Nocturnal Roost Tree, Roost Site And Landscape Characteristics Of Carnaby's Black-Cockatoo (Calyptorynchus Latirostris) On The Swan Coastal Plain, Candice Le Roux

Theses: Doctorates and Masters

There is limited information on communal roosting in parrot species of Western Australia and other parts of the world. Carnaby’s Black-Cockatoo is an endangered species that forms large nocturnal communal roosts, and for this reason they are an ideal model species to test the characteristics or factors that are associated with roost sites. Known roost sites distributed across the Swan Coastal Plain were identified and selected through the Great Cocky Count project. A minimum of five and maximum of ten individual trees were assessed at 11 roost sites with an overall total of 95 roost trees sampled. I determined the …

The Breeding Bird Community Of A Remnant Urban Woodland In Mcallen, Texas, John S. Brush, Alexis Racelis, Timothy Brush

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

We conducted a breeding bird survey of a remnant thorn-forest at McAllen Nature Center in 2015 and 2016 to assess the breeding bird community and compare it to that of a larger, exurban refuge. We recorded 37 territorial species in McAllen Nature Center, including 15 species not reported at the exurban tract. Thirteen of these predominantly used the more open, human -maintained habitats in the northern and western sides of the park. The presence of many common thorn-forest birds, including a subset of the regions “South Texas specialty” species, is encouraging. Small remnant woodlands such as McAllen Nature Center may …

Habitat Use By Wintering Passerines In Fire-Managed Forests Along The U.S. Gulf Coast, Justin Michael Michaud

Online Theses and Dissertations

Coastal habitats are being impacted by land development, fragmentation, and disturbance related to climate change. The remaining natural areas need to use planned management that may, in some cases, include the use of prescribed fire to maintain habitat quality. Numerous species of passerines, including some with declining populations, use the Gulf Coast as a wintering area, and some depend on habitats managed by fire. To provide information for land managers, I studied the winter bird community at Naval Live Oaks in Gulf Islands National Seashore with two primary objectives: (1) to describe the distribution, abundance, and diversity of the non-breeding …

Habitat Quality Modeling For Bird Species At Furman University, Emma Cook

Earth and Environmental Sciences Presentations

In rapidly urbanizing areas, such as Greenville County in Upstate South Carolina, it is important to study habitat use and quality across land cover types in order to maximize conservation. Habitat fragmentation is a threat to many species of birds in areas with increasing development, especially those species that utilize larger forest patches for nesting and foraging. While land cover type and patch size are extremely important factors in determining habitat quality for birds, recent research has shown that the matrix of surrounding landscape proves to be very important as well. The landscape matrix, sometimes called landscape mosaic, considers the …

Stopover On Galapagos During Autumn Migration Of Bobolinks (Dolichonyx Oryzivorus), Noah G. Perlut, Rosalind Renfrew

Environmental Studies Faculty Publications

The Bobolink (Dolichonyx oryzivorus) is the only landbird species that is known to stop every year in Galapagos while migrating; however, its stopover ecology while on the islands is unknown. In October 2015, we searched for and captured Bobolinks in the highlands of San Cristóbal. We found Bobolinks in two fields, separated by 9.15 km, at ∼425 m elevation. Average daily counts of Bobolinks on these two fields were 3.2 ± 1.8 and 4.8 ± 2.3 individuals. We caught nine individuals; body mass and fat reserves varied from 22.5–40.0 g and no fat reserves to 50–100% reserves, respectively. …

Fall Field Report, August–November 2016, W. Ross Silcock

Nebraska Bird Review

As usual, there was quite a bit to chew over in the Fall Seasonal Report, although it was generally a pretty uneventful season, especially among waterfowl and shorebirds. The mild fall allowed some good counts to occur, such as the 20+ Surf Scoters, 465 meadowlarks in Garfield Co, and at least 11 White-winged Doves.

First State Records are hard to come by; amazing was an Anna's Hummingbird that showed up in the Manning Family's central Omaha yard. How many pass through the yards of non-birders undetected? Always a mind-boggling thought. A 3rd state record Costa's Hummingbird came to light from …

Distribution, Abundance, And Migration Timing Of Greater And Lesser Sandhill Cranes Wintering In The Sacramento–San Joaquin River Delta Region Of California, Gary L. Ivey, Bruce D. Dugger, Caroline P. Herziger, Michael L. Casazza, Joseph P. Fleskes

Proceedings of the North American Crane Workshop

The Sacramento-San Joaquin River Delta region of California (hereafter, Delta region) is an important wintering region for the Central Valley Population of greater sandhill cranes (Grus canadensis tabida) and lesser sandhill cranes (G. c. canadensis), but basic information about the ecology of these birds is lacking to design a biologically sound conservation strategy. During the winters of 2007-08 and 2008-09, we conducted roost counts, roadside surveys, aerial surveys, and tracked radio-marked birds to define the geographic area used by sandhill cranes in the Delta region, document migration chronology, and estimate subspecies-specific abundance. Radio-marked sandhill cranes arrived in our study area …

