Evaluation of northern bobwhite in western Oklahoma
August 2011 - July 2017
- Oklahoma Department of Wildlife Conservation
Northern bobwhite (Colinus virginianus) populations have experienced a general decline across most of their range over the last 40–50 years (Brennan 1991, Sauer et al. 2008). Over this time period, populations across their entire range have declined by an average rate of 3.0% per year (Sauer et al. 2008). In Oklahoma, quail populations also have experienced a long-term decline. Objectives are to determine the major factors driving long-term changes in Oklahoma bobwhite populations, particularly production and survival, relative to the interaction of fire and grazing, arthropod availability (particularly during nesting and brood-rearing), aerial and terrestrial predation, and aflotoxins and their effects on production and survival.
