I guess that what I have here is a "variety" blog. I didn't start out that way and it used to bother me that I couldn't produce a consistent product (so to speak). I've since accepted it and decided to just go-with-it. That being said, I now feel obligated to maintain an ongoing variety of subjects.
Toward that end, today I will post about my next-door neighbors, the Gray Squirrels. (I googled "grey vs gray" and learned that "gray" is the American preference and "grey" is the British.)
Several weeks ago, I saw a squirrel in the lot pulling with all her might on a plastic bag half-buried under snow. She tugged from one side for a while and then moved around to the other side to work on it some more. After ten minutes, she finally gave up. I watched as she came running back and up into the nest (also called a drey) outside my window. She dived into the side of the nest where her babies were.
There is already a plastic bag over the top of the nest placed there several years ago by another protective mother. I had watched as she struggled up the tree with the bag flapping around impeding her progress. She straddled the bag and spent a lot of time and effort getting it in place. I'm sure it still serves to keep the interior of the drey nice and dry for the babies.
This leads me to wonder, is it typical behavior for squirrels to put a "roof" on a nest? Is this something that's being passed on from mother to daughter or is it an evolutionary leap? Which begs the question--if squirrels are capable of evolving, how many years will it take for them to develop the sense to stop running across the street in front of cars!?
