Well, it's a small backyard. The number of squirrels in residence is right now something of a mystery, but I can report that a pair of robins have been perched above the squirrel nest all morning. The birds are about 15 feet apart and just sitting there. I think it's a male and a female, though the sun's at a bad angle for figuring that out. That tree had a few more branches before Irene, and the bigger tree had significantly more -- it lost a whole limb. I wonder if these guys used to nest here and, now that we have a warm sunny day, are trying out the squirrel tree to see if it's worth staking a territorial claim to?
