The night parrot (Pezoporus occidentalis) is a small parrot endemic to the continent of Australia. It is well known as being one of the most elusive and mysterious birds in the world, with no confirmed sightings of the bird between 1912 and 1979, leading to speculation that it was extinct. Sightings since 1979 have been extremely rare and the bird's population size is unknown, though based on the paucity of records it is thought to number between 50 and 249 mature individuals. The first photographic and video evidence of a live individual was publicly confirmed in July 2013. After seventeen thousand hours in the field over 15 years of searching, wildlife photographer John Young captured several photos and a 17-second video of the bird in western Queensland. In August 2015, the tagging and tracking of a live individual was announced on Australian media. Other live individuals were photographed in Queensland in late 2016, and sightings recorded in Western Australia and South Australia in 2017. A young bird, likely hatched in late 2017 was recorded in February 2018.
Ornithologist John Gould described the night parrot in 1861, from a specimen—the holotype—that was collected 13 km southeast of Mt Farmer, west of Lake Austin in Western Australia. Its specific epithet is Latin occidentalis "western". The species was originally placed within its own genus (Geopsittacus) by Gould, though consensus soon swung in favour of placing it in Pezoporus; James Murie dissected a specimen, observing that it was very similar in anatomy and plumage to the ground parrot. Gould had posited a relationship to the kakapo based on similarity of the plumage, however Murie concluded they were markedly different anatomically. Despite its close relationship with the ground parrot, its placement in the genus Pezoporus was uncertain, with some authorities leaving it in its own genus, as data on the night parrot was so limited. A 1994 molecular study using the cytochrome b of several parrot species confirmed the close relationship of the taxa and consensus for its placement in Pezoporus. It also revealed that the kakapo was not closely related to Pezoporus. Analysis of mitochondrial and nuclear DNA sequences in a 2011 study showed that the night parrot most likely diverged from the ancestor of the eastern and western ground parrots around 3.3 million years ago.
A relatively small and short-tailed parrot, the species' colour is predominantly a yellowish green, mottled with dark brown, blacks and yellows. Both sexes have this coloration. It is distinguished from the two superficially similar ground parrot species by its shorter tail and different range and habitat. Predominantly terrestrial, taking to the air only when panicked or in search of water, the night parrot has furtive, nocturnal habits and—even when it was abundant—was apparently a highly secretive species. Its natural habitat appears to be the spinifex grass which still dominates much of the dry, dusty Australian interior; other early reports also indicate that it never strayed far from water. It may also inhabit chenopod shrublands, eucalyptus woodlands, and mallee shrublands. One of the vocalisations of the night parrot has been described as a croak and identified as a contact call. Other calls, mostly short 'ding-ding' whistles, and a more drawn out whistle, have been recorded from Queensland and Western Australia.
Historic sources indicate that night parrot eats seeds of grasses (especially Triodia) and herbs.
The population size of this species is not known, but assumed to be continuing to decline. As of 2012, it is listed on the IUCN Red List as Endangered, having previously been listed as Critically Endangered. According to the IUCN Red List the night parrot has a population of 50–249 or possibly larger. It is listed as Endangered under the Environment Protection and Biodiversity Conservation Act 1999 by the Australian government.
The night parrot remains one of the most elusive and mysterious birds in the world of ornithology. Reliable records of the bird have been few and far between, with efforts to locate the species proving fruitless after an authenticated report from 1912. Ornithologists continued to patrol the outback for traces, even checking the old nests of other birds, such as the zebra finch, for fragments of night parrot feathers.
In 1979, ornithologist Shane Parker from the South Australian Museum spotted an apparent flock of the birds in the far north of South Australia. A roadkill specimen was discovered in 1990 by scientists returning from an expedition in a remote part of Queensland, and three individuals were seen in 2005 near Minga Well, in the Pilbara region of Western Australia.
Recent sightings of the bird:
- April 2005, Pilbara region of Western Australia and near the Fortescue Marshes.
- September 2006, dead female, Diamantina National Park.
- May 2013, first photograph and video footage of a living specimen and discovery of the first known resident population of the species. Subsequent DNA testing of feathers found confirms the find.
- 2016, Young announced he had found night parrots in Diamantina National Park, adjacent to the Pullen Pullen nature reserve. Seven sightings were recorded, including a pair and three active nests with eggs.
- September 2016, a camera trap recorded what appears to be a night parrot near Lake Eyre in South Australia; while the following July a single night parrot feather was found in a finch nest at Kalamurina Station in the northern Lake Eyre region.
- January 2017, whistle call attributed to night parrot recorded in southern Northern Territory
- March 2017, photograph of a living specimen in Western Australia.
- February 2018, the image of a young bird, aged 3 to 5 months old, was recorded by a researcher.
The approval of the A$2 billion Cloud Break mine project through the then-Minister for the Environment, Ian Campbell, was criticised because of a number of endangered species in the area of the future mine, among them the night parrot. In order to gain EPA approval, the mine had to implement a management plan to ensure that mining activities would not have a negative effect on the species survival in the area. The occurrence of the night parrot in the future mining area, at Minga Well on 12 April 2005, was discovered during a 2005 survey commissioned by FMG, which was carried out by two contract biologists who sighted a small group of the birds. Unconfirmed sightings of the bird had been made previously in a nearby area in 2004.
The sighting, at dusk, was by biologists Dr Robert Davis and Mr Brendan Metcalf, who were not able to obtain a photograph of the three birds they saw, but are confident that they spotted three night parrots. The detailed descriptions of their sighting were accepted by the Birds Australia Rarities Committee (BARC) making it the first accepted night parrot sighting in modern times. Based on this acceptance by scientific peers, a paper describing the sighting was published in the Australian ornithological journal, Emu in 2008. The two biologists carried out further searches at Minga Well and Moojari Well the following five nights after the sighting, but were unable to see the birds again. A follow up survey of the Fortescue Marsh area in May 2005 was unsuccessful in finding any conclusive evidence of the species.
In May 2013 wildlife cinematographer John Young, who made headlines in 2006 with an allegedly fake photo series of the blue-fronted fig parrot, had the opportunity to make the first ever photographs and video footage of a living specimen. He revealed his results during an invitation-only press conference on 3 July 2013, but kept the exact range in Queensland where he had observed this individual secret to protect this species from poaching. Young provided five feathers from a roost site in the Lake Eyre basin to the Western Australian Museum's Molecular Systematics Unit, where DNA analysis conclusively matched the feathers to DNA samples of dead Pezoporus occidentalis birds. Young declared that this was conclusive in establishing that the bird in his photographs and video is a night parrot. In October 2018, Australian Wildlife Conservancy (AWC) commenced an investigation into claims that some of John Young's first photographs of the Night Parrot may have been staged. 
Capture of live individual
On 4 April 2015, ornithologist Steve Murphy and partner Rachel Barr captured and radio tagged a live individual, whom they nicknamed "Pedro", in southwestern Queensland. Photographs of the bird in Murphy's hand were released to Australian media on 10 August 2015, while keeping the precise location secret. A conservation reserve covering some 56,000 hectares has been created in the area to protect the species.
Sean Dooley of Birdlife Magazine described the find as, "The bird watching equivalent of finding Elvis flipping burgers in an outback roadhouse." South Australian Museum collection manager Philippa Horton called the find, "One of the holy grails, one of the world's rarest species probably".
