Predator species identification is an important step in understanding predator-prey interactions, but predator identifications using kill site observations are often unreliable. The authors used molecular tools to analyse predator saliva, scat and hair from caribou calf kills in Newfoundland, Canada to identify the predator species, individual and sex. The authors sampled DNA from 32 carcasses using cotton swabs to collect predator saliva.
