Rat on the Run

In some cities, rats are annoying pests. But on St. Paul Island in Alaska, the rodents can mean disaster. So when someone reported a possible rat sighting in June, the 400 residents of the island sprang into action. 

St. Paul is home to a wide variety of wildlife, including fur seals and rare seabirds. These birds nest on the island but get their food from the ocean.

St. Paul Island is in the Bering Sea, about 300 miles off the coast of mainland Alaska.

Officials are constantly on the lookout for rats, which can sneak onto St. Paul on ships. Even one rat can pose a threat by killing and eating seabirds and disturbing the island’s ecosystem.

After the June sighting, a “rat strike team” began looking for the rodent using motion-sensor cameras and special lights that can detect rat urine. The team is also setting traps. Officials are worried that the rat could be pregnant.

“Rats will keep breeding and doing harm to wildlife forever,” says Steve Delehanty. He’s a manager at the Alaska Maritime National Wildlife Refuge. The group works to protect wildlife.

The last time a rat was seen on the island, in 2018, it was on the loose for nearly a year. The residents of St. Paul won’t stop until they find this one.

“They want to keep their island healthy and full of wild birds,” says Delehanty.
