  Hawaiian Duck - Wikipedia, the free encyclopedia
The former range of the Hawaiian Duck included all of the main Hawaiian islands except the island of Lana'i.
The Hawaiian Duck was exterpirated on all other islands, but was subsiquently reestablished on Oahu, Hawaii, and Maui through release of captive-reared birds.
However, all the Hawaiian Ducks in the reestablished populations have bred with feral Mallard ducks and have produced hybrid chicks.

 Laysan Duck - Wikipedia, the free encyclopedia
This duck is related to the Mallard, and has sometimes been considered to be an island form of that species.
Subfossil remains found on the major Southeastern Hawaiian islands have been determined to belong to this species; it became extinct everywhere except on Laysan before European contact due to hunting and introduced predators, whereas the more adaptable Hawaiian Duck still survives in somewhat larger numbers.
This duck nests on the ground under bushes near the lagoon, and is gregarious outside the breeding season.

The Hawaiian Duck or koloa, is generally mottled brown and has a green to blue speculum (the distinctive feathers on the secondary wing feathers) with white borders.
The largest number of Hawaiian ducks can be found at the Hanalei National Wildlife Refuge and at Alakoko Pond in Huleia Valley, both on the island of Kaua`i.
The Hawaiian duck is endemic and used to be found on all the main Hawaiian islands except Lana`i and Kaho`olawe.

The male duck is usually 19 to20 inches in lenght while the females is 16 to 17 inches in length.
The ducks are able to breed at one year of age and nest year-round, but the main breeding season is between January and May. The Hawaiian Duck can produce 2-10 eggs.

The small, brown Hawaiian duck is closely related to the mallard, but both sexes are similar in appearance to a female mallard.
The Hawaiian common moorhen is similar to a coot, but has a red shield over its red and yellow bill and very long, slender toes that allow it to walk on floating wetland plants.
The fl and white Hawaiian stilt is a slender wading bird with distinctive long, pink legs, and is considered a separate subspecies of the fl-necked stilt found in North America.

 Domestic mallards in FL
Both Florida’s mottled duck and the mallard are part of a worldwide group of about 20 species of ducks that are so closely related that they collectively are called the "mallard complex." However, when mottled ducks and mallards come in contact during the breeding season they create hybrid offspring that are different from either parent.
Most ducks found on canals and in parks are a breed of mallard, muscovy, or a mixture of both (yes, mallards hybridize with muscovy ducks too).
Scientists are already detecting mallard genes in the mottled duck population and are concerned that interbreeding with mallards may lead to the demise of Florida’s mottled duck as a distinct entity.

The Laysan duck was believed to be endemic to Laysan Island (it was found historically on neighboring Lisianski Island, but was extirpated in the early 20th century), but in 1995 evidence from bones revealed that the duck once inhabited the islands of Hawaii, Molokai, Maui, Oahu, and Kauai.
The ducks are being released with their aviary mates in groups of two, and are monitored closely for 48 hours before the next group is released.
Laysan ducks are teal sized, between 15 and 17 inches in length, are brown with a bright green-blue to purple speculum (the distinctive feathers on the secondary wing feathers), and have a white area eye ring.

A Safe Harbor agreement signed in December 2001 is intended to benefit two endangered waterfowl, the Hawaiian duck or "koloa" and the Hawaiian goose or "nene" ("NAY-nay").
In coastal areas the ducks are interbreeding with wild mallards, a closely related species.

Twelve Laysan Duck were released by the U.S. Fish and Wildlife Service on Pearl and Hermes Reef in 1967 but none were reported after 1967 (Sincock and Kridler, 1977, Berger 1981).
The main food taken by the ducks is macroinvertebrates which the birds find in the littoral zone of the lake, in shallows and on the mudflats, as well as in sand under vegetation.
Ducks will also feed on larvae and pupae of noctuid moths which they find under vegetation and in sand, as well as feeding on fly larvae in the lake by dabbling and sifting with their bills.

 Laysan duck nests are nurturing hope - The Honolulu Advertiser - Hawaii's Newspaper
Before the Midway transfer, the ducks were found only on 1,000-acre Laysan Island, where the duck population is estimated at 400 to 600.
The ducks were placed in aviaries for a few weeks before their release, and radio transmitters were attached to each bird for tracking.
Klavitter said biologists have been tracking ducks on Laysan that were the same age as the Midway birds, but only half had survived due to greater competition for resources and limited food and water.

The Hawaiian Duck is small and brownish with orange legs but has a highly variable plumage with some birds having various amounts of red-brown, chestnut, mottling, streaks and in the males often a green sheen to the head and neck.
In the past the Hawaiian Duck has often been treated as a race or sub-species of the Mallard, and it is obvious from its behaviour and morphology that the species is closely related to the North American Mallard complex (Phillips 1912).
The Hawaiians referred to the Koloa as Koloa Maoli to differentiate the species from migrant ducks which visit the islands, mainly during winter.

 Laysan ducks introduced on Midway - The Honolulu Advertiser - Hawaii's Newspaper
The Laysan duck, whose scientific name is Anas laysanesis, had the smallest geographical range of any duck species in the world, with approximately 500 birds living on Laysan.
Laysan ducks, between 15 and 17 inches in length, are brown with bright blue-green to purple feathers on their secondary wing feathers.
Because the ducks were located in a single habitat, they were vulnerable to extinction, so biologists felt that creating a second population would increase chances of its recovery.

A very shy, dark brown duck, the Hawaiian Duck is in danger from both loss of wetland habitat and genetic swamping through interbreeding with feral Mallard Ducks.
In 2001, a Safe Harbor Agreement was signed between the Umikoa Ranch, the U.S. Fish and Wildlife Service, and Hawaii's Department of Land and Natural Resources under which the ranch owners agreed to restore and maintain 180 acres of habitat for 20 years at the high elevation ranch on the island of Hawaii.

 Social & cultural values of Hawaiian Ramsar site
Hawaiian agricultural sites, and Kawainui Marsh and surrounding environs have provided significant information about Hawaiian culture, particularly having to do with the relationship of the early Hawaiians to the environment of a windward valley (Handy et al., 1972; Kelly and Clark, 1980; Kelly and Nakamura, 1981; Drigot and Seto, 1982).
Surrounding the 180 hectare (450 acre) former freshwater fishpond and its tributaries are the remnants of walled water gardens (lo'i) in which the Hawaiian staple crop, taro (Colocasia esculenta), was grown for one of the largest native Hawaiian settlements (Kelly and Nakamura, 1981; Drigot and Seto, 1982).
There is Hawaiian legendary history associated with the Kawainui Marsh area, including a legend of Hau-wahine, a guardian spirit over the Kawainui fishpond, called a mo'o, and a famous mythological tree, Makalei, which had the power of attracting fish (Kelly and Nakamura, 1981).
