|Molokai

|Known from subfossil remains.

|

|Zapornia palmeri

|Laysan

|Disappeared from Laysan in 1923 after feral rabbits ate all the vegetation in the island. Previously, the species was introduced to other islands in an attempt to save it from extinction, establishing successful populations in Midway (Eastern and Sand islands). In 1943, military construction in Midway accidentally introduced black rats, which exterminated the rails by either June 1944 or June 1945.

|120px

|Zapornia sandwichensis

|Hawaii (island)

|Last collected in 1864; claims of further survival are unsubstantiated. The nominate subspecies Z. s. sandwichensis lived on the leeward side of the island of Hawaii and the subspecies Z. s. millsi on the windward side. It coexisted peacefully with the Polynesian rat but might have been driven to extinction by the black rat. Mongooses were blamed by some authors, but they were not introduced to the island until 1883. Hunting, deforestation, predation by pigs, cats, and dogs, and introduced diseases from poultry may have been contributing factors to its extinction.

|Holocene eagle fossils have been found on Oahu, Molokai, and Maui. The absence of eagle fossils from other Hawaiian islands might represent a true gap in distribution or a deficiency in the fossil record. Based on DNA research, these fossils represent the white-tailed eagle (Haliaeetus albicilla) or a very close relative. The Hawaiian eagle was an isolated, resident population in Hawaii for more than 100,000 years, where it was the largest terrestrial predator. Its extinction could have been related to human-induced ecological changes, although there is currently no direct evidence for temporal overlap with humans.

|Corvus hawaiiensis

|Hawaii (island) and Maui

|Historically recorded on the island of Hawaii, where it was persecuted as a nuisance during the 19th century. Fossils indicate that this species or a very similar one was also found on Maui before European contact. The last wild pairs bred on the slopes of the Mauna Loa in 1992, by which time there were only 11 or 12 individuals left. One egg was laid in 1996 but didn't hatch, and the last pair was sighted in 2002. A captive population exists, but a release program in 1993-1999 ended in failure.{{Cite iucn |year=2016 |title=Corvus hawaiiensis|author= BirdLife International |page=e.T22706052A94048187 |doi=10.2305/IUCN.UK.2016-3.RLTS.T22706052A94048187.en|doi-access=free }}

|Last two individuals recorded in 2004; one died shortly after being captured. The precise causes of decline are unknown. Suggestions include habitat destruction and modification, spread of disease-carrying mosquitos, pig activity, predation by rats, cats, and small Indian mongooses; and the decline of native Hawaiian snails as a result of predation by rats and the garlic snail Oxychilus alliaricus.{{cite iucn|title=Melamprosops phaeosoma|page=e.T22720863A153774712|author=BirdLife International|date=2019|volume=2019|access-date=18 November 2021|doi=10.2305/IUCN.UK.2019-3.RLTS.T22720863A153774712.en}}

|Known from fossils on Maui and Oahu. Based on its disjunct distribution, the species might have occurred on all main islands except the island of Hawaii and perhaps Kauai, although more fossils are needed for confirmation. The primitive koa finch populations from Oahu and Maui might represent two distinct species, but more fossils or genetic data are necessary.

|Hemignathus affinis

|Maui

|Last confirmed sighting in 1896, though several "unconfirmed detections" happened in 1986-1998, and a single male was seen by qualified observers in the same area in 1995. The species's forest habitat has been eliminated for cattle ranching or otherwise degraded by introduced ungulates, which also spread alien plants and disease-carrying mosquitos. Predation and competition with introduced birds and insects has also been suggested.{{cite iucn|title=Hemignathus affinis|page=e.T103823664A104234257|author=BirdLife International|date=2016|volume=2016|access-date=17 December 2022|doi=10.2305/IUCN.UK.2016-3.RLTS.T103823664A104234257.en}}
