Book excerpt: Reproductive Success of Nesting Terns and Black Skimmers on the Central Texas Coast (October, 2013). Rachel R. Fern, B.S., Texas State University M.S., Texas A&M University-Corpus Christi Chair of Advisory Committee: Dr. Kim Withers Seabirds are top predators at sea and are particularly sensitive to changes in the marine environment. This gives them significant potential as bioindicators of the current state of and shifts in marine ecosystems. Nest site selection is important because the demands of reproduction can be substantial and the reproducing pair is often confined to the area selected for the duration of the breeding season. Location of the nest in relation to vegetative cover, colony density and richness can strongly influence reproductive success via exposure to predators or weather events and competition for food resources and optimal nest sites. Additionally, the timing of nesting in the breeding season can influence the outcome of the breeding effort due to storm events and increasing ambient temperatures. This study defines temporal effects and correlations between reproductive success of nesting terns and skimmers and environmental characteristics of the nest site: area (ha), vegetative coverage, Spartina spp. coverage, elevation, nest density, assemblage richness and human disturbance. The four species included in this research (Forster's Tern Sterna forsteri, Gull-billed Tern Gelochelidon nilotica, Least Tern Sternula antillarum and Black Skimmer Rhynchops niger) were monitored at various nesting sites during the 2012 and 2013 breeding seasons. Reproductive success of Forster's Terns seemed to be influenced by human disturbance, nest density and species richness of the nest site. Elevation and Spartina spp. coverage both positively influenced the success of Least Terns. The nesting success of Gull-billed Terns was positively correlated with elevation and species richness of the nest site, and success of Black Skimmers was negatively correlated with species richness and positively correlated with elevation. All species that nested early in the breeding season suffered nest failure due to storm events; however, Gull-billed Terns were only marginally impacted. Establishing these correlations in environmental nest site characteristics and reproductive success of nesting terns and skimmers provides a baseline understanding of tern and skimmer breeding biology in the central Coastal Bend region of Texas, which may assist future management decisions and restoration efforts.

Download or read book Breeding Biology and Relation of Pollutants to Black Skimmers and Gull billed Terns in South Carolina written by Lawrence J. Blus and published by . This book was released on 1980 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The breeding biology and relation of pollutants to black skimmers and gull-billed terns were investigated in South Carolina from 1969 through 1975. With few exceptions, the two species nested together in colonies located on barrier islands. Both species nested in areas subject to tidal flooding, and the two species persisted in nesting in several colonies despite intense predation by rats and gulls. Estimated reproductive success varied greatly from year to year and colony to colony; success in most colonies seemed low, particularly for the gull-billed terns.

Available in PDF, EPUB and Kindle. Book excerpt: The Gulf of Mexico is one of the most important ecological regions in the world for birds. The mosaic of diverse habitats in the region provides numerous niches for birds. There are productive salt marshes, barrier islands, and sandy beaches for foraging and nesting; a direct pathway between North and Central and South America for migrating; and warm, tropical waters for wintering. Many species are residents all year around, some migrate through, and still others spend the winter along the shores. The Gulf Coast is home to a significant portion of the world’s population of Reddish Egret and Snowy Plover and a significant portion of the US breeding populations of certain birds, including the Sandwich Tern, Black Skimmer, and Laughing Gull. In total, there are more than 400 bird species that rely on the Gulf at some time during the year. Drawing on decades of fieldwork and data research, renowned ornithologist and behavioral ecologist Joanna Burger provides detailed descriptions of birdlife in the Gulf of Mexico. Burger records trends in bird population, behavior, and major threats and stressors affecting birds in the region, including the effects of the Deepwater Horizon oil spill in 2010. While some of this data exists in journal articles, research papers, and government reports, this is the first volume to weave together a comprehensive overview of the birds and related natural resources found in the Gulf of Mexico. Illustrated with over 900 color photographs, charts, and maps, this landmark reference volume will be immensely important for researchers, conservationists, land managers, birders, and wildlife lovers.
Download or read book Birdlife of Houston Galveston and the Upper Texas Coast written by Ted Eubanks and published by Texas A&M University Press. This book was released on 2006 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last thirty years, the Upper Texas Coast has become a "must go" destination for birders around the globe. This book will serve as an essential companion to the customary field guide and pair of binoculars for all visitors to Houston, High Island, Galveston, Freeport, or any of the area's other exciting birding spots. It also places the birdlife of the region, a seven-county area with a larger bird list than forty-three states, into historical and ecological contexts. Authors Eubanks, Behrstock, and Weeks--all recognized authorities on the migrant and resident birds of this region--present a thorough introduction to the area's history, physiography, and avifauna. Then, in generous discussions of bird families and species, they synthesize years of records, tracking the comings and goings of more than 480 birds and incorporating their own lifetimes of experience to create an "ornithological mosaic" of lasting significance.
