Waterbird Use of Brackish Wetlands Managed for Waterfowl

Waterbird use of managed and unmanaged brackish wetlands in coastal South Carolina was determined by 1,544 counts during a 19-month study. Significantly (P < 0.05) more individual birds and species used the managed sites in all seasons except summer. An unmanaged tidal impoundment was least used in all seasons. Multiple regression analysis indicated that bird use was inversely correlated to water level, particularly during spring. Shorebirds accounted for 53% of the use among managed sites follwed by waterfowl (27%), waders (14%) and other waterbirds (6%). The results have strong...


HomeRange and Mortality of White-Tailed Deer Fawns in Coastal South Carolina

During the summers of 1981 and 1982, 48 white-tailed deer (Odocoileus virginianus) fawns were captured and radio-collared on the Cat and South island portions of the Tom Yawkey Wildlife Center, Georgetown, South Carolina. Significantly (x2 = 4.10, P < 0.05) more male fawns were captured than females. Telemetry and visual locations (N = 731, range = 18 to 224) were taken on 11 fawns. All fawns utilized open inter-tidal marsh/marsh edge habitat. Home range and activity of individual fawns were highly variable. Mortality of radio collared fawns was 84.4% (38 of 45). Marking activities were...


Predation on White-tailed Deer Fawns by Bobcats, Foxes, and Alligators: Predator Assessment

Forty-eight white-tailed deer fawns (Odocoileus virginianus) were marked during the spring and early summer of 1981 and 1982. Forty-one (85.4%) of these fawns died, 26 (63%) due to predation. In 18 of the 26 predator-caused deaths, the species of predator could be determined. Bobcats (Felis rufus) accounted for 12 deaths, while red foxes (Vulpes vulpes) , gray foxes (Urocyon cinereoargenteus) and alligators (A lligator mississipptensis) were responsible for a total of at least 6 fawn deaths. Criteria for determining predator damage are discussed. Foxes and alligators have not previously...
