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.
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]
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]
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.
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.
Richard's pipit is a medium-sized passerine bird which breeds in open grasslands in the East Palearctic. It is a long-distance migrant moving to open lowlands in the Indian subcontinent and Southeast Asia. It is a rare but regular vagrant to western Europe.
The red-throated pipit is a small passerine bird, which breeds in the far north of Europe and the Palearctic, with a foothold in northern Alaska. It is a long-distance migrant, moving in winter to Africa, South and East Asia and the West Coast United States. It is a vagrant to Western Europe.
The tree pipit is a small passerine bird which breeds across most of Europe and the Palearctic as far East as the East Siberian Mountains. It is a long-distance migrant moving in winter to Africa and southern Asia. The scientific name is from Latin: anthus is the name for a small bird of grasslands, and the specific trivialis means "common".
The buff-bellied pipit or American pipit is a small songbird found on both sides of the northern Pacific. It was first described by Marmaduke Tunstall in his 1771 Ornithologia Britannica. It was formerly classified as a form of the water pipit. It is known as "American pipit" in North America and "buff-bellied pipit" in Eurasia.
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.
The plain-backed pipit or plain pipit is a medium-sized passerine bird which is a resident breeder in Africa south of the Sahara Desert.
Sharpe's longclaw is a passerine bird in the longclaw family Motacillidae, which also includes the pipits and wagtails. It is endemic to Kenya.
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.
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.
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.
The Nilgiri pipit is a distinctive species of pipit that is endemic to the high altitude hills of southern India. Richer brown in colour than other pipits in the region, it is distinctive in having the streaking on the breast continuing along the flanks. It is non-migratory and has a tendency to fly into low trees when disturbed and is closely related to the tree pipits Anthus hodgsoni and Anthus trivialis.
Schlieper Bay is a bay 1 mile (1.6 km) wide, entered between Romerof Head and Weddell Point along the south coast of South Georgia. It is separated from Church Bay by the Scree Gap. Schlieper Bay was named between 1905 and 1912 after the director of the Compañía Argentina de Pesca.
The New Zealand pipit is a fairly small passerine bird of open country in New Zealand and outlying islands. It belongs to the pipit genus Anthus in the family Motacillidae.
The Henderson petrel is a ground-nesting species of gadfly petrel in the family Procellariidae. Adults measure on average 37 cm. It has a uniform grey-brown plumage.
The yellow tufted pipit or African rock pipit is a small-sized, passerine bird that is native to South Africa and Lesotho. The yellow tufted pipit is commonly found in mountain terrain, and they create their habitats in high-altitude shrub-land, grassland, and rocky areas. The yellow tufted pipit is identified by its brown and gray feathers. The bird has a white-gray eyebrow and yellow markings within its wings and stomach. The call of the yellow tufted pipit allows the bird to stand out from other pipit species. The bird produces a repeated “whee-tsrreeu” that is loud and high-pitched. The yellow tufted pipit has a life expectancy ranging from two to three years old.
Hellmayr's pipit is a species of bird in the family Motacillidae. It is found in Argentina, Bolivia, Brazil, Chile, Paraguay, Peru, and Uruguay. Its natural habitats are temperate grassland, subtropical or tropical high-altitude grassland, and pastureland.
The buffy pipit is a species of bird in the Motacillidae family. It is found in plains and open countryside in southern and eastern Africa. The IUCN has assessed its conservation status as being of least concern.
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.
