The declining bobwhite populations evident throughout the Southeast are cause for concern. Whereas habitat loss and/or intensified agriculture have been implicated as two potential causal mechanisms for these declines, few studies have directly compared bobwhite demographics between agricultural and managed bobwhite plantation landscapes. Therefore, we monitored northern bobwhite (Colinus virginianus; hereafter, bobwhite) via radiotransmitters (N = 472) on a center-pivot irrigated agricul-tural landscape (N = 154) and an adjacent, intensively-managed bobwhite plantation (N = 318)...

We estimated seasonal and annual survival and cause-specific mortality of northern bobwhite (Colinus virginianus) on an intensively managed plantation in Georgia. During 1992-1997, we radio-marked 813 bobwhite and determined causes and temporal patterns of mortality. Annual survival (0.201) did not differ between sexes and was higher than that reported for other populations throughout the Southeast. Yearly variation in annual survival was primarily associated with variation in overwinter mortality. Seasonal survival did not differ between sexes and mortality was equitably distributed...

Adult and immature wild swine (Sus scrota) were marked using freezebranding. Irons were applied for various durations to determine the most appropriate branding time. Light-colored skin and a permanent hair loss were produced by iron application times of 100 to 120 sec for adults and 20 to 24 sec for immature animals. Marks were permanent and readable up to 100 m.
