For my research goals I addressed the theoretical importance of competition in habitat selection of 2 quails and examined the use of resources in peripheral and core areas. Methodological objectives were to determine cover and food selection of Texas bobwhite (Colinus virginianus texanus) and chestnut-bellied scaled quail (Callipepla squamata castanogastris) in southern Texas. The Welder Refuge was the core area for bobwhites. The Chaparrosa and Experiment Ranches were peripheral areas for both quails. The core population for scaled quail was located at the Killam Ranch. Available cover formed a gradient from Welder to Killam. The highest percentage of herbaceous material was on Welder, whereas the largest amount of bare ground and shrub cover was at Killam. Bobwhites and scaled quail used and preferred different cover types. Bobwhites selected dense herbaceous material, whereas scaled quail preferred sparse vegetation and a shrub overstory. Based on niche breadth estimates, both quails used a narrow range of cover types in their respective core areas and a broad range in the peripheral areas. The frequency of available food items also formed a gradient. Welder had the largest percent frequency of animal matter and of herbaceous seeds and green leaves. Killam had the highest frequency of seeds, leaves, and fleshy fruits from woody plants. Bobwhites preferred grass seeds and animal matter, whereas scaled quail selected the fruits and seeds of woody plants. Niche breadth estimates were relatively constant for each quail. Theoretically, when intraspecific competition is most intense a species selects a broad range of habitats, whereas sympatric species occupy a narrow range of resources due to interspecific competition. However, when I used niche breadth estimates to address my first goal, neither component of the habitat (cover or food) followed the anticipated pattern. Therefore, I believe competition is not the major selective force in habitat selection of quails. The generalization has been put forth that in the peripheral part of a range birds occupy their optimal habitat, whereas at the center of the range, optimal and suboptimal habitats are used. However, the core area contains an abundance of preferred habitat and a species is able to meet its life-history requirements within a narrow range of cover types. Peripheral areas supply only suboptimal habitat and in order to fulfill the species-specific needs a species must use a wide range of cover types.

Download Texas Bobwhites Book in PDF, ePub and Kindle
Northern bobwhites are one of the most popular game birds in the United States. In Texas alone, nearly 100,000 hunters take to the field each fall and winter to pursue wild bobwhite quail. Texas is arguably the last remaining state with sufficient habitat to provide quail-hunting opportunities on a grand scale, and Texas ranchers with good bobwhite habitat often generate a greater proportion of their income from fees paid by quail hunters than from livestock production. Managing and expanding bobwhite habitat makes good sense economically, and it benefits the environment as well. The rangelands and woodlands of Texas that produce quail also support scores of other species of wildlife. Texas Bobwhites is a field guide to the seeds commonly eaten by northern bobwhites, as well as a handbook for conserving and improving northern bobwhite habitat. It provides identifying characteristics for the seeds of 91 species of grasses, forbs, woody plants, and succulents. Each seed description includes a close-up and a scale photo of the seed and the plant that produces it, along with a range map. Using this information, hunters can readily identify concentrations of plants that are most likely to attract quail. Landowners and rangeland managers will greatly benefit from the book's state-of-the-art guidance for habitat management and restoration, including improving habitat dominated by invasive and nonnative grasses.

Download The Upland and Webless Migratory Game Birds of Texas Book in PDF, ePub and Kindle
Authored by some of the state’s top wildlife scientists, The Upland and Webless Migratory Game Birds of Texas presents the most up-to-date and comprehensive information covering twenty-one species of game birds. Ranging from the most well-known, like the Wild Turkey and Mourning Dove, to the marsh-loving rails and other more elusive species, these birds have widespread appeal among both hunters and birders and underscore the diverse challenges facing wildlife scientists, land managers, and conservationists in Texas today. From cultural significance to taxonomy and evolutionary history, this volume provides a wealth of background information on these species. Additionally, the book offers illustrated species accounts, detailed range maps, and information about habitat and management requirements, hunting regulations, and research priorities. Readers will gain a deeper understanding of these game birds and the array of terrestrial and wetland landscapes key to their survival. This will serve as a convenient and thorough reference volume for wildlife biologists and enthusiasts, as well as landowners and hunters.
