Bertha's Beach Important Bird Area
Bertha's Beach Important Bird Area comprises 3300 ha of coastal wetlands at the entrance to Choiseul Sound, on the east coast of East Falkland, in the Falkland Islands. It lies about 8 km south-east of Mount Pleasant Airport and 40 km south-west of Stanley. It has been identified by BirdLife International as an Important Bird Area (IBA) because of its significancer for a variety of migratory waders and other waterbirds. Overlapping it is the 4000 ha Bertha's Beach Ramsar site, recognising it as a wetland of international importance. Description The site comprises the coast and its immediate hinterland from Fox Point to Bertha's Beach. It contains typical Falkland coastal wetland habitat with a white sand beach, coastal dunes, maritime heathland, freshwater ponds and brackish lagoons. The land behind Bertha's Beach is dominated by white grass plains. To the north-east of Bertha's Beach is a large area of coastal lowlands with islands and promontories, w ...

Ramsar Convention
The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of Ramsar sites (wetlands). It is also known as the Convention on Wetlands. It is named after the city of Ramsar in Iran, where the convention was signed in 1971. Every three years, representatives of the contracting parties meet as the Conference of the Contracting Parties (COP), the policy-making organ of the convention which adopts decisions (resolutions and recommendations) to administer the work of the convention and improve the way in which the parties are able to implement its objectives. COP12 was held in Punta del Este, Uruguay, in 2015. COP13 was held in Dubai, United Arab Emirates, in October 2018. List of wetlands of international importance The list of wetlands of international importance included 2,331 Ramsar sites in May 2018 covering over . The countries with most sites are the United Kingdo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peale's Dolphin
Peale's dolphin (''Lagenorhynchus australis'') is a small dolphin found in the waters around Tierra del Fuego at the foot of South America. It is also commonly known as the black-chinned dolphin or even Peale's black-chinned dolphin. However, since Rice's work Peale's dolphin has been adopted as the standard common name. Taxonomy Though it is traditionally placed in the genus ''Lagenorhynchus'', recent molecular phylogeny, molecular analyses indicate Peale's dolphin is actually more closely related to the dolphins of the genus ''Cephalorhynchus''. If true, this would mean this species must either be transferred to ''Cephalorhynchus'' or be given a new genus of its own. An alternate genus proposed for this species (as well as the Pacific white-sided dolphin, hourglass dolphin and dusky dolphin is the resurrected genus ''Sagmatias''. Some behavioral and morphological data support moving Peale's dolphin to ''Cephalorhynchus''. According to , Peale's dolphin and the ''Cephalorhynchu ...

Yellow-billed Teal
The yellow-billed teal (''Anas flavirostris'') is a South American species of duck. Like other teals, it belongs to the diverse genus ''Anas''; more precisely it is one of the "true" teals of subgenus ''Nettion''. It occurs in Argentina, the Falkland Islands, Chile, Peru, Bolivia, Uruguay, and Brazil. It has also established itself in South Georgia, where it was first recorded breeding in 1971, and has been recorded as far east as Tristan da Cunha. It inhabits freshwater wetlands, preferring palustrine habitat to rivers. Considering its wide range and local abundance, it is not considered threatened by the IUCN. Description The namesake bill is bright yellow with a black tip and a black band along the ridge of the culmen. The species is somewhat similar to the larger yellow-billed pintail, but has a darker head, shorter neck and plain grayish sides. Taxonomy Mitochondrial DNA sequence data is most similar to that of the very different-looking green-winged teal.Johnson & So ...