Foraging Patterns And Population Density Of The Buff-Bellied Hummingbird (Amazilia Yucatanensis) In Hidalgo County, Tx, Megan I. Villarreal

Theses and Dissertations

The objective of this investigation was to examine the foraging patterns and population density of the Buff-bellied Hummingbird (Amazilia yucatanensis ) in Hidalgo County, TX. Previous studies showed that hummingbirds use flowers displaying traditional bird pollination (ornithophilous) characteristics: reddish coloration, tubular corolla, and extended anthers. Observation sessions noted type and frequency of flowering species utilized for nectar, characteristics, and number of individuals seen in each area. Amazilia yucatanensis showed higher use of ornithophilous flowers. Significant results found: f-ratio 5.45 > p-value (0.05) 3.24. Two highly utilized species showed the expected 20–40% sucrose content expected in ornithophilous flowers. Population density per …

Barn Owls (Tyto Alba) Crossing The Road - Examining The Interplay Among Occupancy, Behavior, Habitat Selection, And Roadway Mortality In Southern Idaho, Tempe Regan

Boise State University Theses and Dissertations

Barn Owls (Tyto alba) are killed by vehicle collisions in greater numbers than any other North American bird of prey. Interstate-84 (I-84) in southern Idaho, USA has among the world’s highest known rates of Barn Owl-vehicle collisions. Little is known about Barn Owl occupancy in this region, so it is unclear if owls are killed in proportion to their abundance, or if they are equally abundant in segments with lower mortality and somehow escape collisions. Furthermore, studies of Barn Owl movements and behavior are limited. I was interested in understanding (1) factors that affect Barn Owl occupancy in …

Migration Ecology Of American Woodcock (Scolopax Minor), Joseph Daniel Moore

Graduate Theses and Dissertations

Improving the understanding of American woodcock (Scolopax minor) migration ecology has been identified as a priority information need for woodcock management. Developments in remote tracking technology and analytical techniques present an opportunity to gain insight into woodcock migratory connectivity and migration phenology and to evaluate the degree in which the current two-region (Eastern and Central) basis for woodcock management represents migratory movements. To analyze woodcock migration using band return records, I excluded observations that took place during the migratory period. Using this dataset, 17.9% of records showed crossover between management regions, higher than the < 5% crossover found in studies including non-migratory band returns. During autumn migration, woodcock from the Central Region largely migrated to destinations within the Central Region, whereas woodcock from the Eastern Region migrated to destinations across their wintering range, mixing with individuals from the Central Region. Between 2013 and 2016, I deployed 75 satellite transmitters on woodcock. I tracked the migration paths of 61 woodcock and documented 88 woodcock migrations. Average migration duration was longer during spring migration (53 days) than during autumn migration (31 days) because woodcock made a higher number of close-together migratory stopovers, not because woodcock stayed at individual stopovers longer during spring migration. Woodcock captured in the Central Management Region used 2 primary migrations routes: a Western Route and a Central Route. The Western Route ran north-south, connecting the breeding and wintering grounds of the Central Management Region. The hourglass-shaped Central Route connected an area on the wintering grounds reaching from Texas to Florida, to sites throughout northeastern North America. Woodcock following the Central Route funneled between the Appalachian Mountains and the Mississippi Alluvial Valley in western Tennessee during both autumn and spring migration. A higher than anticipated percentage (36%, n = 12) of marked woodcock captured in Texas and Louisiana and monitored during spring migration migrated to breeding-period sites in the Eastern Management Region, raising questions about the biological basis of managing woodcock as separate populations. The supplementary material includes woodcock capture information (Appendix I), information on individual stopovers (Appendix II), and migration maps for individual woodcock (Appendix III).

Statistical Learning In Songbirds: From Self-Tutoring To Song Culture, Olga Fehér, Iva Ljubičić, Kenta Suzuki, Kazuo Okanoya, Ofer Tchernichovski

Publications and Research

At the onset of vocal development, both songbirds and humans produce variable vocal babbling with broadly distributed acoustic features. Over development, these vocalizations differentiate into the well-defined, categorical signals that characterize adult vocal behaviour. A broadly distributed signal is ideal for vocal exploration, that is, for matching vocal production to the statistics of the sensory input. The developmental transition to categorical signals is a gradual process during which the vocal output becomes differentiated and stable. But does it require categorical input?We trained juvenile zebra finches with playbacks of their own developing song, produced just a few moments earlier, updated continuously …
