This morning at about 6:45am some loud chipping was heard outside my bedroom window. It didn't quite sound like a cardinal who would normally be outside the window at this time. Bill rolled over in bed and asked, "downy woodpecker?". "Not quite," I whispered. Finally I rose from bed and looked out to see a very agitated white throated sparrow. These guys normally feed on the ground and he was eyeing my second story feeder and chipping like crazy. I sensed he wanted to come in but the two thugs (pigeons) sitting on the ledge proved to be a deterrent and he flitted elsewhere.
