Don't spook the goose.
A high school golfer playing in a weekend tournament learned the hard way how protective geese can be about guarding a nest.
In photos that have gone viral, a student can be seen rolling on the fairway as a goose dive-bombs him repeatedly, sending his clubs flying and leaving him prone on the grass.
Michigan mom Devon Gilson-Pitts was tooling around in a golf cart, watching her two sons play and shooting photos for the Concord High School yearbook.
Then she heard yelling. A male goose was going after a poor golfer who was trying to get away. The goose actually kicked the boy, Gilson-Pitts told InsideEdition.com Tuesday. "He was rolling," she said. "His clubs had dropped out of the bag."
As his teammates and Gilson-Pitts and her husband tried to help, the incensed goose would not let up, she said.
"We kept trying to get (the upended clubs) but he kept hissing at us," she said, referring to the goose.
The golf course had erected a sign warning there was a nest on the fairway, but apparently the golfers weren't keep a respectful enough distance.
"It took four golf carts and four coaches to get (the goose) away from the clubs," she said. Meanwhile, Gilson-Pitts kept shooting.
"They're not nice. Birds are not nice," she said.
The boy, identified by The Detroit News as Isaac Couling, continued playing and parred the hole, he told the paper.
Gilson-Pitts, thinking nothing of it, sent her images to her sons' coach so they could be posted on team's social media page.
"The school put it up on Twitter, and it went crazy," she said. "I had calls coming in from Spain, the UK, in the middle of the night."
But Couling wasn't the only bird victim on the course. As teams continued to play through, "I heard a kid screaming from three holes away," she said.
