A man in Banff, Canada who was testing out his new motorcycle on Saturday made a close encounter with a wolf who was trying to chase him on Highway 93.
Instead of speeding up even more to lose the wolf, Tim Barlett started snapping photos of the incident.
The wolf was so determined to get to Barlett that he crossed a lane of traffic.
"It sort of sped up initially; it gave a real good burst of speed," Barlett said. "And then after that it just trotted along beside me, but it probably got within three or four meters."
Barlett said it reminded him of a border collie he had that used to chase bikes.
Surprisingly determined, the wolf kept up with him for about a kilometer, and then came to a stop. He then headed back into a nearby forest.
While others might get the wrong idea, Barlett said he wasn't trying to provoke the wolf.
"I got six really good shots and … the one that came in nice and close, he had his ears pinned right back and he was in full gallop," Barlett said. "It looked really cool."
Michelle Macullo of Parks Canada said it is a rare occurrence, as wolves are difficult to spot.
"It's likely that this animal is habituated, so what that means is this animal has lost some of its natural fear of humans…so it's definitely cause for concern for us," she said.
Many wolves live in the area because people were feeding them in the past. An alert was issued last year when photos of a wolf being fed rice cakes became public.
"If people see animals roadside and if they are … being aggressive or doing things like pursuing folks, we need for people to call us because the more information we have, and the sooner they call, the sooner we can go and investigate," Macullo said.
