bird
Snowy sheathbill, Grytviken..
Sheathbills' diet is similar to that of skuas. Their flight is a bit clumsy, but they are mostly migratory, breeding from South Georgia south and wintering in South America and the Falklands. They are related to plovers and, unlike other seabirds, don't have webbed feet. This species only breeds in Scotia Sea area, with total population estimated at 10,000 pairs. Most of them hang out around penguin colonies in summer, and garbage dumps in winter. They are very tame.

The sheathbills are a family of birds, Chionidae. Classified in the wader order Charadriiformes, the family contains one genus, Chionis, with only two species. They breed on subantarctic islands and the Antarctic Peninsula, and the Snowy Sheathbill, Chionis alba, migrates to the Falkland Islands and coastal southern South America in the
southern winter; they are the only bird family endemic as breeders to the Antarctic region. They are also the only Antarctic birds without webbed feet.

The other specimen is the Black-faced Sheathbill, Chionis minor, also known as the Lesser Sheathbill or
Paddy bird, is an aberrant shorebird which are terrestrial scavenger of subantarctic islands.

Restricted to subantarctic islands in the southern Indian Ocean: the South African territory of the Prince Edward Islands, the French territories of the Crozet Islands and Kerguelen Islands, and the Australian territory of Heard Island. The race Chionis minor nasicornis is endemic to Heard Island, while the race Chionis minor marionesis
is endemic to the Prince Edward Islands.

Blue-eyed shags inhabit rocky cliffs on all island groups around the Scotia Sea. Recent DNA research suggested that three very similar races are,
in fact, separate species: Imperial shag, Phalacrocorax atriceps, in South America and the Falklands, South Georgian Shag, Phalacrocorax georgianus, on South Georgia, South Orkney and South Sandwich Islands, and Antarctic shag, Phalacrocorax bransfieldensis, on South Shetlands
and the Peninsula.
Three more species of cormorants occur on Tierra del Fuego. All are mostly sedentary, and hunt for fish not far from shore, sometimes in large flocks.

The Imperial Shag
, Phalacrocorax atriceps, is a black and white cormorant native to many subantarctic islands, the Antarctic Peninsula and southern South America, primarily in rocky coastal regions, but locally also at large inland lakes. It is sometimes placed in the genus Leucocarbo instead. It is also known as the Blue-eyed Shag, Blue-eyed Cormorant and by many other names, and is one of a larger group of cormorants called blue-eyed shags.
The taxonomy is very complex, and several subspecies are often considered separate species instead.

The Imperial Shag has a total length of 70–78 cm (28–31 in) and weighs 1.8-3.5 kg (4-8 lbs), with males averaging larger than females.[3] It is endowed with glossy black feathers covering most of its body, with a white belly and neck. It possesses a distinctive ring of blue skin around its eyes, an orange-yellow nasal knob, pinkish legs and feet, and an erectile black crest.[7] During the non-breeding season, adults lack the crest, have a duller facial area, and less/no white to the back/wings.

The Red-legged Cormorant, Phalacrocorax gaimardi, also known as the Red-legged Shag, Red-footed Cormorant, Red-footed Shag, Gaimard’s Cormorant and Grey Cormorant, is a resident of the coastline of
South America. It is non-colonial unlike most seabirds.

The Red-legged Cormorant has not been observed wing-spreading, which is characteristic of most cormorant species. It is considered near threatened under the IUCN Red List of Threatened Species.

The Red-legged Cormorant is a medium sized seabird, with a long neck, streamlined body, webbed feet and a long, thin hooked bill. Its body length is 71–76 centimetres (28–30 in), with an average wingspan of 91 cm (36 in).[4]
It weighs 1.3–1.5 kilograms (2.9–3.3 lb).[2] There is no sexual dimorphism between the male and female

bird
Flying steamerduck, Ushuaia,
Tierra del Fuego..
Steamerducks are so called because their often run across water surface, flapping their wings as an old steamer boat with sidewheels. The widespread flying species, Tachyeres patachonicus, is apparently the ancestor of flightless Magellanic steamerduck, Tachyeres pteneres, on Tierra del Fuego, and Falkland steamerduck, Tachyeres brachypterus, on the Falklands.

The Kelp Goose
(Spanish: Caranca or Cauquén Marino), Chloephaga hybrida, is a member of the duck, goose and swan family Anatidae. It is in the shelduck subfamily Tadorninae. It can be found in the Southern part of South America; in Patagonia, Tierra del Fuego, and the Falkland Islands.
Kelp geese inhabit areas of southern Chile and Argentina, mainly in Patagonia, Tierra del Fuego, and the Falkland Islands. They habitat rocky coasts around their food sources.

Males are a white color, with a black beak, and yellow feet. The females are dark brown, with
transverse gray lines on the chest, and yellow feet.

Kelp geese generally have clutches of 2-7 eggs. They prefer to hide their eggs in long grass.
The eggs hatch about a month later.

There are about 15,000 breeding pairs in existence. Kelp geese are noted for only eating kelp and
will migrate along the coast of South America in order to find kelp, hence the name 'kelp geese'.

