Koloa maoli, Hawaiˊi's endemic duck species, served as guides for the legendary blind warrior king Imaikalini.

Did you know that Hawaiʻi has an endemic species of duck? This native waterfowl, called the Koloa maoli, resemble introduced mallard ducks, but they have a quack all their own.

Koloa used to inhabit nearly all of the islands, but now their largest populations are on Kauaʻi and Niʻihau.

While they nest year-round, the peak time for duckling spotting is in the mid-to-late spring. A female Koloa may lay and hatch up to 10 ducklings at a time!
