Blood Parasites Infecting The Hoatzin (Opisthocomus Hoazin), A Unique Neotropical Folivorous Bird, M. Andreína Pacheco, M. Alexandra García-Amado, Jaime Manzano, Nubia E. Matta, Ananias A. Escalante

Harold W. Manter Laboratory of Parasitology: Library Materials

The Hoatzin (Opisthocomus hoazin) is the only extant member of the order Opisthocomiformes. This unique South American bird lives in the riparian lowland vegetation characteristic of the Amazon and Orinoco basins. Hoatzins nest in communal social units close to water bodies; they are strictly folivores being the only bird with pregastric fermentation in the crop. Because of the complex logistics involved in capturing this bird, there is a knowledge gap on its parasites. This study documents two distant lineages of haemosporidian parasites (Plasmodium spp.) in a juvenile and two adults sampled in the Cojedes state, Venezuela. Although …

Winter Field Report, December 2018 To February 2019, W. Ross Silcock

Nebraska Bird Review

As has been the trend in recent winters, and despite the relative coolness of this winter, there were numerous examples of species north of expected midwinter ranges or present in higher numbers than usual in winter. The long list includes unexpected midwinter records of Tundra Swan, American Wigeon, Ring-necked Duck, Lesser Scaup, White-winged Dove, Sandhill Crane, Clark’s Grebe, Doublecrested Cormorant, Red-shouldered Hawk, and Yellow-bellied Sapsucker. Startling was the state’s first winter record of Sedge Wren, perhaps the biggest rarity of the season. And Eastern Meadowlark was documented in midwinter for the first time, although its presence in the southeast has …

Weak Effects Of Geolocators On Small Birds: A Meta-Analysis Controlled For Phylogeny And Publication Bias, Vojtěch Brlík, Noah G. Perlut

Environmental Studies Faculty Publications

Currently, the deployment of tracking devices is one of the most frequently used approaches to study movement ecology of birds. Recent miniaturization of light-level geolocators enabled studying small bird species whose migratory patterns were widely unknown. However, geolocators may reduce vital rates in tagged birds and may bias obtained movement data. There is a need for a thorough assessment of the potential tag effects on small birds, as previous meta-analyses did not evaluate unpublished data and impact of multiple life-history traits, focused mainly on large species and the number of published studies tagging small birds has increased substantially. We quantitatively …

This specimen, housed in the University of New England ornithological collection, is the latest documented fall record of this species in North America.

The Isolation Of Presumptive Pathogens From The Pellets Of Seven North American Owl Species, Quoc Nguyen

Merge

Most birds, especially raptors such as owls (Strigiformes), egest pellets, which are regurgitated masses of the owl’s prey. The contents of the pellets may contain hair, teeth, and bones which are usually indigestible since an owl’s stomach lacks the necessary ability to break down the ingested material. Furthermore, the formed pellets cannot pass through the digestive tract and are regurgitated since it would either be too dangerous to pass through the digestive system or would block additional ingestion of new food, hence the reason to egest the pellets. Research on the pathogenic bacteria in owl pellets are scant but understanding …

Anthropogenic Influence On Falco Sparverius Populations Within Washington State, Jesse Squibb

Undergraduate Honors Theses

American Kestrel (Falco sparverius) populations have been fluctuating throughout the United States. A primary focus in studying these birds has been on the decline of the small raptor along the East Coast of the United States. This project focuses on the American Kestrel populations within Washington State between 2005 and 2011. The goal of this project was to determine whether or not the trend in Washington are similar to those along the East Coast. This study uses data from Global Biodiversity Information Facility, Christmas Bird Count, and North American Breeding Bird Survey for American Kestrel Sightings. The United …

Cerulean Warbler (Setophaga Cerulea) And Associated Species Response To Operational Silviculture In The Central Appalachian Region, Gretchen Emily Nareff

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this study, I assessed the response of Cerulean Warblers (Setophaga cerulea) and 5 additional songbird species to timber harvests prescribed through operational silviculture. The research took place in relatively contiguous mature deciduous forests in 4 states in the central Appalachian region—Kentucky, Pennsylvania, Virginia, and West Virginia, USA.

For the first part of the study, I collected Cerulean Warbler abundance and territory data through point counts and territory mapping, respectively. I used the point count data to model Cerulean Warbler abundance pre- and post-harvest at 5 study areas (Kentucky [n=1], Virginia [n=2], West Virginia [n=2]) and post-harvest at …

History And Current Status Of The Inca Dove (Columbina Inca) In Arkansas, Ragupathy Kannan, Jack Jackson, Ethan Brooks

Journal of the Arkansas Academy of Science

Formerly a bird of Central America, Mexico, and the southwestern United States, the Inca Dove (Columbina inca) has been expanding northward across North America in the past few decades. It first appeared in Arkansas on October 26, 1968 in Saratoga, Howard County. Since then, the statewide range has grown to include at least 36 of 75 counties and is expanding. With the use of Christmas Bird Counts, Breeding Bird Surveys, and two citizen science sources, eBird and AR-Birds, we compiled 368 records of the species in the state. Inca Doves were observed year-round in Arkansas and are expanding …

