MEDFORD, Ore. (AP) -- A wandering wolf whose trek across Oregon and Northern California attracted worldwide attention could soon fade from the public spotlight.
The Global Positioning System collar that has sent regular electronic pulses to reveal his travels for the past three years has eclipsed its normal life span, and state and federal biologists don't plan to replace it.
The wolf dubbed OR-7 became a celebrity after leaving a pack in northeastern Oregon in September 2011, just days after the state issued a kill order for his father and a sibling for preying on livestock.
Wildlife enthusiasts on six continents have followed OR-7's travels, and will probably never learn how his story ends.
Rob Klavins of the conservation group Oregon Wild tells the Mail Tribune (http://is.gd/2bJDjW ) it's good to have a little mystery in the world.
