Here is an interesting perspective on food safety from BBC News:
“Selecting benign prey such as salmon makes sense from a safety point of view,” wrote Dr Chris Darimont, from the University of Victoria, BC, and his colleagues in the journal BMC Ecology. “While hunting deer, wolves commonly incur serious and often fatal injuries,” the researchers said, adding that salmon fishing is much less time consuming than tracking deer in the forest. “In addition to safety benefits, we determined that salmon also provides enhanced nutrition over deer, especially in fat and energy.”
Yes, it turns out wolves prefer to fish for food rather than hunt. Makes perfect sense and brings up the question of salmon stock relative to wolf behavior. Perhaps the fish shortages that led to cancellation of the salmon season will also lead wolves towards more risky behavior.
