The public is invited to vote on names for five endangered red wolf pups recently born at Point Defiance Zoo & Aquarium.

Zoo staff members have selected two separate groups of names related to the wolves’ native North Carolina habitat.

The first set of possible names is of counties in North Carolina: Bladen, Haywood, Hyde, Nash and Onslow. The second set is from trees native to the state: Fraser, Hickory, Hawthorn, Juniper and Sumac.

To vote, go to www.pdza.org and click on the red wolf slide when it scrolls across the top of the page.

The pups were born May 13 to mother Millie and father Graham. It’s the first litter born at the zoo in 25 years.
