Thought that some of you guys would find this somewhat enlightening.
“Brown bear wakes up from hibernation and kills 38 reindeer calves”
Why are some bears more predatory? "It must be a combination of different factors," study co-author Antonio Uzal Fernandez, a senior lecturer in wildlife conservation at Nottingham Trent University in the U.K., told Live Science in an email, "such as innate behaviour related to personality (for instance, some people are more aggressive than others)."
Ummm...maybe the factor that determines which bears are more predatory is simply that they actually tracked the killings by a particular bear. Methinks most bears kill and eat everything they can find...
