For birds, this time of year, it's all about the music.
But some birds have a different take on song. Rather than singers, they're percussionists.
Every spring, like clockwork, I wake up to an insistent, rhythmic sound. It's a woodpecker tapping a tree with its beak. It sounds to me like a big bird. But every time I gaze up, I can't find it.
Ornithologist Don Kroodsma, a retired UMass biology professor, says it's probably a Downy woodpecker, the smallest around here.
