A clever wolf repeatedly snuck into a Minnesota ranch. Biologists figured out its MO.
From startribune.com:
ORR, Minn. — Nothing seemed to stop Wolf 04D.
The wildlife biologists thought they had ended a decades-long struggle between rancher and wolf when they built a 7.5-mile fence in the heart of Minnesota’s wolf territory. Even the rancher, Wes Johnson, had high hopes when he came across a wounded deer on his land and saw that the wolves chasing the deer could not find a way around the fence.
Maybe they were gone for good, he thought.
But only a few weeks after the fence was finished, Thomas Gable of the Voyageurs Wolf Project figured out that Wolf 04D had slipped through a gap near the front gate. He plugged the gap.