Silver Teal
The silver teal or versicolor teal (''Spatula versicolor'') is a species of dabbling duck in the genus ''Spatula''. It breeds in South America. Between April and June they prefer reed beds and will lay 6 to 10 creamy-pink eggs. As with swans and geese, both parents will rear the ducklings. A pair may bond long term. It lives on fresh water in small groups, and feeds primarily on vegetable matter such as seeds and aquatic plants. The silver teal's range includes southern Bolivia, southern Brazil, Paraguay, Argentina, Chile, Uruguay, South Georgia, South Sandwich Islands, and the Falkland Islands.Clements, J. (2007) The southernmost birds migrate to southern Brazil in the winter. Silver teals are on the whole placid ducks but may be protective of eggs, young and females. Description They have a black cap that extends below the eyes, and a bluish bill with a yellow tip. They also have a green speculum with a white border. The Puna teal was previously regarded as a subspecies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-billed Pintail
The yellow-billed pintail (''Anas georgica'') is a South American dabbling duck of the genus ''Anas'' with three described subspecies. Taxonomy The yellow-billed pintail was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's '' Systema Naturae''. He placed it with all the ducks, geese and swans in the genus ''Anas'' and coined the binomial name ''Anas georgica''. Gmelin based his description on the "Georgia duck" that had been described in 1785 by the English ornithologist John Latham in his ''A General Synopsis of Birds''. The naturalist Joseph Banks had provided Latham with a water-colour drawing of the duck by Georg Forster who had accompanied James Cook on his second voyage to the Pacific Ocean. The watercolour was painted in 1775 on South Georgia. This picture is now the holotype for the species and is held by the Natural History Museum in London. The genus name ''Anas'' is the Latin wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying Steamer Duck
The flying steamer duck (''Tachyeres patachonicus''), also known as the flying steamer-duck or flying steamerduck, is a species of South American duck in the family Anatidae. Taxonomy and Systematics The flying steamer duck is one of four steamer ducks, in the genus ''Tachyeres'', which also includes the Fuegian steamer duck (''Tachyeres pteneres''), the Chubut steamer duck (''Tachyeres leucocephalus''), and the Falkland steamer duck (''Tachyeres brachypterus''). The steamer ducks are named for their method of mobility, as the manner in which they use wings and feet to paddle across the water resembles an old-time steam boat. The steamer ducks are members of the Southern Hemisphere shelducks clade Tadorninae. The three flightless species are monophyletic, with the flying steamer ducks splitting off phylogenetically. It is the only steamer duck which can fly, and the only one to occur on inland fresh waters. However, some individual male flying steamer ducks within the specie ...

White-rumped Sandpiper
The white-rumped sandpiper (''Calidris fuscicollis'') is a small shorebird that breeds in the northern tundra of Canada and Alaska. This bird can be difficult to distinguish from other similar tiny shorebirds; these are known collectively as "peeps" or "stints". These birds are not often spotted. In the summer, they are rarely seen because they are in such an obscure breeding location. Similarly, in the winter they are rarely seen because they travel too far south for many birdwatchers. Therefore, the majority of sightings occur during the spring or fall in temperate regions and are generally in small numbers around water. Taxonomy The white-rumped sandpiper is placed in the order Charadriiformes along with gulls, alcids, plovers and oystercatchers. Its family, Scolopacidae, encompasses all sandpipers, and as a stint it is classified in the genus Calidris. It is classified as monotypic species, meaning that no population differentiation or subspecies have been described. The gen ...

White-bridled Finch
The white-bridled finch (''Melanodera melanodera''), also known as the canary-winged finch or black-throated finch, is a small passerine bird belonging to the genus '' Melanodera'' together with the yellow-bridled finch (''M. xanthogramma''). Formerly placed in the family Emberizidae, it is now considered a tanager. It is found in grassland in southernmost South America. There are two subspecies: ''M. m. melanodera'' in the Falkland Islands and ''M. m. princetoniana'' in southern Argentina and Chile. Description The male is grey-green above and yellow below with a grey head and upper breast. It has a black throat and mask which are bordered with white. There are large yellow patches in the wings and tail. Females are brown with dark streaks. They have yellow outer tail feathers and yellow fringes to the wing feathers. It is long.

Magellanic Penguin
The Magellanic penguin (''Spheniscus magellanicus'') is a South American penguin, breeding in coastal Patagonia, including Argentina, Chile, and the Falkland Islands, with some migrating to Brazil and Uruguay, where they are occasionally seen as far north as Espirito Santo. Vagrants have been found in El Salvador, the Avian Island in Antarctica, Australia, and New Zealand. It is the most numerous of the ''Spheniscus'' penguins. Its nearest relatives are the African penguin, the Humboldt penguin, and the Galápagos penguins. The Magellanic penguin was named after Portuguese explorer Ferdinand Magellan, who spotted the birds in 1520. The species is listed as being of Least Concern by the IUCN. Description Magellanic penguins are medium-sized penguins which grow to be tall and weigh between . The males are larger than the females, and the weight of both drops while the parents raise their young. Adults have black backs and white abdomens. There are two black bands between the ...
