The South Georgia pipit (Anthus antarcticus) is a sparrow-sized bird only found on the South Georgia archipelago off the Antarctic Peninsula. It is the only songbird in Antarctica, South Georgia's only passerine, and one of the few non-seabirds of the region.

Contents

It builds nests from dried grass, usually within tussac grass, and lays four eggs a year. It feeds on small insects and spiders, and beach debris.

It has been threatened by the human introduction of rats, and also by environmental damage caused by humans. It has been chosen as the poster bird of the South Georgia Heritage Trust's Habitat Restoration (Rat Eradication) project, which started eradicating rats on South Georgia in 2011. The project's baiting phase ended in early 2015, and success was confirmed in 2018. [2] [3]

In 2004 the population was estimated to be 6000 to 8000 mature individuals. [4] Prior to the restoration it was rare to see South Georgia pipits, most often on the rat-free Prion Island. Afterwards their numbers have increased noticeably and are much more often seen by visitors. [5]

Description

The South Georgia pipit is a small and stocky pipit, 17 cm (6.7 in) long and weighing 36 g (1.3 oz). The species has long legs and a long hindclaw and a short tail. [6]

<span class="mw-page-title-main">Pipit</span> Genus of birds

The pipits are a cosmopolitan genus, Anthus, of small passerine birds with medium to long tails. Along with the wagtails and longclaws, the pipits make up the family Motacillidae. The genus is widespread, occurring across most of the world, except the driest deserts, rainforest and the mainland of Antarctica.

<span class="mw-page-title-main">Motacillidae</span> Family of birds

The wagtails, longclaws, and pipits are a family, Motacillidae, of small passerine birds with medium to long tails. Around 70 species occur in five genera. The longclaws are entirely restricted to the Afrotropics, and the wagtails are predominantly found in Europe, Africa, and Asia, with two species migrating and breeding in Alaska. The pipits have the most cosmopolitan distribution, being found mostly in the Old World, but occurring also in the Americas and oceanic islands such as New Zealand and the Falklands. Two African species, the yellow-breasted pipit and Sharpe's longclaw, are sometimes placed in a separate seventh genus, Hemimacronyx, which is closely related to the longclaws.

The olive-backed pipit is a small passerine bird of the pipit (Anthus) genus, which breeds across southern, north central and eastern Asia, as well as in the north-eastern European Russia. It is a long-distance migrant moving in winter to southern Asia and Indonesia. Sometimes it is also called Indian pipit or Hodgson's pipit, as well as tree pipit owing to its resemblance with the tree pipit. However, its back is more olive-toned and less streaked than that species, and its head pattern is different with a better-marked supercilium.

The paddyfield pipit or Oriental pipit is a small passerine bird in the pipit and wagtail family. It is a resident (non-migratory) breeder in open scrub, grassland and cultivation in southern Asia east to the Philippines. Although among the few breeding pipits in the Asian region, identification becomes difficult in winter when several other species migrate into the region. The taxonomy of the species is complex and has undergone considerable changes.

<span class="mw-page-title-main">Island restoration</span>

The ecological restoration of islands, or island restoration, is the application of the principles of ecological restoration to islands and island groups. Islands, due to their isolation, are home to many of the world's endemic species, as well as important breeding grounds for seabirds and some marine mammals. Their ecosystems are also very vulnerable to human disturbance and particularly to introduced species, due to their small size. Island groups, such as New Zealand and Hawaii, have undergone substantial extinctions and losses of habitat. Since the 1950s several organisations and government agencies around the world have worked to restore islands to their original states; New Zealand has used them to hold natural populations of species that would otherwise be unable to survive in the wild. The principal components of island restoration are the removal of introduced species and the reintroduction of native species.

<span class="mw-page-title-main">Campbell teal</span> Species of bird

The Campbell teal or Campbell Island teal is a small, flightless, nocturnal species of dabbling duck of the genus Anas endemic to the Campbell Island group of New Zealand. It is sometimes considered conspecific with the brown teal. The plumage is similar to that of the Auckland teal, dark sepia with the head and back tinged with green iridescence, and a chestnut breast on the male, with the female dark brown all over. Its natural habitat is tussock grassland dominated by Poa tussock grass, ferns and megaherbs. The species also uses the burrows and pathways of petrel species that nest on the islands. They are apparently territorial in the wild, and probably feed on amphipods and insects. The IUCN classifies it as vulnerable.

<span class="mw-page-title-main">Sprague's pipit</span> Species of bird

Sprague's pipit is a small songbird (passerine) in the family Motacillidae that breeds in the short- and mixed-grass prairies of North America. Migratory, it spends the winters in the southwestern United States and northern Mexico. Sprague's pipits are unusual among songbirds in that they sing high in the sky, somewhat like a goldfinch or skylark. It is more often identified by its distinctive descending song heard from above than by being seen on the ground. Males and females are cryptically coloured and similar in appearance; they are a buffy brown with darker streaking, slender bills and pinkish to yellow legs. Sprague's pipit summer habitat is primarily native grasslands in the north central prairies of the United States and Canada. The species was named after the botanical illustrator Isaac Sprague.

<span class="mw-page-title-main">Introduced mammals on seabird breeding islands</span>

Seabirds include some of the most threatened taxa anywhere in the world. For example, of extant albatross species, 82% are listed as threatened, endangered, or critically endangered by the International Union for Conservation of Nature. The two leading threats to seabirds are accidental bycatch by commercial fishing operations and introduced mammals on their breeding islands. Mammals are typically brought to remote islands by humans either accidentally as stowaways on ships, or deliberately for hunting, ranching, or biological control of previously introduced species. Introduced mammals have a multitude of negative effects on seabirds including direct and indirect effects. Direct effects include predation and disruption of breeding activities, and indirect effects include habitat transformation due to overgrazing and major shifts in nutrient cycling due to a halting of nutrient subsidies from seabird excrement. There are other invasive species on islands that wreak havoc on native bird populations, but mammals are by far the most commonly introduced species to islands and the most detrimental to breeding seabirds. Despite efforts to remove introduced mammals from these remote islands, invasive mammals are still present on roughly 80% of islands worldwide.
