Texas Quails presents the first complete assessment of the four species of quail found in this vast state. Experts describe each of them and examine all geographic regions of the state for historical and current population trends, habitat status, and research needs. These experts also discuss management practices, hunting issues, economics, and diseases.

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.

Based on long-term roadside call counts performed by Texas Parks and Wildlife, scaled quail numbers have been declining since the mid to late 1980's in the Rolling Plains and SHP of Texas. Rollins (2000) reported that northwest Texas as well as the Oklahoma panhandle have only "relic populations" since the early 1990's, meaning current scaled quail distributions are smaller and more fragmented than before. However, the Trans-Pecos and Edwards Plateau ecoregions have the greatest abundance of scaled quail according to 15-yr data trends in the TPWD Forecast. Although there is a considerable amount of literature on this species, much of their ecology, specifically nesting and brood ecology, is not well understood (Silvy et al. 2007). Scaled quail survival rates have been estimated to be between 15-70%, depending on the study region.

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.
