Winter Mouse House

2-5-14 mouse nest with insulation roof IMG_4629White-footed Mice and Deer Mice are known for their keen ability to recognize a potential winter home when they see it. Abandoned bird nests provide firm foundations, and more often than not, mice will create an insulated roof made out of thistle down or milkweed fluff when renovating a nest. There are exceptions to this rule, however. If you look closely you’ll see that the roof of this nest has a slightly greenish tint, the reason being that the roofing material selected was none other than green insulation “borrowed” from a nearby human dwelling.

  1. Excellent post. Speaking of their keen ability to find a winter home, In the spring, I often discover that mice have wintered in several of the unoccupied bird nest boxes on my property.

  3. Just wanted you to know, everyone I’ve shared this picture with has absolutely loved it, which is odd when you think of how much everyone detests a mouse in the house! Funny little creature that adapts and survives despite the best efforts of man to eliminate it!
    Thanks for the delightful shot, Mary! Keep warm in your travels!
