AN INEXPENSIVE AND AUTOMATIC MULTIPLE-EXPOSURE PHOTOGRAPHIC SYSTEM

This paper describes the design, construction and deployment of a simp le automatic camera system that was used to document the identities of scavengers on the carcasses of migratory fishes. The camera system fu nctioned properly in adverse weather during extended deployment, and r ecorded a wide range of terrestrial vertebrate species under natural c onditions. Bird species recorded by the device included Red-shouldered Hawk (Buteo lineatus), Common Crow (Corvus brachrhynchos). Turkey Vul ture (Cathartes aura), and Great Blue Heron (Ardea herodins). The inex pensive photographic system may have wider application to other studie s of bird behavior and distribution.