The Black-necked Swan, Cygnus melancoryphus, is the largest waterfowl native to South America.
Males are 115 to 140 cm (45 to 55 in) and weigh 4.5-6.7 kg (10-14.8 lbs); females are 100 to 124 cm
(39 to 49 in) and weigh 3.5-4.4 kg (7.7–9.7 lbs). The wingspan ranges from 135 to 177 cm (53 to 70 in).
The body plumage is white with a black neck, head and greyish bill. It has a red knob near the base of the bill
and white stripe behind eye. The sexes are similar, with the female slightly smaller. The cygnet has a light grey plumage with black bill and feet. The Black-necked Swan was formerly placed in monotypic genus, Sthenelides.

The smallest member in its genus, it is found in freshwater marshes, lagoon and lake shores in southern South America. The Black-necked Swan breeds in Chilean Southern Zone, Patagonia, Tierra del Fuego and on the Falkland Islands. In the austral winter, this species migrates northwards to Paraguay and southern Brazil
The wetlands created by the Great Chilean Earthquake like Carlos Anwandter Nature Sanctuary in Cruces River have become important population centers for the Black-necked Swan.

The Crested Duck
, Lophonetta specularioides, is a species of duck native to South America, the only member of the monotypic genus Lophonetta. It is sometimes included in Anas.

There are two subspecies: Andean Crested Duck, Lophonetta specularioides alticola and Patagonian Crested Duck, Lophonetta specularioides specularioides. The Patagonian Crested Duck is also called the Southern Crested Duck and its range lies in the Falklands, Chile, and Argentina.

It feeds on invertebrates and algae, and prefers shallow coastal regions. It nests in tall grass near water
and lays 5 to 7 eggs.

The Black-crowned Night Heron
, Nycticorax nycticorax, commonly abbreviated to just Night Heron in Eurasia, is a medium-sized heron found throughout a large part of the world, except in the coldest regions and Australasia (where replaced by the closely related Rufous Night Heron, with which it has hybridized in the area of contact).

Adults are approximately 64 cm (25 in) long and weigh 800 g (28 oz). They have a black crown and back with the remainder of the body white or grey, red eyes, and short yellow legs. They have pale grey wings and white underparts

The Upland Goose or Magellan Goose, Chloephaga picta, is a South American member of the duck, goose and swan family Anatidae. It is in the shelduck subfamily, Tadorninae. Males have a white head and breast, whereas
the females are brown with black-striped wings and yellow feet, and could be mistaken for Ruddy-headed Geese. These birds are 60–72.5 centimetres (24–28.5 in) long and weigh 2.7–3.2 kilograms (6.0–7.1 lb).[2]
They are found in open grasslands.

Upland Geese are noted in Chapter VI of The Origin of Species for having vestigial webbing between their toes.

Correndera pipit
Anthus correndera,
Stanley, Falkland Islands.

Unfortunately, the only native land mammal, Falkland Islands fox (D. australis), has been exterminated in the 19th century. Introduced mammals include Patagonian foxes, feral cats, rabbits, rats, mice, and, on one small island, guanaco. Numerous marine mammals inhabit surrounding waters. Of about 70 breeding bird species, two - Cobb's wren (above) and Falkland steamerduck are endemic; two more are very rare on the mainland. There are also many endemic bird subspecies, four unique freshwater fishes, and at least twelve endemic plants.

The Striated Caracara, Phalcoboenus australis


The Striated Caracara, Phalcoboenus australis, is a bird of prey of the Falconidae family.
The adults' plumage is almost black in colour, while the legs and lores are orange and the neck is flecked with grey.
The first year juveniles have an orange or light red down, which they lose after their first molt. Full adult plumage is
acquired only in the fifth year.

It breeds in several islands in Tierra del Fuego, but is more abundant in the Falklands. Though it was once considered
common in the Falklands archipelago, it now only nests in the outlying islands where it breeds around penguin and
albatross colonies.

The Striated Caracara is primarily a scavenger, feeding on carrion, offal and small invertebrates that it digs up with its claws. However it will also prey on weak or injured creatures, such as young seabirds. Its habit of attacking newborn lambs and
weakened sheep has led it to be ruthlessly persecuted by sheep farmers.

Often it is known to steal red objects such as clothing or handkerchiefs, possibly because red is the colour of meat.
Like all falconiformes it has excellent colour vision which easily surpasses that of any known mammal. Often it will
also raid dustbins and move rocks to get food from underneath, thus proving themselves to be one of the most
intelligent of the birds of prey.

Striated Caracara, Phalcoboenus australis

The nest is built on the ground or on a cliff ledge, where the female will lay up to 4 eggs. Their hatching is timed to coincide
with the nesting season of seabirds, providing a constant food supply for the chicks. Once these have fledged, they gather
into flocks and roam through the islands, often close to human settlements.

The population in the Falklands is estimated at 500 breeding pairs. Juveniles and indeed, adults, are almost entirely
fearless of humans and treat their approach with indifference. Over time, conflict with the sheep farmers has led to a
great reduction in their numbers. This is now being corrected by the Falkland Islanders.
