 Laysan Finch - Wikipedia, the free encyclopedia
The Laysan Finch is named for Laysan, the island to which it was endemic on its discovery (it was subsequently introduced to a few other atolls).
On its discovery the Laysan Finch was an endemic resident to the small island of Laysan, along with the Laysan Rail and the Laysan Millerbird.
The Laysan Finch is a generalist, feeding on seeds, small insects, fruits, carrion (of seabirds and Hawaiian Monk Seals), and the eggs of nesting seabirds.

 The Life History of the Laysan Rail
The biology of the Laysan Rail is probably similar to that of other island-dwell- ing rails such as Porzana tabuensis and to such continental forms as the fl rails (Laterallus) and the yellow rails (Coturniculus).
The principal observers of the Laysan Rail and the dates of their observations in the field 6n Laysan Island are: Palmer and Munro, June 16-28, 1891; Schauinsland, June 24 and throughout the summer of 1896; Fisher, May 16-23, 1902; and Dill, April 25-June 5, 1911.
The rail was seen by sailors of the Moller in 1828, on Laysan Island, according to Kittliz (Rothschild, 1900:v).

 Laysan crake - Porzana palmeri: More Information - ARKive
Endemic to Laysan Island in the Hawaiian archipelago, the Laysan crake briefly occupied several other Hawaiian Islands in the years before its extinction, as attempts were made to conserve it via translocations (1).
This small, flightless member of the rail family was very rapid on the ground (3), and would feed opportunistically on invertebrates and the eggs of seabirds.
The Laysan crake was initially threatened by the habitat destruction caused by rabbits and guinea pigs that were introduced by guano diggers.

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 Laysan duck was also hunted for sport and for food, but it was the devegetation caused by the rabbits that drove the duck close to extinction.
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.

 War and the Birds of Midway Atoll
The main factor in the extermination of the rail was the overrunning of both islets with rats, which escaped to Midway from ships in 1943.
The absence of the Laysan Finches on Midway was attested by.
Atsatt (1945:49-51) states that the disappearance of the finch was as abrupt as that of the rail, but the rail was exter- minated first.

Laysan finches, along with the other Hawaiian honeycreepers, were formerly considered to be in a separate family, the Drepanididae, but are now considered to be a unique subfamily, the Drepanidinae, under the family Fringillidae (08, 14).
Laysan finches have also been seen entering seabird burrows, but it is unclear what they might be getting or doing there (39); possibly they are looking for invertebrates or preying on eggs.
Laysan finches on Laysan Island have been observed feeding on leaves, stems, flowers, and seeds of Sesuvium portulacastrum (03,49); leaves and seeds of Eragrostis variabilis (03,15,39); leaves, seeds, stems, roots, and buds of Boerhavia diffusa (03,10,15,31,52); leaves, stems, seeds, flowers, and seedlings of Tribulus cistoides (03,10,15,31,39,49,52); leaves, apical buds, and seeds of Portulaca spp.

 Laysan duck nests are nurturing hope - The Honolulu Advertiser - Hawaii's Newspaper
This endangered Laysan duck is one of three transplants that have built nests on Midway's Sand Island.
Three species — the Laysan rail, the Laysan honeycreeper and the Laysan millerbird — became extinct, and by 1911 records showed there were only 11 Laysan ducks left.
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.

 LAYSAN TEAL IN CAPTIVITY
CONCLUSION The size of the eggs of the Laysan Teal, and the size of the ducklings are both extraordinarily large in proportion to the adult birds which are the size of teal.
Laysan Island is about two miles long and one mile wide with a small brackish pond in the center, and lies in the Leeward chain of the Hawaiian Archipelago, about 800 miles northwest of Honolulu.
At a later time, the date is not clear, the rabbits on Laysan were extermi- nated with the result that the vegetation has now been restored and there is a prolific growth of grasses, portulaca, casuarina, solander and a few coconut palms.

 News Release  - NOWRAMP Expedition
In just shy of one decade, a handful of dedicated staff and volunteers have been able to assist Laysan island to transform itself from weed-stricken place where wildlife were more challenged to survive, to a place where native plants are once again abundant and bird populations are on the rebound.
In 30 years, the impact of guano mining, feather poaching, and rabbits combined, caused a 97% crash in the Laysan albatross population alone, which went from an estimated one million in 1891 to about 30,000 in 1923.
Like the millerbird and honeycreeper, the rail was endemic to Laysan, meaning it only existed on the island and no where else on the planet.

Rabitts that were introduced to Laysan in the late 1800's ate all the vegetation, leaving a barren wasteland, and just after this film was taken a strong storm came through and blew the last of the birds off the island, never to be seen or heard again.
Complete habitat destruction by introduced rabbits on Laysan pre-1923 wiped the species out of it's home area, and an introduced population on Midway died off from the accidental introduction of rats and mosquitos during the Battle of Midway in 1942.
The last rail was seen on Eastern Island in Midway in June 1944.
