Saw several squirrel tracks in the snow today. Only saw one squirrel hour before dark. Look for areas the have leaf nest in the trees or hollow den trees. They like to get in out of the cold at night...often more than one will den up together...perhaps body heat plays a role.
I think the squirrels knew we were going to have a cold Winter...during archery season I watched several squirrels at several locations carry leaves up their den trees and poke them inside.
took a 2 mile round trip walk on Monday to put some cams out, this was in the afternoon. Saw a ton of tracks but not a single squirrel....so my guess would be they are getting out mid morning when the sun is above the tree line.
