The use of alarm stimuli as a means of bird damage control is discussed. Effectiveness is dependent upon a number of factors, including environment, bird vulnerability to attack, time-of-day, physiological requirements, and the bird species’ social structure. Some species of birds respond well to alarm sounds, while others do not. Further experimen...

A historical review of predatory animal damage and the development of the Texas animal damage control (ADC) program is provided, including a discussion of predator species, methods of control and limitations caused by laws, regulations and policies. Recommendations are made for improvements to permit a more comprehensive program with adequate fundi...
A field study of unpadded and padded foothold coyote traps was undertaken in six western states in 1986-1987. Tests were designed to determine the capture efficiency and extent of foot injury caused by different trap modifications. Results were similar to an earlier study undertaken in 1984-85 that showed padded traps reduced foot injury but captur...
Although not a new idea, using aircraft to control blackbird damage to sunflowers has provided some relief for sunflower growers in North Dakota. The numerous scaring devices and limited frightening agents have not proven effective in controlling blackbird damage to sunflowers. In response to a congressional directive to provide assistance in contr...

From June 1976 through June 1989, 37 nonconsecutive patients underwent uterine curettage during the course of their gestational trophoblastic disease. In 22 patients (59%) trophoblastic tissue was obtained. Three (8.1%) patients sustained a uterine perforation during the procedure. In six patients curettage was performed for bleeding. There were si...
