媒体文件注释
Recorded as the bird flew away from me where it had been feeding in a small stream running out of a man-made lake. Guttural "graaw" call. This is the much more common call than the frog-like croaks recorded in New Zealand (ML 2048). Seems tamer at this location than in New Zealand. Other Behaviors: Depart, Emit Alarm. Habitat: Creek.