Greater Sage-Grouse Survival, Breeding Ecology, Resource Selection, And West Nile Virus Prevalence On The Eastern Fringe Of Their Range, Lindsey Anne Parsons

Electronic Theses and Dissertations

The greater sage-grouse (Centrocercus urophasianus) is a sagebrush (Artemisia spp.) obligate species that has experienced population declines over the past several decades. Sage-grouse are a species of conservation concern throughout the Intermountain West and are considered a species of greatest conservation need in South Dakota. Numerous studies have documented drivers of demographic performance at the core of their distribution; however, relatively few studies have examined sage-grouse inhabiting the eastern extent of their range, in South Dakota. We sought to examine sage-grouse space use in multiple seasons, estimate survival, and determine factors affecting nest success in South Dakota …

Identifying An Optimal Bald Eagle Monitoring Program For Southwest Alaska National Parks, Rebecca Kolstrom

Electronic Theses and Dissertations

The Southwest Alaska Inventory and Monitoring Network includes bald eagle monitoring as part of their Vital Signs Monitoring Plan. Lake Clark National Park and Preserve, Katmai National Park and Preserve, Kenai Fjords National Park, and Wrangell – St. Elias National Park and Preserve monitor bald eagles annually, albeit slightly differently among parks. Since monitoring decisions involve multiple objectives and stakeholders, there was a need for a structured approach to identify an optimal monitoring program. We used a structured decision making process and an iterative, four-round Delphi Process to collect information about long-term bald eagle monitoring from experts. We collected information …

Factors Influencing Parental Care And Home Range Size Of A Monomorphic Species, The Red-Headed Woodpecker (Melanerpes Erythrocephalus), L. Abigail Walter

Theses and Dissertations

Parental care in animals can be costly and is shared between both parents in many bird species. Not surprisingly, most studies of how parental care is shared between the sexes are in sexually dimorphic species, and much less in known about sexually monomorphic species where sex cannot be determined in the field. This has prevented a full understanding of parental care behaviors – which are intrinsically linked to fitness – in species such as the Red-headed Woodpecker (Melanerpes erythrocephalus) that is experiencing population declines throughout much of its range. In this study we assessed whether Redheaded Woodpecker brooding time, nestling …

Capsaicin As A Tool For Repelling Southern Flying Squirrels From Red-Cockaded Woodpecker Cavities, Robert T. Meyer, James A. Cox

Human–Wildlife Interactions

The southern flying squirrel (Glaucomys volans) is an important kleptoparasite of cavities excavated by the imperiled red-cockaded woodpecker (Dryobates borealis). Flying squirrel usurpation of cavities may affect woodpecker productivity, but current efforts to manage flying squirrels are costly and time consuming. We assessed whether capsaicin could deter flying squirrel use of woodpecker cavities on a site in southwest Georgia, USA. Twenty-nine cavity tree clusters received 4 treatments: capsaicin, water, air, and a control (no treatment). Only capsaicin both removed more flying squirrels from the cavity immediately after its application and decreased the probability of a flying …

European Starlings Fly Before They Fledge, Jeremiah L. Psiropoulos, Lisa A. Selner

Human–Wildlife Interactions

Aircraft bird strikes are increasing globally. Bird strikes constitute a major human health and safety risk and result in millions of dollars in economic impacts. Invasive avian species, such as the European starling (Sturnus vulgaris; starlings), have been implicated in bird strikes in North America. Because this species is highly adaptive and has been successful at establishing in new areas, such as airports, it is essential that managers better understand the potential risks and how to mitigate them. Herein we present a case study regarding a novel observation of unique starling nesting behavior that may pose a risk …

Tracking Canada Geese Near Airports: Using Spatial Data To Better Inform Management, Ryan J. Askren, Brett E. Dorak, Heath M. Hagy, Michael W. Eiccholz, Brian E. Washburn, Michael P. Ward

Human–Wildlife Interactions

The adaptation of birds to urban environments has created direct hazards to air transportation with the potential for catastrophic incidents. Bird–aircraft collisions involving Canada geese (Branta canadensis; goose) pose greater risks to aircraft than many bird species due to their size and flocking behavior. However, information on factors driving movements of geese near airports and within aircraft arrival/departure areas for application to management are limited. To address this need, we deployed 31 neck collar-mounted global positioning system transmitters on Canada geese near Midway International Airport in Chicago, Illinois, USA during November 2015 to February 2016. We used the …

Comparison Of Conservation Policy Benefits For An Umbrella And Related Sagebrush-Obligate Species, Jonathan B. Dinkins, Jeffrey L. Beck

Human–Wildlife Interactions

Many conservation strategies promote the potential of multiple species benefitting from protection of large areas necessary for the continued viability of 1 species. One prominent strategy in western North America is Wyoming’s Sage-grouse Core Area Policy, which was designed to conserve greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) breeding habitat, but may also serve as an umbrella to conserve other sagebrush (Artemisia spp.)-obligate wildlife, including songbirds. Sagebrush-obligate songbirds and sage-grouse have undergone population declines throughout the western United States attributed to similar habitat issues. We compared trends of sagebrush-obligate songbirds from the Breeding Bird Survey and sage-grouse lek …
