The wolverines at the New York State Zoo at Thompson Park are finally united and on exhibit again.

In July 2007, Stinky, the male, contributed to the death of his mate. A year before that, another much older mate died.

But in the 2-year-old Valentine, Stinky, who is 9, has a younger, more playful companion.

"Really the only way I can see the age difference is that she's still much more playful than he is," zoo Director John S. Foster said.

And after three months of gradual introduction, they've gotten used to each other's quirks.

"The female is aware of exactly how far she can push him before the male gets annoyed," Mr. Foster said.

Wolverines usually live in the wild for about 13 years, and the record in captivity is 18.

The zoo plans to breed the wolverines, in part because they are in high demand. Mr. Foster said they are attractive animals for zoos looking to add a North America exhibit.

"They are phenomenally charismatic creatures," he said.

The two are separated at night for security and ease of treating any health issues.

Mr. Foster said the separation has been a standard practice at the zoo for years. And it makes a joyful morning reunion.

"They spend the first 10 minutes rolling and playing and having a grand time," he said.

He suggested visitors check the wolverine exhibit first thing, around 10:15 a.m., when the wolverines are released to see them at their most exuberant.
