Or maybe it was Squeeze -- hard to tell, seeing as how whoever it was popped out of the nest this morning, stood on a branch right in front of the woven branches (thus being hard to distinguish) and scratched furiously at his/her flank, then the other flank, then the chest. Then popped back in. I'm imagining the squirrel pillow-talk conversation:

"You're driving me crazy! Stop scratching! Or go outside if you have to do that. Don't come back until you're done!"

Meanwhile, it rained yesterday, but no new building has gone on. I'm beginning to think maybe the woven structure Squirrely worked so hard on after the east-side collapse isn't a windbreak, or a shingle-less roof, but a structural element anchoring the whole nest back to the tree.
