Saw both backyard residents this morning just after dawn, sitting in the big tree. (Not the one where they have their love nest.) No hanky-panky, but they stuck close, each following if the other shifted to a different branch. No chasing, no running away, no playing tag. Just companiable breakfasting, not even particularly quick movement along the branches -- for squirrels, who do seem to keep their balance better the faster they go. Both are looking chubby and well-groomed. Then she, followed by he, dove back into the nest, and if they came out again today, I didn't see it happen.
