The Auckland snipe (Coenocorypha aucklandica aucklandica), also known as the Auckland Island snipe, 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 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 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 / Motu Ihupuku. 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.

<span class="mw-page-title-main">Austral snipe</span> 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.

The Campbell snipe, also known as the 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.

<i>Plantago aucklandica</i> Species of flowering plant in the plantain family Plantaginaceae

Plantago aucklandica is a species of flowering plant in the family Plantaginaceae that is endemic to the subantarctic Auckland Islands, New Zealand. Joseph Dalton Hooker described P. aucklandica in his Flora Antarctica in 1844. Plants of this plantain are large with large leaves, up to seven veins, wide petioles, colliculate seeds, and long spikes with dozens of flowers and one-seeded fruits. This species in considered to be At Risk - Naturally Uncommon, as it is an island endemic with a restricted range.

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.
