A forest world is a 3D world to a Lynx. As you noisily march through the woods, the cat zips up a tree and watches your passage from a comfortable limb.
Our grouse (Ruffed, Franklin's and Dusky) are principally birds of the forest floor but roost in trees at night. Rabbits on the ground.
Our Lynx and Bobcats live mostly on the forest floor as well. They're no threat to people, corned or cornered.
I can put you in front of an active Lynx den site in about 20 minutes from my house.
You could sit there for a week and see nothing as they come and go = ghosts, both day and night.
If they've got a litter of kits, we might see them all out in some grassy clearing in October.
Cougar/Puma/Mountain Lion have to be taken seriously. In the winter, they have come into the village and killed a couple of the resident deer.
It becomes extremely worrisome for the parents of small children going to school in the dark and coming home in the dark, mid winter.
The soft snow makes a silent world.
