in the area surrounding a 36-turbine wind energy facility. I used two main approaches in this study. First, I recorded Greater Prairie-Chicken boom, cackle, whine, and whoop vocalizations at each of the study leks and measured the duration, sound pressure level, peak frequency, …

Occupancy Analysis And Density Estimation Of Kori Bustards (Ardeotis Kori) And Helmeted Guineafowl (Numida Meleagris) For Use In Landscape Conservation Planning In The Northern Tuli Game Reserve, Botswana, Kathryn R. Mccollum

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

For understudied species, more informed conservation planning and decision-making on both the local and landscape levels may be attained through the use of occupancy and abundance estimations. Here, we focus on two iconic bird species in eastern Botswana, kori bustards (Ardeotis kori) and helmeted guineafowl (Numida meleagris). The overall goal of this project was to better understand the hierarchy of factors that influence occupancy (ψ) and density of kori bustard and helmeted guineafowl populations within the Northern Tuli Game Reserve and how these factors may interact to affect landscape conservation and usage. We performed distance sampling …

Displaying To Females May Lower Male Foraging Time And Vigilance In A Lekking Bird, Sarah A. Cowles, Robert M. Gibson

School of Biological Sciences: Faculty Publications

Males of many species use courtship behavior to attract mates. However, by doing so males may face the associated costs of increased energetic expenditure, reduced foraging time, and elevated predation risk. We investigated the costs of display in lekking male Sharp-tailed Grouse (Tympanuchus phasianellus). We used lek-wide scan sampling to study how males allocated time among courtship display (‘‘dancing’’), agonism, foraging, and inactivity in relation to female numbers both within and across days. We also addressed the limited attention hypothesis and estimated visual attentiveness by videotaping 13 males and scoring head turns during these different activities. We found that the …

Predicting Toucan Locations In Panama Using Arcgis, Daniel J. Herrera

Geography: Student Scholarship & Creative Works

Toucans are omnivorous birds native to southern Latin America and South America. They are non-migratory, and their range is disputed among experts. In an attempt to develop a better understanding of the range and behavior of toucans, correlations between toucan presence and geographic features of the area were analyzed to create a location probability map.

King Penguins Can Detect Two Odours Associated With Conspecifics, Gregory B. Cunningham, Francesco Bonadonna

Biology Faculty/Staff Publications

Recent studies on olfaction in penguins have focused on their use of odours while foraging. It has been proposed for some seabirds that an olfactory landscape shaped by odours coming from feeding areas exists. Islands and colonies, however, may also contribute to the olfactory landscape and may act as an orienting map. To test sensitivities to a colony scent we studied whether King penguins (Aptenodytes patagonicus) could detect the smell of sand, feathers or feces by holding presentations beneath their beaks while they naturally slept on the beach. Penguins had a significantly greater response to the feathers and feces presentations …

Breeding Birds Of Virginia, Bryan D. Watts

Virginia Journal of Science

Virginia supports a diverse community of breeding birds that has been the focus of investigation for more than 400 years. The avifauna reflects the latitudinal position of the state and the fact that the border extends from the Atlantic Ocean to the Appalachian Mountains. A total of 224 species have been recorded breeding in Virginia, 214 of which are extant. Twenty species have colonized the state since 1900 including 14 since 1950. Of all extant species, 102 (48%) are considered common at least somewhere in the state and 64 (30%) are rare to very rare. Diversity varies by physiographic region …

Temporal Variability And Cooperative Breeding: Testing The Bet-Hedging Hypothesis In The Acorn Woodpecker, Walter D. Koenig, Eric L. Walters

Biological Sciences Faculty Publications

Cooperative breeding is generally considered an adaptation to ecological constraints on dispersal and independent breeding, usually due to limited breeding opportunities. Although benefits of cooperative breeding are typically thought of in terms of increased mean reproductive success, it has recently been proposed that this phenomenonmay be a bet-hedging strategy that reduces variance in reproductive success (fecundity variance) inpopulations living inhighly variable environments. We tested this hypothesis using long-term data on the polygynandrous acorn woodpecker (Melanerpes formicivorus). In general, fecundity variance decreased with increasing sociality, at least when controlling for annual variation in ecological conditions. Nonetheless, decreased fecundity variance …

