The Effect Of Shade Tree Species On Bird Communities In Central Kenyan Coffee Farms, Deven Kammerichs-Berke Jan 2020

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 …


Nest Success In A Grassland Bird Community: Microsite Selection & A Case For Nest Height Manipulation, Matt Kneitel Jan 2020

Nest Success In A Grassland Bird Community: Microsite Selection & A Case For Nest Height Manipulation, Matt Kneitel

Masters Theses

Grassland birds are a sensitive community and populations around the country have been declining. They are susceptible to low nest success due to loss of habitat and the small, fragmented patches that remain are often subjected to elevated levels of nest predation. The American goldfinch (Spinus tristis), which uses grasslands for feeding and nesting, is understudied given its abundance, due in part to its late-season nesting habits, and selection of taller woody vegetation as nesting substrate, which is atypical for many grassland nesting birds. American goldfinches were incorporated in this study which included nest height manipulation of goldfinch …


Factors Affecting Nest Success Of Colonial Nesting Waterbirds In Southwest Louisiana, Karis A. Ritenour Jul 2019

Factors Affecting Nest Success Of Colonial Nesting Waterbirds In Southwest Louisiana, Karis A. Ritenour

LSU Master's Theses

As the coastline of Louisiana shifts with global climate change, subsidence, and accelerated sea level rise, important breeding islands for colonial nesting waterbirds are disappearing. In many recent studies flooding has been a leading cause of nest failure for a variety of species, especially those that nest on the ground. I examined the nest success of four species of colonial nesting waterbirds with various nesting strategies on Rabbit Island in southwestern Louisiana during 2017 and2018 by determining nest and fledging success. I monitored 855 nests, including 457 Brown Pelicans nests with an estimated hatch probability of 70%, 270 Forster’s Terns …

Wyoming’S Ucross Ranch: Its Birds, History, And Natural Environment, Jacqueline Lee Canterbury, Paul Johnsgard Feb 2019

Wyoming’S Ucross Ranch: Its Birds, History, And Natural Environment, Jacqueline Lee Canterbury, Paul Johnsgard

Zea E-Books Collection

This book profiles 60 of the most abundant, characteristic, and interesting birds that have been regularly reported from the Ucross Ranch and the adjacent Powder River Basin. The 20,000-acre Ucross Ranch lies on the western edge of the Powder River Basin of northeastern Wyoming. Ucross is a textbook example of the prairie grassland/ shrubland habitat type referred to as the sagebrush steppe, a landscape that is an icon of Wyoming’s vast open spaces. We focus especially on those species that occur year-round or are present as breeders during the summer months, and we place emphasis on a unique group of …


Relationships Among Biodiversity Dimensions Of Birds In Nebraska, Nadejda Mirochnitchenko Dec 2018

Relationships Among Biodiversity Dimensions Of Birds In Nebraska, Nadejda Mirochnitchenko

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

Biological diversity, or biodiversity, is a multi-dimensional concept that can be decomposed to measure information about taxonomic, phylogenetic, and functional variation within communities. Although the dimensions of biodiversity are interrelated, the assumption that measuring one dimension of diversity can inform about patterns in another dimension does not necessarily follow from theory or empirical study. The relationships among biodiversity dimensions is not well understood, nor how differences among dimensions could influence conservation decision making. Using the avian community as a study system, we explored the relationships of breadth metrics from the taxonomic, phylogenetic, and functional dimensions among each other and across …

Stable Isotopes Reveal Opportunistic Foraging In A Spatiotemporally Heterogeneous Environment: Bird Assemblages In Mangrove Forests, Christina Buelow, April Reside, Ronald Baker, Marcus Sheaves Nov 2018

Stable Isotopes Reveal Opportunistic Foraging In A Spatiotemporally Heterogeneous Environment: Bird Assemblages In Mangrove Forests, Christina Buelow, April Reside, Ronald Baker, Marcus Sheaves

