Question: What animal has migrated from Souteast Asia and caused the extinction of The Kauaʻ i ʻ ōʻ ō in Hawaii?

full_context: Document 1: Hawaiʻi ʻōʻō: The Hawaiʻ i ʻ ōʻ ō ("Moho nobilis") is a member of the extinct genus of the ʻ ōʻ ōs ("Moho") within the extinct family Mohoidae. It was previously regarded as member of the Australo-Pacific honeyeaters ("Meliphagidae").
Document 2: Kauaʻi ʻōʻō: The Kauaʻ i ʻ ōʻ ō or ʻ ōʻ ōʻ āʻ ā (Moho braccatus) is a member of the extinct genus of the ʻ ōʻ ōs ("Moho") within the extinct family Mohoidae from the islands of Hawai'i. It was previously regarded as member of the Australo-Pacific honeyeaters ("Meliphagidae"). This bird was endemic to the island of Kauaʻ i. It was common in the subtropical forests of the island until the early twentieth century, when its decline began. Its song was last heard in 1987 and it is now probably extinct. The causes of its extinction include the introduction of the Polynesian rat, domestic pig, and mosquitoes carrying avian disease (avian malaria and avian pox), as well as habitat destruction.
Document 3: Polynesian rat: The Polynesian rat, or Pacific rat ("Rattus exulans"), known to the Māori as kiore, is the third most widespread species of rat in the world behind the brown rat and black rat. The Polynesian rat originated in Southeast Asia, and like its relatives, has become widespread, migrating to most Polynesian islands, including New Zealand, Easter Island, and Hawaii. It shares high adaptability with other rat species extending to many environments, from grasslands to forests. It is also closely associated with humans, who provide easy access to food. It has become a major pest in most areas of its distribution.
Document 4: Rat: Rats are various medium-sized, long-tailed rodents of the superfamily Muroidea.
Document 5: Longtail (rat): On the Isle of Man, longtail is a euphemism used to denote a rat, as a relatively modern superstition has arisen that it is considered bad luck to mention this word. The origins of this superstition date to sea-taboos, where certain words and practices were not mentioned aboard ship, for fear of attracting bad luck (or bad weather).
Document 6: Nosopsyllus fasciatus: Nosopsyllus fasciatus, the northern rat flea, is a species of flea found on domestic rats and house mice. Northern rat fleas are external parasites, living by hematophagy off the blood of rodents. It is the most widely spread of its genus, having originated in Europe, but has been transported to temperate regions all over the world.
Document 7: Mohoidae: Mohoidae is a family of Hawaiian species of recently extinct, nectarivorous songbirds in the genera "Moho" (ʻ ōʻ ō) and "Chaetoptila" (kioea). These now extinct birds form their own family, representing the only complete extinction of an entire avian family in modern times, when the disputed family Turnagridae is disregarded for being invalid.
Document 8: Lord Howe gerygone: The Lord Howe gerygone ("Gerygone insularis)" was a small bird in the family Acanthizidae, brown and greyish in color. Its head was brown apart from a pale grey eye-ring and a grey throat and chin, many parts of the animal varied to the colour of yellow, this being apparent in its bright yellow belly. It made its home in the canopies of the island's forest until the early 20th century. The bird has had a variety of monikers: locally, it was known as the "rain-bird" due to its activity after the rains, or the "pop-goes-the-weasel", due to the similarity of its song to the well-known tune. Another name for this bird is the Lord Howe gerygone flyeater. The bird was endemic to Lord Howe Island in the Tasman Sea (part of New South Wales, Australia). There have been no records of the species since 1928, and it is considered to be extinct. Its extinction is almost certainly due to predation by black rats which were accidentally introduced to the island in 1918 following the shipwreck of the SS "Makambo" there.
Document 9: List of rodents of the Caribbean: The Caribbean region is home to a diverse and largely endemic rodent fauna. This includes the endemic family Capromyidae (hutias), which are largely limited to the Greater Antilles, and two other groups of endemic hystricognaths, the heteropsomyines and giant hutias, including the extinct bear-sized "Amblyrhiza inundata". Lesser Antillean rodent faunas mostly consist of oryzomyines, members of a distantly related group of rodents, and include two of the largest known oryzomyines, "Megalomys desmarestii" and ""Oryzomys hypenemus"". Various other rodents are limited to land-bridge islands such as Trinidad, which were connected to the mainland during glacial-period lowered sea levels in the Pleistocene, or to smaller portions of the Caribbean archipelago. Much of the native rodent fauna of the Caribbean are extinct because of human influences, particularly following the introduction of invasive species such as Old World rats.
