Remember that upset squirrel from yesterday? Here's why she assumed that aggressive posture. See the nose in the hole in the tree? She was warning me to stay away. I backed off right away.
I can't figure out why she would have a nest so close to the ground in a park with dogs and kids running around. But, I guess none are too anxious to call her bluff.
I'll be busy the next few weeks. Commenting will be spotty at best.
