Biologists have found evidence that OR-7's Rogue Pack has further expanded by a second set of pups. The US Fish and Wildlife Service and Oregon Department of Fish and Wildlife has releases a video that shows the new wolves playing in the Cascades east of Medford. The video can also be seen on the department’s Oregon Wildlife Viewing Facebook page.

The video has been made of a remote camera, which has captured images of Rogue Pack wolf yearlings born in spring 2014. They can be seen playing the Rogue River-Siskiyou National Forest on June 24, 2015.

For now, the new pups have not been seen, but the researchers were able to know about them after finding pup scat in the area. Wildlife officials said that it is common for wolves to have pup every season. Oregon Department of Fish and Wildlife State wolf coordinator Russ Morgan said that it was not surprising for them that they had pups again.

Morgan added, “That doesn't necessarily mean that it's a successful reproductive attempt for this year. There's still a lot of year to go before we know if those pups are also recruited into the adult population”.

In 2011, the OR-7, the wolf, separated from his pack in Northeast Oregon. It covered 1,200 miles across the state and entered into Northern California. Since the 1920s, this wolf became the first-known, free roaming wolf in California.

The OR-7 came back to Oregon and settled with a female wolf and now, its family is expanding. The family is the first pack in southwestern Oregon in over six decades.
