Northwest Trek veterinarians euthanized a 23-year-old black bear Thursday, saying his declining health suddenly deteriorated.
His female companion was put down last June after struggling with cancer for years.
Black bears typically live 15 to 25 years.
The bear arrived at the Eatonville wildlife park in 1993 after Northwest Trek opened an exhibit built to showcase bears in their natural habitat.
Two brown bears are featured in their own exhibit in the park. Three 9-month-old wolf pups have now taken over the black bear exhibit.
Donna Powell, acting deputy director, said Northwest Trek will work to find more black bears.
Black bears are an integral part of Northwest Trek and our award-winning exhibit, she said. We want to continue that fine legacy of conservation with the species in the future.
