Preliminary Analysis Of The Effects Of Non-Target Supplemental Feeding On Camera Trap Captures Of Small Mammals In Central Georgia, Raena Mccown, Travis Cunningham, Alfred J. Mead
Preliminary Analysis Of The Effects Of Non-Target Supplemental Feeding On Camera Trap Captures Of Small Mammals In Central Georgia, Raena Mccown, Travis Cunningham, Alfred J. Mead
Georgia Journal of Science
Supplemental bird feeding is a widespread hobby throughout western culture. Although it brings joy to many people, bird feeding has been shown to have potentially negative effects on local bird populations and small mammalian species. To study the differences in local occurrence of native small mammalian species around bird feeders and in more distant settings, six camera traps were placed in a rural residential area in Putnam County, Georgia. Three cameras were placed facing bird feeders and three placed a minimum of 60 m away from the feeders. Species presence was recorded three days a week from 12:00 am Monday …

Human–Wildlife Interactions
Annually, in the United States, >1 million deer (Odocoileus spp.)–vehicle collisions are reported, resulting in losses of $4.6 billion in vehicle damage and medical expenses. Wildlife and transportation managers require better information about traffic volumes relative to seasonal and diurnal deer movement patterns to appropriately evaluate the risks associated with deer–vehicle collisions (DVCs). We incorporated traffic volume data with DVC data and the movement rates and incidences of road crossings by white-tailed deer (O. virginianus) to evaluate if traffic volume or deer behaviors mediate the incidence of DVCs along a high-volume interstate highway in Morgan County in …

Partial clutch loss following a predation event is rarely studied in ground-nesting birds despite predation often being the leading cause of nest failure. Partial nest depredation occurs when predators attack but leave some eggs intact. Using continuous video monitoring, we documented a total of 372 initial predation events at nests of Northern Bobwhites (Colinus virginianus). From these, we observed a sample of partial nest pre-dation events (n=47). Partial predation events resulted in three outcomes: (1) The nest failed due to parental abandonment; (2) adult stayed with the nest, but clutch failed to hatch, usually due to further predation events; or …

Infectious Bursal Disease In Wild Populations Of Turkeys And Sandhill Cranes: Preliminary Findings, Kristen L. Candelora, Marilyn G. Spalding, Stephen A. Nesbitt, Holly S. Sellers, Jeremy Olson, Larry Perrin, Jeannette Parker
Proceedings of the North American Crane Workshop
Captive-reared whooping cranes (Grus americana) released into Florida for the resident reintroduction project experienced unusually high mortality and morbidity during the 1997-1998 and 2001-2002 release seasons (Spalding et al. 2008). Infectious bursal disease virus (IBDV) serotype 2 is currently under investigation as the factor that precipitated the mortality events. A small percentage of whooping cranes have been exposed to IBDV in the captive setting. However, many more are being exposed postrelease, and prevalence of exposure seems to increase with age or length of time the birds are in the wild in Florida (Spalding et al. 2008). The goals …
Translocation Of Florida Sandhill Cranes To Georgia, Wesley A. Abler, Stephen A. Nesbitt
Translocation Of Florida Sandhill Cranes To Georgia, Wesley A. Abler, Stephen A. Nesbitt
Proceedings of the North American Crane Workshop
Wild Florida sandhill cranes (Grus canadensis pratensis) were captured in Florida during 3 years and translocated to Grand Bay Wildlife Management Area (GBWMA), Georgia, in an attempt to establish a resident population of Florida sandhill cranes in a location with suitable habitat but no known population of resident sandhill cranes. Translocated second-year subadult cranes commingled with migratory greater sandhill cranes (G. c. tabida) yet remained on GBWMA each year after the migratory birds left the area. Twenty-one of 35 released cranes were visually identified at least 5 months after release, 3 cranes more than 15 months …
Food And Feeding Habits Of Released Florida Sandhill Cranes, Christine R. Rucker
Food And Feeding Habits Of Released Florida Sandhill Cranes, Christine R. Rucker
Proceedings of the North American Crane Workshop
Food habits of 4 pairs of free-ranging Florida sandhill cranes (Grus canadensis pratensis) on St. Catherine's Island, Georgia, were studied from May to October 1990. Food items were identified and quantified at close range « 10 m). The 4 pairs varied in how they used plant and animal resources (P < 0.0001). Animal material in the diets averaged 19.1 % and ranged from 13.4 to 36.7%. Plant material averaged 80.9% in the pairs' diets. Major foods included subsurface bulbs, roots, and tubers of yellow star grass (Hypoxis micrantha), catbrier (Smilax glauca), and false garlic (Allium bivalva), longleaf pine seeds (Pinus palustris), and insects. Food habits shifted seasonally for all pairs (P < 0.(001). In July and August the percent occurrences of yellow star grass and false garlic in the diets were > 50 %. During September and October pine seed occurrence was > 75 % in the diets of …
