A man is currently recuperating from injuries sustained in a startling incident involving a bison at Yellowstone National Park. The event, which has raised concerns about wildlife interactions in the park, took place on Friday, July 10, at the Bridge Bay Campground. Witnessing the ordeal was photographer Mike MacLeod, who managed to capture the dramatic confrontation on video.

According to MacLeod, the man and his grandson were strolling in the vicinity when the seemingly agitated bison became aggressive. The bison, reportedly standing at least six feet tall, charged at the man, employing its left horn to strike him. The impact was so intense that the man was flipped several feet into the air before landing on the ground. “He made a perfect flip and landed on his side,” MacLeod recounted, expressing his surprise at the unexpected nature of the bison’s behaviour.

In the footage taken by MacLeod, the bison initially appears to be rolling around in the dirt. However, after a white truck drives by, it suddenly charges towards the man and his grandson. Despite efforts to escape, including hiding behind trees, the man could not evade the bison’s pursuit, resulting in serious injuries.
Speaking to Cowboy State Daily, MacLeod explained the sequence of events leading to the attack. Just moments before the incident, the bison had shown signs of aggression by charging at a group of children who were taking photographs from a distance. Believing the animal had calmed down, the man and his grandson approached to take pictures, thinking they were at a safe distance.
The National Park Service, which regulates safety protocols regarding wildlife encounters, has guidelines in place urging visitors to maintain a distance of at least 100 yards from larger predators such as bears and wolves, and 25 yards from other animals, including bison and elk. MacLeod noted that the man and his grandson were only walking along the road, but the bison suddenly became agitated once more and charged towards them.
“The bison was sitting in the dust, with its head towards the road. When it began to rise, the grandfather instinctively decided it was time to leave and moved behind trees for safety,” MacLeod recalled. However, the appearance of the passing vehicle is thought to have contributed to the bison’s sudden outburst of aggression.
In the aftermath of the attack, MacLeod took action to divert the bison’s attention from the injured man. “I was genuinely concerned the bison would gore him, so I stopped recording and ran towards the animal, trying to appear as large and formidable as possible,” he said. Several passers-by assisted by notifying park security and calling emergency services.
While the situation was undoubtedly distressing, MacLeod stressed that the victim was not at fault. He described both the grandfather and grandson as respectful visitors who were educated about park safety and the need to maintain a safe distance from wildlife. He acknowledged the bison’s agitation, stating that it seemed unusually aggressive at that moment, charging anything that moved around it. “It’s perplexing why that particular man and child were chosen when there were so many others nearby, some even closer to the bison,” he mused.
The incident serves as a sobering reminder of the unpredictable nature of wildlife behaviour and the importance of adhering to safety guidelines while visiting Yellowstone National Park. The National Park Service has yet to issue an official statement regarding the attack, leaving many to ponder the potential implications for visitor safety in areas where wildlife interactions are common.
As the injured man continues on his path to recovery, this event not only highlights the dangers faced by those in natural habitats but also underscores the need for greater awareness and precaution when encountering wild animals. Wildlife remains a vital part of Yellowstone’s allure, but understanding how to cohabit with it responsibly is crucial for the safety of both visitors and animals alike.
