PREDATORS -- Banff National Park officials are becoming concerned about a well-known, often photographed pack of wolves.

The pack recently was spotted by hikers on Tunnel Mountain, followed a person walking a dog along the Bow River and loped alongside a cyclist on the Bow Valley Parkway, the Calgary Herald reports.

“There was certainly no contact; there was no aggression on the part of the wolves,” said Steve Michel, human/wildlife conflict specialist with Banff National Park, “but all of these are incidents that concern us.”

The encounters come after several high-profile scenes involving the same wolf pack that has been spending time around the Banff townsite since last summer — including a dramatic takedown of an elk on the railway overpass near Banff.

Powerline workers also have been approached by the wolf pack.

Here's more from the Herald's report:

“In addition to it being bear season again and people needing to brush up on all of their bear safety, safety for other wildlife — and, in this case, other carnivores — should be practiced 12 months of the year,” Michel said, noting it’s important to let them know you aren’t prey by appearing large, standing tall, waving arms and shouting.

Bear spray can also be used if a wolf shows any aggression.

“Wolf attacks on humans are very rare,” said Michel. “Wolf attacks on dogs are not rare — they are somewhat common — so people need to be really cautious of their pets and keep a close eye on small children that might be perceived as prey.”
