Abstract
The objectives of this study were to monitor postmortem changes in the eyes of selected species, as well as other physical changes. In order to obtain a more suitable manuscript, people from other states were contacted . Their data, along with some published data, was included in this manuscript . We were, therefore, able to cover post-mortem changes in several species. For deer, data was collected on temperature, electrical stimulus, rigor mortis, pupil diameter, pictorial changes, and chemical changes in the potassium and glucose levels within the eye . Waterfowl data included temperatures, rigor mortis, physical changes in the eye, electrical stimulus and changes in potassium levels in the vitreous humor of the eye . I n pheasants, changes were primarily with temperature and physical and chemical changes in the eye . In pheasants, changes were primarily with temperature and physical and chemical changes in the eye . Cottontail rabbit data dealt with both temperature and electrical stimulus. Data on black bear, elk and raccoon dealt predominately with temperature . Much of the data (especially deer) was supplied by cooperative hunters, and the remainder predominately by wildlife biologists. Much of the data is presented in table s . Hopefully it is in a form usable by conservation officers and field biologists . Most of the information on time of death (TOD) requires an "on the spot" evaluation of existing data. This means that field personnel will most likely have to make the final decision on TOD .