Document 10: Jungle crow: The jungle crow ("Corvus macrorhynchos"), is a widespread Asian species of crow. It is very adaptable and is able to survive on a wide range of food sources, making it capable of colonizing new areas, due to which it is often considered a nuisance, especially on islands. It has a large bill which is the source of its scientific name "macrorhynchos" (Ancient Greek for "large beak"), and it is sometimes known by the common names large-billed crow or thick-billed crow. It can also be mistaken for a raven. Johann Georg Wagler first described the species from a holotype obtained from Java in the year 1827.
Document 11: David Boynton: David Boynton (1945–2007) was a leading expert on the natural history of the Hawaiian island of Kauai, especially on the Koke'e Forest and the Alakai Swamp and its wildlife. He was called "a voice for the Hawaiian wilderness," a "Guardian of the Koke'e Forest," and as an educator, "the window through which thousands of Hawai'i students learned about Hawaiian birds, plants, marine creatures, climate and much more." Boynton photographed a bird now believed extinct, the ʻ Ōʻ ōʻ āʻ ā ("Moho braccatus"). He recorded the mating call of the single male, whose mate presumably did not survive Hurricane Iwa at the end of 1982. The bird, probably the last of its species, was tending an empty nest.
Document 12: Biodiversity of New Zealand: The biodiversity of New Zealand, a large island nation located in the southwestern Pacific Ocean, is varied and distinctive accumulated over many millions of years as lineages evolved in the local circumstances. Recently a component has been introduced by humans. New Zealand's pre-human biodiversity exhibited high levels of species endemism, but has experienced episodes of biological turnover. Global extinction approximately 65 Ma ago, resulted in the loss of fauna such as dinosaurs, pterosaurs and marine reptiles e.g. mosasaurs, elasmosaurs and plesiosaurs. The ancient fauna is not well known, but at least one species of terrestrial mammal existed in New Zealand around 19 Ma ago. For at least several Ma before the arrival of human and commensal species, the islands had no terrestrial mammals except for bats and seals, the main component of the terrestrial fauna being insects and birds. New Zealand has developed a national Biodiversity Action Plan to address conservation of considerable numbers of threatened flora and fauna within New Zealand.
Document 13: ʻIʻiwi: The ʻ iʻ iwi ("Drepanis coccinea", pronounced , "ee-EE-vee"), or scarlet honeycreeper is a "hummingbird-niched" species of Hawaiian honeycreeper. It is one of the most plentiful species of this family, many of which are endangered or extinct. The ʻ iʻ iwi is a highly recognizable symbol of Hawaiʻ i. The ʻ iʻ iwi is the third most common native land bird in the Hawaiian Islands. Large colonies of ʻ iʻ iwi inhabit the islands of Hawaiʻ i, Maui, and Kauaʻ i, with smaller colonies on Molokaʻ i and Oʻ ahu but are no longer present on Lānaʻ i. Altogether, the remaining populations total 350,000 individuals, but are decreasing.
Document 14: Moho (genus): Moho is a genus of extinct birds in the Hawaiian bird family, Mohoidae, that were endemic to the Hawaiian Islands. Members of the genus are known as ʻ ōʻ ō in the Hawaiian language. Their plumage was generally striking glossy black; some species had yellowish axillary tufts and other black outer feathers. Most of these species became extinct by habitat loss and by extensive hunting because their plumage were used for the creation of precious "ʻ aʻ ahu aliʻ i" (robes) and "ʻ ahu ʻ ula" (capes) for "aliʻ i" (Hawaiian nobility). The Kauaʻ i ʻ ōʻ ō was the last species of this genus to become extinct, probably a victim of avian malaria.
Document 15: Enderby Island rabbit: The Enderby Island Rabbit, or simply Enderby rabbit or Enderby, is a rare breed of domesticated European rabbit ("Oryctolagus cuniculus"). It originates from rabbits introduced to Enderby Island, an uninhabited subantarctic island in New Zealand’s Auckland Islands group, from Australia in October 1865 to serve as castaway food. Over 130 years the isolated population became a distinctive variety. The rabbits were eventually exterminated for wildlife management reasons from Enderby Island in the early 1990s, but a breeding group of 49 rabbits was rescued by the Rare Breeds Conservation Society of New Zealand in September 1992. As a breed the Enderby Island rabbit is not only rare but also endangered due to the large number of hybrids formed with individuals crossing the Enderby with other domestic rabbit breeds.
