Book excerpt: Annual abundance of northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) fluctuates drastically in Texas, which complicates a quail manager's ability to forecast quail abundance for the ensuing hunting season. The Texas Quail Index (TQI) was a 5-year citizen-science project that evaluated several indices of quail abundance and habitat parameters as predictors of quail abundance during the ensuing fall. I found that spring cock-call counts explained 41% of the variation in fall covey-call counts for all study sites in year 1-4, and 89% of the variation in year 5. Further investigation revealed that year 5 was a drought year and had a significantly lower percentage of juveniles in the hunter's bag. These results suggest that during drought years, fall quail abundance is more predictable than during non-drought years and that low breeding success may be the reason. If these data are correct, quail managers should have a better ability to predict the declines of their fall quail abundance in the dry years. The TQI relied on citizen scientists (cooperators) to collect data. Since most (66.1%) cooperators dropped out of the program, and

Book Synopsis Comparative Ecology of Bobwhite and Scaled Quail in Southern Texas by : Marcia H. Wilson

Available in PDF, EPUB and Kindle. Book excerpt: 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 or read book Texas Bobwhites written by Jon A. Larson and published by University of Texas Press. This book was released on 2010-08-25 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This book presents the results and conclusions of the longest continuous study ever undertaken for a local North American game bird population. Since 1950 abundance has been determined seasonally by direct count, nesting ecology by field searches and observation, and hunting pressure and harvest by field interviews. Land use and weather conditions also have been recorded. The period of the study saw considerable change in regional land use and included several of the most severe winters in recorded weather history. Continuing harvest of the study population did not have a progressively depressing effect on standing densities; rather it held breeding stock somewhat below K at a more productive point on the growth curve. Roseberry and Klimstra report that there was clear evidence of an 8 to 10-year cycle within the study population. They found after examining a number of cycle theories that a close temporal relationship existed between their bobwhite data and the nodal lunar cycle described by Archibald (1977). Sound field techniques, long-term data acquisition, and appropriate mathematical and statistical treatment of the data combine to provide a significant contribution to what is known of not only bobwhite but basic population ecology.

Wilson and published by . This book was released on 2021 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
