A female gray wolf, her mate and at least three pups are the second pack of wolves spotted in Northern California since the species went extinct there in 1924, state wildlife officials said. The gray pups were born this spring in Lassen National Forest to a female wolf of unknown origins. Her mate is the son of OR7, a wolf with a tracking device that was the first of its kind in almost a century to migrate into California from Oregon, the Department of Fish and Wildlife said.Biologists began surveying the Lassen National Forest area in May after they found evidence of wolf presence. On June 30, they captured the 75-pound female gray wolf and fitted her with a tracking collar. An examination revealed she had recently given birth to pups.A day later, Department of Fish and Wildlife biologists returned to the area for a follow-up check on the female and found that a nearby trail camera operated by the United States Forest Service had captured photos of the mother and pups. The gray pups were also photographed playing in front of the camera.