University Faculty and Staff Publications

Environmental heterogeneity can foster opportunistic foraging by mobile species, resulting in generalized resource and habitat use. Determining species’ food web roles is important to fully understand how ecosystems function, and stable isotopes can provide insight into the foraging ecology of bird assemblages. We investigated flexibility of food choice in mangrove bird assemblages of northeast Australia by determining whether species’ carbon and nitrogen isotopic values corresponded to foraging group classification described in the literature, such as groups of species that are omnivorous or insectivorous. Subsequently, we evaluated foraging group isotopic niche size, overlap, degree of individual specialization, and the probable proportions …

Development Of An Avian Index Of Biological Integrity For Kentucky Wetlands, Kaitlyn Kelly Jan 2018

Development Of An Avian Index Of Biological Integrity For Kentucky Wetlands, Kaitlyn Kelly

Online Theses and Dissertations

Bird communities are frequently used as bioindicators to assess environmental conditions, including in wetland habitats. I developed an avian index of biological integrity (IBI) for wetlands of Kentucky as an intensive assessment method to supplement an existing rapid assessment method used in regulatory programs. Birds are useful indicators because they are sensitive to environmental changes, abundant in various landscapes, occupy higher trophic levels, and can be sampled in a cost-effective manner. Breeding bird point count data from 103 sites were used to calculate a set of 49 avian community metrics. Avian metrics were tested for correlation with independent landscape, hydrology …

The North American Geese: Their Biology And Behavior, Paul A. Johnsgard Jul 2016

The North American Geese: Their Biology And Behavior, Paul A. Johnsgard

Zea E-Books Collection

The eight currently recognized species of North American geese are part of a familiar group of birds collectively called waterfowl, all of which are smaller than swans and generally larger than ducks. They include the most popular of our aquatic gamebirds, with several million shot each year by sport hunters. Our two most abundant waterfowl, the Canada goose and snow goose, have populations collectively totaling about 15 million individuals. Like swans, the lifelong pairbonding of geese, their familial care, and prolonged social attachment to their offspring are legendary. Their seasonal migratory flights sometimes span thousands of miles, and the sight …


The North American Grouse: Their Biology And Behavior, Paul A. Johnsgard Jun 2016

The North American Grouse: Their Biology And Behavior, Paul A. Johnsgard

Zea E-Books Collection

The ten currently recognized species of grouse in North America have played an important role in America’s history, from the famous but ill-fated heath hen, a primary source of meat for the earliest New England immigrants, to the ruffed grouse, currently one of the most abundant and soughtafter upland game birds in more than 40 states and provinces. This book summarizes the ecology, reproductive biology, and social behavior of all ten of the extant North American grouse species. It also describes the current status of grouse populations, some of which are perilously close to extinction. The social behavior of grouse …

Linking Vital Rates Of Landbirds On A Tropical Island To Rainfall And Vegetation Greenness, James F. Saracco, Paul Radley, Peter Pyle, Erin Rowan, Ron Taylor, Lauren Helton Jan 2016

Linking Vital Rates Of Landbirds On A Tropical Island To Rainfall And Vegetation Greenness, James F. Saracco, Paul Radley, Peter Pyle, Erin Rowan, Ron Taylor, Lauren Helton

Research outputs 2014 to 2021

Remote tropical oceanic islands are of high conservation priority, and they are exemplified by range-restricted species with small global populations. Spatial and temporal patterns in rainfall and plant productivity may be important in driving dynamics of these species. Yet, little is known about environmental influences on population dynamics for most islands and species. Here we leveraged avian capture-recapture, rainfall, and remote-sensed habitat data (enhanced vegetation index [EVI]) to assess relationships between rainfall, vegetation greenness, and demographic rates (productivity, adult apparent survival) of three native bird species on Saipan, Northern Mariana Islands: rufous fantail (Rhipidura rufifrons), bridled white-eye (Zosterops conspicillatus), and …

Breeding Birds Of Virginia, Bryan D. Watts Oct 2015

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 …


The Effects Of Urbanization On Tick Parasitism Rates In Birds Of Southeastern Virginia, Erin Leigh Heller Oct 2015

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 …
