I relied on sound even when I wasn't able to spot the bird. I did hear the yellow-bellied sapsucker, but I didn't count it because I wasn't sure which kind of woodpecker I was hearing. A few days after the count, though, I saw the female yellow-bellied sapsucker on the sugar maple out front. I enjoy watching a woodpecker. According to the maps, the yellow-bellied sapsucker is a winter bird here in central NC and will be heading farther north for the summer breeding season.
(The colors really blend with the bark on the maple.)
