The Mariana mallard or Oustalet's duck is an extinct species of duck of the genus Anas that was endemic to the Mariana Islands. Its taxonomic status is debated, and it has variously been treated as a full species, a subspecies of the mallard or of the Pacific black duck, or sometimes as a subspecies of the Indian spot-billed duck.
The Guam rail is a species of flightless bird in the Rallidae family, endemic to the United States territory of Guam. It is known locally as the Ko'ko' bird. It was extirpated from the entire island by the late 1980s owing to the predation of the Brown tree snake, an invasive species not native to the island.
The brown tree snake, also known as the brown catsnake, is an arboreal rear-fanged colubrid snake native to eastern and northern coastal Australia, eastern Indonesia, Papua New Guinea, and many islands in northwestern Melanesia. The snake is slender, in order to facilitate climbing, and can reach up to 2 meters in length. Its coloration may also vary, some being brown, green, or even red. Brown tree snakes prey on many things, ranging from invertebrates to birds, and even some smaller mammals. It is one of the very few colubrids found in Australia, where elapids are more common. Due to an accidental introduction after the events of World War II, this snake is now infamous for being an invasive species responsible for extirpating the majority of the native bird population in Guam. Currently, efforts are being made to reduce and control the population on Guam and prevent the snake from spreading to other locations.
The Guam flying fox, also known as the little Marianas fruit bat, was a small megabat from Guam in the Marianas Islands in Micronesia that was confirmed extinct due to hunting or habitat changes. It was first recorded in 1931 and was observed roosting with the larger and much more common Mariana fruit bat. The last specimen was a female found roosting at Tarague cliff in March 1967, but it escaped capture. An unconfirmed sighting took place sometime during the 1970s, and no other individuals have been sighted since then.
The warbling white-eye, also known as the Japanese white-eye and mountain white-eye, is a small passerine bird in the white-eye family. The specific epithet is occasionally written japonica, but this is incorrect due to the gender of the genus. Its native range includes much of East Asia, including the Russian Far East, Japan, Indonesia, Korea, and the Philippines. It has been intentionally introduced to other parts of the world as a pet and as pest control, with mixed results. As one of the native species of the Japanese islands, it has been depicted in Japanese art on numerous occasions, and historically was kept as a cage bird.

The golden white-eye is a species of bird in the white-eye family, Zosteropidae. It is the only species within the genus Cleptornis. The golden white-eye was once considered to be a honeyeater in the family Meliphagidae and although it is now known to be a white-eye, its position within that family is still uncertain. The species is restricted to the islands of Saipan and Aguijan in the Northern Mariana Islands, where it is sympatric and competes with the related bridled white-eye. The golden white-eye has golden plumage and a pale eye-ring. It feeds on insects, fruit, and nectar and forages in pairs or small family groups. The bird is monogamous and lays two eggs in a small cup nest.
