PHOENIX (AP) -- Wildlife managers say two Mexican gray wolf pups from an Arizona pack are thriving with their new family in New Mexico.
Biologists in May transplanted a pair of 2-week old pups born in a large litter to another pack of wolves with a smaller litter and more rearing experience.
Wildlife managers have been troubled by the survival rates of wild-born pups. The goal with cross-fostering is to improve the genetic health of the endangered predators as they are reintroduced to the American Southwest.
The technique has worked with red wolves on the East Coast. This marks the first time it has been tried with Mexican gray wolves.
The Arizona Game and Fish Department said this week that a trail camera photo shows that the pups are alive and doing well.
