Biologists believe another wolf transplanted into Yellowstone National Park has had a litter of pups, the U.S. Fish and Wildlife Service said Friday.
During a routine monitoring flight over the Absaroka-Beartooth Wilderness area, a biologist with the National Park Service saw one pup walking behind one of the females.
The pup was dark in color. No other pups were observed, but others could have been in the vicinity, the agency said.
The female wolf was part of the Soda Butte pack, one of three groups of wolves released into Yellowstone’s Lamar Valley earlier this year. Fourteen Canadian gray wolves were transplanted to the park as part of an effort to reestablish a Yellowstone wolf population eliminated more than 60 years ago.
A female wolf released in the Rose Creek area gave birth in April to eight pups in southern Montana, near Red Lodge. She and her litter were moved to a one-acre enclosure in the park and remain there.
