I was sitting in my kitchen with friends one balmy afternoon last month when I heard an unfamiliar chirping sound. I looked around and said, "It reminds me of the sound my smoke detector used to make when the battery was dying, but that was before I moved here, where I don't have any smoke detectors." Mystified, I ran through the list of appliance beeps and chirps, and took a quick walk around the apartment looking for the exceptional blinking light. Nothing. When I returned to the kitchen, Lisa shot me an amused look: "Savtadotty, it's a bird. Outside. In a tree."
