The Mallard are also to be found in Honolulu. But I can actually see they seem to be a bit different from other mallards I´ve seen. One thing is the bill. On the female it seems to be blue. And the butt is kept higer then usual. Very obvious on the chicks. They usually keep the tail feathers down.

This one seems to be Hawaiian Duck - Anas wyvilliana, a close relative to the Mallard.
Snippet: JustificationThis species qualifies as Endangered because it is inferred to have a very small and fragmented range on a few islands, where wetlands are being lost and degraded, and where hybridisation is slowly reducing the number of pure individuals.
