The last few sunny mornings as I left for work, I heard an unusual bird
singing from the branches of our birch tree. "A sparrow," I thought, "but
a new one to me!" The binos revealed a song sparrow curiously distorting
a song sparrow song: my impression was that it was a brave attempt at
song by a young male who hadn't quite got all the trills and glissando's yet.

Do birds 'grow into' their mature voice and complexity of song?
