On Saturday we had a cold front come thru with gusty frigid north winds. Sunny but very cold. Once again, my owl house had a squirrel occupant. Not exactly what I was hoping to see in there. Smart squirrel however. The opening faces south and the tree and overhanging roof protects from the cold wind. Not to mention I added sawdust bedding at the bottom of the box a year ago when it went up.
