I have been swamped at work, and had not checked in on the squirrel family in well over a day.
When I got home last night, I activated the video monitor and saw the above scene.
At first I thought the babies might be well-hidden, but usually there's some thrashing after while.
Nothing had changed this morning.
Apparently Mrs. Squirrel likes to move the babies. She moved them 19 days ago, then brought them back a week later.
This may be the last we see of the four babies in the nesting box -- or not. These squirrels are impossible to predict.
What I found strange is that the mom must have gone back after moving the babies and covered the indentation where the four babies nestled -- as if she were covering their tracks.
In a week, I'll put out that "room for rent" sign and advertisement again.
