The red panda population at the Virginia Zoo grew significantly earlier this summer, The Virginian-Pilot reports. On June 18, mother Masu and father Timur welcomed a brood of triplets into the world, bringing their total number of offspring up to five. The three red panda babies are currently without names, but the zoo is giving a few lucky bidders the chance to change that.

Red pandas are endangered, with fewer than 10,000 of them living in their natural habitat in the Eastern Himalayas. Red panda breeding programs, like the one at the Virginia Zoo in Norfolk, are a way for conservationists to rebuild the species's dwindling numbers.

In 2017, Masu relocated to Virginia from the Denver Zoo as a juvenile. Zookeepers paired her with a male red panda there named Timur, and in June 2018, she delivered twin cubs named Adam and Freddie. Red pandas typically breed in the spring and summer months and usually have just two babies at a time. But when Masu gave birth again this past June, she had three tiny cubs.

The three new red panda babies each weighed about 5 ounces when they were born and weigh roughly a pound today. Masu has been moved to a private, climate-controlled den to care for her young and will be returned to her original exhibit with her cubs sometime this fall.

By the time they make their debut, the youngest red pandas at the Virginia Zoo will have names, chosen not by the zoo, but by members of the public. Starting yesterday, August 19, and ending August 30, the zoo is holding an online auction for the naming rights of each of the three red panda cubs. As of press time, the honor of naming the two boy red pandas has already been sold for $2500 each, and the current bid for the girl stands at $1000. All the money that's raised will be donated to the Zoo’s conservation partner, the Red Panda Network.

Perhaps due to the results of previous public naming contests, the Zoo did lay out a few stipulations for the winning bidders. It won't accept any repeat names of red pandas that have lived there in the past. Additionally, "any racial, religious or ethnic slurs, explicit language, obscene content, reference to alcohol, drugs or other illicit substances or otherwise unlawful, inappropriate, objectionable, or offensive content" will be rejected. All name submissions from the winners are due to the zoo by September 9.
