Depredation On Artificial Ground Nests By Japanese Macaques: The Unspoken Exotic In Texas, Justin G. Feild, Scott E. Henke, Justin G. Mccoy
Great Plains Wildlife Damage Control Workshop Proceedings
Japanese macaques (Macaca fuscata) are old world monkeys that were introduced to Texas in 1972, and their population has since increased to over 800 individuals. Macaques are considered to be primarily vegetarian but will opportunistically forage on a variety of food items. Therefore, the objective of this study was to determine if macaques impact the nest success of bobwhite quail (Colinus virginianus). In June 1996, 20 artificial ground nests simulating those of bobwhite quail were placed randomly in areas with and without macaques. Nests were checked at 3-day intervals for 24 days and nest success was …

Lesser Scaup Depredation And Economic Impact At Baitfish Facilities In Arkansas, M. Chad Philipp, Michael D. Hoy
Great Plains Wildlife Damage Control Workshop Proceedings
During the winters of 1994-95 and 1995-96, unusually large numbers of diving ducks were observed on baitfish facilities in Arkansas. Historically, lesser scaup (Aythya affinis) inhabited baitfish ponds with little reported impact on minnow production, and thus little attention was paid to the birds. Unfortunately, minnow crops in the spring of 1995 fell short of expectations and immediate attention became focused on the role lesser scaup may have had on that minnow shortage. Subsequently, lesser scaup were collected from baitfish facilities in an effort to determine their effect on commercial fish farms. Two hundred and twenty-three lesser scaup …
