The Niau kingfisher (Todiramphus gertrudae) is a species of bird in the family Alcedinidae. It is endemic to the island of Niau in French Polynesia. Its natural habitats are subtropical or tropical dry forests, plantations and rural gardens. Only 125 individuals remain in the wild. The Niau kingfisher is a multicolored, with bright blue feathers, a dusty orange head, and a bright green back. The entire population of these birds lives in Niau, and without serious intervention, they will likely become extinct. [1]
In new studies published in the journal The Auk (published by the American Ornithologists Union) and the Journal of Wildlife Management, Kesler and his team of researchers have uncovered important information to help ensure the birds' survival and a unique way to attach radio transmitters to the birds to track them."Unfortunately, even with all our work to date, the population is still crashing," Kesler said. "We're seeing some turnover, but each year when we return, there are more empty territories and the population decreases. At this rate, these birds will be gone within our lifetime. [1] "
The introduction of other competitive species (such as Felis catus) into the kingfishers habitat led to their decrease in population because of competition for the same food sources. Removal of the new species would likely result in a recovery of the Kingfisher population, at least in the most populated areas. [2]
Clements has merged this bird with the Mangareva kingfisher.
They mainly eat terrestrial arthropods—beetles, Hymenoptera, and Dictyoptera,—and lizards—skinks and geckos. Their diet also includes decapods. They forage within coconut groves. [3]
Kingfishers are a family, the Alcedinidae, of small to medium-sized, brightly coloured birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species living in the tropical regions of Africa, Asia, and Oceania, but also can be found in Europe and the Americas. They can be found in deep forests near calm ponds and small rivers. The family contains 118 species and is divided into three subfamilies and 19 genera. All kingfishers have large heads, long, sharp, pointed bills, short legs, and stubby tails. Most species have bright plumage with only small differences between the sexes. Most species are tropical in distribution, and a slight majority are found only in forests.
The Tuamotu sandpiper is an endangered member of the large wader family Scolopacidae, that is endemic to the Tuamotu Islands in French Polynesia. It is sometimes placed in the monotypic genus Aechmorhynchus. A native name, apparently in the Tuamotuan language, is kivi-kivi.

The Guam kingfisher, called sihek in Chamorro, is a species of kingfisher from the occupied United States Territory of Guam. It is restricted to a captive breeding program following its extinction in the wild due primarily to predation by the introduced brown tree snake.
The collared kingfisher is a medium-sized kingfisher belonging to the subfamily Halcyoninae, the tree kingfishers. It is also known as the white-collared kingfisher, black-masked kingfisher or mangrove kingfisher. It has a wide range extending from the Red Sea across southern Asia to Polynesia. A number of subspecies and subspecies groups have been split from this species including the Pacific kingfisher, the islet kingfisher, the Torresian kingfisher, the Mariana kingfisher, and the Melanesian kingfisher.

The black-backed dwarf kingfisher, also known as the three-toed kingfisher, is a pocket-sized bird in the family Alcedinidae. It was formerly considered as conspecific with the rufous-backed dwarf kingfisher and together the species complex was known by the English name "oriental dwarf kingfisher".
The Marquesan kingfisher or Marquesas kingfisher is a species of bird in the family Alcedinidae. It is endemic to French Polynesia. It is threatened by habitat loss and predation by introduced species, and is currently classified as Critically endangered, with fewer than 500 individuals left in the wild.

The Hawaiian coot, also known as the ʻ'alae ke'oke'o in Hawaiian, is a bird in the rail family, Rallidae, that is endemic to Hawaiʻi. In Hawaiian, ʻalae is a noun and means mud hen. Kea or its synonym keo is an adjective for white. It is similar to the American coot at 33–40.6 cm (13–16 in) in length and weighing around 700 g. It has black plumage and a prominent white frontal shield. Its natural habitats are freshwater lakes, freshwater marshes, coastal saline lagoons, and water storage areas. The bird was federally listed in October 1970 as an endangered species and is considered both endemic and endangered by the state of Hawaii. It is threatened by habitat loss and introduced predators such as the small Asian mongoose. The Makalawena Marsh on the Big Island of Hawaiʻi has been listed as a National Natural Landmark to preserve one of its last nesting areas.
The Tahiti monarch, or Tahiti flycatcher, is a rare species of bird in the monarch flycatcher family. It is endemic to Tahiti in French Polynesia. There are between 25 and 100 individuals remaining with an increasing population trend. Adults boast a striking black plumage with pale blue pills and feet. Recognized for its melodious flute-like song and distinctive "tick-tick-tick" call, it thrives in dense forest, primarily inhabiting canopy and understory amidst native mara trees. Despite facing threats from introduces predators such as ship rats and invasive bird species, conservation efforts have been implemented to safeguard its population.

The subfamily appears to have arisen in Indochina and Maritime Southeast Asia and then spread to many areas around the world. Tree kingfishers are widespread through Asia and Australasia, but also appear in Africa and the islands of the Pacific and Indian Oceans, using a range of habitats from tropical rainforest to open woodlands.
