A moose drowned in a Vermont lake over the weekend after people trying to snap a picture of the animal crowded it and forced it into the water, wildlife officials said.

The moose swam across Lake Champlain from New York to South Hero, Vermont, on Saturday, according to the officials. After the animal made it to shore, onlookers started taking pictures of it. Likely spooked and threatened, it went back into the water, where it became exhausted and then drowned.

Fish and Wildlife Warden Robert Currier told The Associated Press he arrived shortly before the moose drowned and was later removed from the lake.

"It was struggling pretty good at that point. We were waiting for a boat to respond to try to assist it, but before the boat arrived, it had drowned," he said. "It was really rough out there, probably 4- to 5-foot swells and high wind."

It all happened near a bike path that’s popular with tourists.

Currier said moose typically respond to threats by leaving an area or getting aggressive.

"I would advise the public to keep their distance from the animal, give it a lot of space and notify the Department of Fish and Wildlife," he said.
