American Red Wolf Pups Fostered into the Wild in North Carolina.
The Saint Louis Zoo placed three zoo-born American Red Wolf pups into a wild litter at a North Carolina wildlife refuge, and trail cameras later confirmed all three were alive.
Three critically endangered American Red Wolf pups born at the Saint Louis Zoo Sears Lehmann, Jr. Wildlife Reserve were placed with a wild red wolf family in North Carolina this spring, the zoo announced on August 31. The zoo says it is the first time pups from its reserve have been fostered into the wild. The effort was part of species recovery work led by the U.S. Fish and Wildlife Service (FWS), in partnership with the Association of Zoos and Aquariums (AZA) Saving Animals from Extinction (SAFE) Program.
The pups joined a wild litter on the Alligator River National Wildlife Refuge in northeastern North Carolina. According to the zoo, fostering adds genetic diversity to a wild population on the brink of extinction. It says that diversity helps populations resist disease and limits the effects of inbreeding. Regina Mossotti, the zoo's vice president of animal care and leader of the SAFE program, said: "With less than 40 American Red Wolves left in the wild, fostering is an important tool for the species."
Timing is tight. A foster must happen within the first 14 days of a pup's life, when wolf mothers bond with their young and are most likely to accept new pups. FWS monitors breeding among wild wolves, while SAFE coordinates breeding of wolves in professional care and looks for zoo-born pups within that two-week window. The zoo reports that its litter was the only one born in professional care in the right timeframe in 2026.
On April 20, zoo animal care and veterinary staff collected three pups, each seven days old. After a health exam, the pups traveled with zoo staff to the refuge and received hour-by-hour care on the way. FWS biologists placed them in a wild den and monitored it to make sure the wild mother returned.
Several months later, when the pups began exploring outside the den, refuge trail cameras confirmed all three zoo-born pups were alive. The zoo reports that the wild mother accepted them. Because her litter was large, a few wild pups were also placed into the zoo's litter at the reserve, a process called cross fostering. The zoo describes this exchange of genetics between wild and zoo-managed wolves as rare.
The page says fewer than 40 American Red Wolves remain in the wild, all in northeastern North Carolina. The zoo plans to post photo and video updates on its website.
