Wolves use trails created by humans for convenient hunting and easier access to prey
From The Conversation:
Zoom in and explore the northern boreal forests of western Canada on Google Earth and you’ll see long straight lines making their way through the forest. These lines are cleared trails through the forest to extract resources, creating roads for forestry and seismic lines searching for underground oil and gas deposits.
Now picture yourself faced with the task of moving across this landscape: Will you push your way through dense trees and underbrush, or will you choose to walk on the trails?
