The Auckland Island snipe (Coenocorypha aucklandica aucklandica) is a small bird in the sandpiper family. It is the isolated nominate subspecies of the subantarctic snipe that is endemic to the Auckland Islands, a subantarctic island group south of New Zealand in the Southern Ocean.

Taxonomy and etymology

The Auckland Island snipe was first collected in 1840 both by Charles WilkesUnited States Exploring Expedition, and James RossErebus and Terror Antarctic expedition, with the British specimens forming the basis for George Gray's 1844 description. [1] The species name, and hence the subspecific epithet, refer to the type locality.

Description

The subspecies is generally similar to others in the genus, being a small, brown, cryptically patterned snipe with a long bill, short neck, tail and legs, and short, rounded wings. Females are slightly larger than males, weighing about 107 g compared with the males’ 82–94 g. [2]

Distribution and habitat

The snipe is endemic to the Auckland Islands, which has a total surface area of 625 km2. However, it is no longer present on main Auckland Island, but only on 100 km2 Adams Island, Enderby Island, and the much smaller Disappointment, Ewing, Figure of Eight, Rose, Ocean and Dundas Islands. [2] It inhabits the islands’ tussock grasslands, Olearia forest, shrubland and herbfields. [2]

Breeding

Breeding is seasonal, with a records of egg-laying from late September to early November with chicks present in November–December. The typical clutch size is two. [2] Hakawai” aerial displays have been recorded. [3]

Status and conservation

The population of the snipe is estimated at 20,000 birds. [4] It has been classified as a range-restricted island endemic with a stable population. [5]

The Auckland Islands are an archipelago of New Zealand, lying 465 kilometres (290 mi) south of the South Island. The main Auckland Island, occupying 510 km2 (200 sq mi), is surrounded by smaller Adams Island, Enderby Island, Disappointment Island, Ewing Island, Rose Island, Dundas Island, and Green Island, with a combined area of 626 km2 (240 sq mi). The islands have no permanent human inhabitants.

Bushwren Species of extinct bird

The bushwren, bush wren, or mātuhituhi in Māori, was a very small and almost flightless bird that was endemic to New Zealand. It had three subspecies on each of the major islands of New Zealand, the North Island, South Island, and Stewart Island and nearby smaller islands. The species disappeared gradually after the introduction of invasive mammalian predators, last being seen on the North Island in 1955 and the South Island in 1968. Attempts were made to save the remaining population on small islands off Stewart Island, but they ultimately failed with the death of the last remaining known birds in 1972.

Campbell Island, New Zealand Island in New Zealand

Campbell Island / Motu Ihupuku is an uninhabited subantarctic island of New Zealand, and the main island of the Campbell Island group. It covers 112.68 square kilometres (43.51 sq mi) of the group's 113.31 km2 (43.75 sq mi), and is surrounded by numerous stacks, rocks and islets like Dent Island, Folly Island, Isle de Jeanette-Marie, and Jacquemart Island, the latter being the southernmost extremity of New Zealand. The island is mountainous, rising to over 500 metres (1,640 ft) in the south. A long fjord, Perseverance Harbour, nearly bisects it, opening out to sea on the east coast.

Tūī Species of bird

The tūī is a boisterous medium-sized bird native to New Zealand. It is blue, green, and bronze colored with a distinctive white throat tuft. It is an endemic passerine bird of New Zealand, and the only species in the genus Prosthemadera. It is one of the largest species in the diverse Australasian honeyeater family Meliphagidae, and one of two living species of that family found in New Zealand, the other being the New Zealand bellbird. The tūī has a wide distribution in the archipelago, ranging from the subtropical Kermadec Islands to the sub-Antarctic Auckland Islands, as well as the main islands.

Subantarctic snipe Species of bird

The Subantarctic snipe is a species of snipe endemic to New Zealand's subantarctic islands. The Maori call it "Tutukiwi". The nominate race C. a. aucklandica is found on the Auckland Islands. Other subspecies include C. a. meinertzhagenae from the Antipodes Islands, and C. a. perseverance from Campbell Island. The former subspecies from the Snares Islands has been separated as a full species, the Snares snipe, as have the extinct South Island and North Island snipes.

Austral snipe Genus of birds

The austral snipes, also known as the New Zealand snipes or tutukiwi, are a genus, Coenocorypha, of tiny birds in the sandpiper family, which are now only found on New Zealand's outlying islands. There are currently three living species and six known extinct species, with the Subantarctic snipe having three subspecies, including the Campbell Island snipe discovered as recently as 1997. The genus was once distributed from Fiji, New Caledonia and Norfolk Island, across New Zealand and southwards into New Zealand's subantarctic islands, but predation by introduced species, especially rats, has drastically reduced their range.

Hakawai (mythology)

Hakawai, also Hokioi in the North Island, was to the New Zealand Māori people, a mythological bird that was sometimes heard but not usually seen. It is now associated with the nocturnal aerial displays made by Coenocorypha snipe.

Campbell snipe Subspecies of bird

The Campbell snipe or Campbell Island snipe is a rare subspecies of the Subantarctic snipe, endemic to Campbell Island, a subantarctic island south of New Zealand in the Southern Ocean. It was not formally described until January 2010. The subspecific name alludes to the name of the sealing brig Perseverance, captained by Frederick Hasselborough, that discovered Campbell Island in 1810, and which probably inadvertently introduced rats to the island when it was wrecked there in 1828.

Megaherb

Megaherbs are a group of herbaceous wildflowers growing in the New Zealand subantarctic islands and on the other subantarctic islands. They are characterised by their great size, with huge leaves and very large and often unusually coloured flowers, which have evolved as an adaptation to the harsh weather conditions on the islands. They suffer from overgrazing due to introduced mammals.