The Effects Of Urbanization On Tick Parasitism Rates In Birds Of Southeastern Virginia, Erin Leigh Heller

Biological Sciences Theses & Dissertations

The coastal region of southeastern Virginia is one of the largest urban areas along one of North America’s migratory flyways. Because hundreds of avian species use this flyway, understanding factors affecting birds and their health is of paramount concern. Within this region, 14 species of ticks have been documented, all of which may serve as vectors of mammal (including human) pathogens. By sampling birds at sites of varying levels of urbanization within the coastal southeastern urban matrix, I studied the relationship between ticks and their avian hosts, and how this relationship varies seasonally. Mistnets were set-up at five permanent sites …

First Nesting Record And Status Review Of The Glossy Ibis In Nebraska, Joel G. Jorgensen, W. Ross Silcock

Nebraska Bird Review

Glossy Ibis (Plegadis falcinellus) is believed to be a recent colonist from the Old World whose numbers have increased and range has expanded in North America over the past two centuries (Patten and Lasley 2000). Glossy Ibis range expansion has been described as involving periods of relative stability followed by periods of rapid increase (Patten and Lasley 2000). Prior to the 1980s, Glossy Ibis were primarily found in the southeastern United States and along the Atlantic Coast (Patten and Lasley 2000). In the mid to late 1980s, Glossy Ibis began to rapidly increase and expand into Texas. By …

This summer was very wet over most of the state. Breeding Bird Survey operators noted impassible roads, especially in the western Sandhills. The benefits to water birds in the Rainwater Basin were obvious, however, with notable breeding records for Ruddy Duck and White-faced Ibis, as well as the first documented breeding in the state of Glossy Ibis, and the first Rainwater Basin breeding for Double-crested Cormorant and third for Eared Grebe.

Additional notable breeding records were led by Osprey; after 7 years of trying at various locations, success came with a bang, as at least 3 nests successfully fledged young, …

Wintering Bald Eagle Count Trends In The Conterminous United States, 1986-2010, Wade L. Eakle, Laura Bond, Mark R. Fuller, Richard A. Fischer, Karen Steenhof

Biomedical Research Institute Publications and Presentations

We analyzed counts from the annual Midwinter Bald Eagle Survey to examine state, regional, and national trends in counts of wintering Bald Eagles (Haliaeetus leucocephalus) within the conterminous 48 United States from 1986 to 2010. Using hierarchical mixed model methods, we report trends in counts from 11 729 surveys along 844 routes in 44 states. Nationwide Bald Eagle counts increased 0.6% per yr over the 25-yr period, compared to an estimate of 1.9% per yr from 1986 to 2000. Trend estimates for Bald Eagles were significant (P ≤ 0.05) and positive in the northeastern and northwestern U.S. …

Buteo Nesting Ecology: Evaluating Nesting Of Swainson’S Hawks In The Northern Great Plains, Will M. Inselman, Shubham Datta, Jonathan Jenks, Kent Jensen, Troy Grovenburg

Natural Resource Management Faculty Publications

Swainson’s hawks (Buteo swainsoni) are long-distance migratory raptors that nest primarily in isolated trees located in areas of high grassland density. In recent years, anthropogenic conversion of grassland habitat has raised concerns about the status of the breeding population in the northern Great Plains. In 2013, we initiated a study to investigate the influence of extrinsic factors influencing Swainson’s hawk nesting ecology in north-central South Dakota and south-central North Dakota. Using ground and aerial surveys, we located and monitored nesting Swainson’s hawk pairs: 73 in 2013 and 120 in 2014. We documented 98 successful breeding attempts that fledged …
