The Black-crowned Night Heron (‘Auku’u – in Hawaiian) is an attractive bird to watch. They look like dark silhouettes as they fly with steady beats of their broad wings. As nocturnal feeders, night herons are not be seen often by people. This heron has a stocky, chunky body with short, strong legs and neck, and large red eyes.
- Young Herons have an aggressive, regurgitating reaction to discourage intruders.
- The eggs are green the first day and become pale blue or greenish days later. On hot days the parents may wet their feathers to cool off the eggs.
