I came across the following in an article about dove hunting:
...the study recorded the hits and misses of 5,094 shots with size 6 and 7 steel shot and 7 1/2 lead shot, killing a total of 1,146 doves, 1,100 of which were necropsied.
After looking this up it seems necropsy is another way of saying that an autopsy was performed; the body was examined after death.
When should we prefer one to the other?
