“…Fire ants depredate Northern Bobwhite (Colinus virginianus) nestlings and fledglings (Pedersen et al 1996;Mueller et al 1999). We captured one adult Black Rail with toes deformed on both feet in a manner consistent with fire ant stings (A. R. Forbes, pers.…”

“…These declines have occurred despite the economic importance of the northern bobwhite as a game species and extensive efforts to maintain and improve its population welfare. Hypotheses proposed to explain local or regional population declines include reduction in fledgling survival due to predation by imported fire ants (Allen et al 1995;Giuliano et al 1996;Mueller et al 1999;Pedersen et al 1996), loss and fragmentation of habitat (FenskeCrawford and Niemi 1997;Fleming and Giuliano 2001), extreme weather events such as drought and flooding (Guthery et al 2000;Hernandez et al 2005;Lusk et al 2001;Robel and Kemp 1997), and hunting pressure (Burger et al 1999;Guthery et al 2004a;Madison et al 2002;Peterson 2001). An exhaustive review of the dramatic range-wide population declines of bobwhites in the southeastern range of the species conducted by the Southeastern Quail Study Group concluded that habitat losses including qualitative changes (conversion of native warm season grasses to exotic cool season and warm season species) and quantitative habitat losses to urban expansion and transportation structures have been the most universally significant causes (Dimmick 1992).…”

Patterns of space and habitat use by northern bobwhites in South Florida, USA

The manner by which animals use space and select resources can have important management consequences. We studied patterns of habitat selection by northern bobwhites (Colinus virginianus) on Babcock-Webb Wildlife Management Area, Charlotte County, Florida and evaluated factors influencing the sizes of their home ranges. A total of 1,245 radio-tagged bobwhites were monitored for 19,467 radio days during 2002-2007. The mean (±1 SE) annual home range size, estimated using the Kernel density method, was 88.43 (±6.16) ha and did not differ between genders. Winter home ranges of bobwhites (69.27±4.92 ha) were generally larger than summer home ranges (53.90±4.93 ha). Annual and winter home ranges were smaller for bobwhites whose ranges contained food plots compared to those that did not; however, the presence of food plots did not influence summer home ranges. We used distance-based methods to investigate habitat selection by bobwhites at two scales: selection of home ranges within the study site (second-order selection) and selection of habitats within home ranges (third-order selection). Across both scales, bobwhites generally preferred food plots and dry prairie habitat and avoided wet prairies and roads. This pattern was generally consistent between genders and across years. Our data indicate that management practices aimed at increasing and maintaining a matrix of food plots and dry prairie habitat would provide the most favorable environment for bobwhites.

“…effects also are possible (Allen et a1., 1995;Guiliano et a!., 1996;Pedersen et a!., 1996). Indirect effects have been documented for juvenile northern bobwhite (Colinus virginianus), including lower survival rates and body mass gain (Giuliano et al, 1996) and behavioral changes including reduced time spent foraging and resting (Pedersen et a1., 1996).…”
