It's hard to imagine that the boisterous Steller's Jay could possibly have a softer aspect to its blustery behavior. But it does. It's called the "whisper song." Male jays use this whisper song during courtship, and it also emanates from solitary birds for no apparent reason. Quietly, the bird extends its head slightly forward, slowly turns it from side to side, and begins . . . very softly . . . to . . . sing.
