SAN FRANCISCO (AP) -- Wildlife officials say California's lone wolf has returned to Oregon.
A GPS device tracking the movements of the gray wolf known as OR-7 shows he left California and crossed into Oregon around noon Thursday.
An official with the Oregon Department of Fish and Wildlife told the San Francisco Chronicle (http://bit.ly/wrTss7 ) that the wolf, also known as Journey, was in Oregon's Jackson County Friday night.
Wildlife officials believe the wolf returned to Oregon after a futile search to find a mate in California.
When he did enter California in late December, officials said he was the first wolf to roam anywhere in state since 1924.
During his journey, OR-7 impressed wildlife experts with his endurance.
The device tracking his movements shows he covered 20 air miles a day as he travelled through California's Shasta and Lassen counties before heading back to Oregon.
