The bears are more interested in chowing down on early-arriving red elderberries.

The research was conducted by biologists at Oregon State University, University of Montana’s Flathead Lake Biological Station, and Kodiak National Wildlife Refuge.
The findings were published this week in the journal Proceedings of the National Academy of Sciences.
