Lincoln Park Zoo Welcomes a New Male North American River Otter

Chicago (June 10, 2025) – The newest resident at Lincoln Park Zoo is making quite the splash—literally! Tucker the North American river otter has arrived and can be seen exploring his new habitat at Pritzker Family Children’s Zoo.

Tucker is a 6-year-old adult river otter who hails from Roosevelt Park Zoo in Minot, North Dakota. His transfer was recommended by the North American River Otter Species Survival Plan®. This is a collaborative population management effort among institutions within the Association of Zoos and Aquariums.

“In the short time that Tucker has been here, he’s already impressed us with his intelligence. He’s quick to engage with puzzle feeders and has a playful personality,” said Curator Dan Boehm. “Animals have food preferences just like us, and it turns out that Tucker is a big fan of rib bones. So, we’ve been working with the zoo’s Nutrition Center to make sure his individualized diet includes this preferential snack.”

North American river otters are semiaquatic animals that live in areas with permanent water sources, such as rivers, creeks, and streams. When zoo guests visit Tucker, they can catch him swimming or scampering around on land. River otters have varied social structures; some live alone, while others live in families or groups of adult males.

North American river otters are considered a keystone species, meaning that they have a sizable impact on their native ecosystem. As a result, any substantial decline in their population can have serious negative impacts on the entire system. A healthy North American river otter population in the wild signals that the area has a high water quality that can support life.

The North American river otter population in Illinois is a true wildlife recovery success story. By the end of the 1980s, habitat loss due to human development, poor water quality, and overhunting landed river otters on the state’s endangered species list. Over the following three decades, efforts to improve waterway quality and protect habitats throughout Illinois, combined with a well-executed reintroduction plan, has helped the North American river otter population come back strong with an estimated 15,000 individuals living in all 102 counties in Illinois. For the past decade, North American river otters have even made themselves at home on the Chicago River; last year, they were even caught on camera by Lincoln Park Zoo’s Urban Wildlife Institute for the first time!
