Der bestehende Eintrag kommt vielleicht daher, dass der Vogel früher schlicht als "robin" bezeichnet wurde. Sagt zumindestens das Audubon Bestimmungsbuch.

The mainstay of the American Robin is earthworms. It hunts on lawns, standing stock-still with head cocked to one side as though listening for its prey but actually discovering it by sight. Formerly called simply the "Robin".
