I radio collared and monitored 90 bobwhites on 15 privately-owned fields in Searcy County in 2008 and 2009. Twenty nests were located and nest success was compared between nests located in hayfields and non-hayfields. Vegetation was compared between nest sites and reference locations to characterize nesting habitat. Vegetation and invertebrate abundance were compared between sites in which broods foraged and reference sites in order to characterize brood-rearing habitat. Finally, I compared thermal characteristics between sites in which bobwhites foraged and reference sites. I intended to assess the ability of bobwhite restoration lands to supply nesting and brood-rearing habitat. I developed models which described nesting and brood-rearing habitat and used this model to classify vegetation samples from restoration areas as either one of the two habitat types or as unsuitable for either activity. A discriminant function used to discriminate between nest sites, foraging sites and unusable habitat correctly classified 68% of foraging sites, 75% of nest sites, 50% of transit sites, and 12% of reference sites. Sixty-five percent of restoration area samples were classified as foraging sites, 10% as nest sites and 25% as unusable. Although the discriminant function identified foraging and nesting habitat on restoration areas, bobwhite seldom used any of the restoration areas during the breeding season. Thus, restoration efforts appear to be ineffective in providing suitable habitat for breeding bobwhites. Low invertebrate biomass and abundance on restoration areas may play a role in lack of use by bobwhite. In restoration areas, habitat similar to nesting habitat was produced 2-4 years after burning of disking. Breeding habitat for bobwhites should contain both nesting and foraging habitat. Thus, management practices should provide both nesting and foraging habitat, with a majority of foraging habitat. As many of the fields that were heavily used by bobwhite were lightly to moderately grazed, I conclude that grazing at that level may be an appropriate management tool for bobwhite.

The northern bobwhite (Colinus virginianus) is one of the most popular upland games species in North America, and in turn has been a focus of game management and research from as early as the 1920s. However, bobwhite populations continue to decline throughout their geographic range. The cumulative effects of advanced succession and monoculture farming are often cited as a primary cause of range wide declines. As productivity may be one of the most important factors associated with changes in population size, identifying and managing quality nesting and brood habitats is vital to reversing the steady downward trend in bobwhite populations. In 2003 and 2004, we compared nest success and brood habitat selection of radiotagged bobwhite between a managed and unmanaged (private) landscape in southeastern Iowa. Using program MARK, we estimated daily nest survival with the best approximating model that included an area and year effect only. The daily survival rate in 2003 was higher within the managed area (managed: 1.00, SE = 0.00; private: 0.953, SE = 0.023), whereas 2004 daily survival rates were similar between sites (managed: 0.969, SE = 0.011; private: 0.964, SE = 0.011). Microhabitat characteristics, landscape composition and configuration within 210 m of a nest, and applied management techniques did not have a measurable effect on nest success. At both the home range and patch scale, broods on the managed and private study areas used habitat types differently. At the home range scale, broods on the private area simply selected for all habitat types not in row crop production, while broods on the managed area selected for habitats with early successional habitat characteristics and showed an avoidance of timber patches. At the patch scale, broods 2-weeks of age on the managed area selected for early successional habitats. At 4 weeks of age, broods showed only an avoidance of timber patches. There was no statistical evidence for brood habitat selection at the patch scale on the private study area. The percent of forb canopy cover within a habitat patch was a significant predictor of brood use, as were fields burned the previous year.
