Here is the squirrel taking a look at Tom who is taking her photo. He reports that she had her young nearby in a much higher tree. He says "Just when I had about given up hope, I discovered after much surveillance that mother squirrel apparently decided to keep her young in a much higher tree down the street until they were just a wee bit older. Today, she chose to bring them back to her luxury apartment in our tree. Maybe the new curb appeal of a high climbing rose in bloom did the trick."
