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 ...

Phillip Parker King
Rear Admiral Phillip Parker King, FRS, RN (13 December 1791 – 26 February 1856) was an early explorer of the Australian and Patagonian coasts. Early life and education King was born on Norfolk Island, to Philip Gidley King and Anna Josepha King ''née'' Coombe, and named after his father's mentor, Admiral Arthur Phillip (1738–1814), (first governor of New South Wales and founder of the British penal colony which later became the city of Sydney in Australia), which explains the difference in spelling of his and his father's first names. King was sent to England for education in 1796, and he joined the Royal Naval Academy, at Portsmouth, in county Hampshire, England in 1802. King entered the Royal Navy in 1807, where he was commissioned lieutenant in 1814. Expeditions in Australia King was assigned to survey the parts of the Australian coast not already examined by Royal Navy officer, Matthew Flinders, (who had already made three earlier exploratory voyages between 17 ...

Egg Predation
Egg predation is a feeding strategy in many groups of animals (ovivores) in which they consume eggs. Since an egg represents a complete organism at one stage of its life cycle, eating an egg is a form of predation, the killing of another organism for food. Egg predation is found widely across the animal kingdom, including in fish, birds, snakes, mammals, and arthropods. Some species are specialist egg predators, but many more are generalists which take eggs when the opportunity arises. Humans have accidentally or intentionally introduced egg predators such as rats to places that had been free of them, causing damage to native species such as ground-nesting seabirds. Predatory birds such as ravens and gulls have spread, threatening ground-nesting birds such as sage grouse and terns. Measure to control such predators include the use of poisoned bait eggs. Definitions An ovivore or ovivorous animal is one that eats eggs, from Latin , egg, and , to devour. An obligate ovivore o ...

Tachyeres
The steamer ducks are a genus (''Tachyeres'') of ducks in the family Anatidae. All of the four species occur at the southern cone of South America in Chile and Argentina, and all except the flying steamer duck are flightless; even this one species capable of flight rarely takes to the air. They can be aggressive and are capable of chasing off predators like petrels. Bloody battles of steamer ducks with each other over territory disputes are observed in nature. They even kill waterbirds that are several times their size. Taxonomy The genus ''Tachyeres'' was introduced in 1875 by the English zoologist Richard Owen to accommodate the Falkland steamer duck. The genus name ''Tachyeres'', "having fast oars" or "fast rower", comes from Ancient Greek ταχυ- "fast" + ἐρέσσω "I row (as with oars)". The common name "steamer ducks" arose because, when swimming fast, they flap their wings into the water as well as using their feet, creating an effect like a paddle steamer. They ...

Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Hooded Grebe
The hooded grebe (''Podiceps gallardoi''), is a medium-sized grebe found in the southern region of Argentina. It grows to about in length, and is black and white in color. It is found in isolated lakes in the most remote parts of Patagonia and spends winters along the coast of the same region. In 2012 IUCN uplisted the species from Endangered to Critically Endangered. Ecology During the breeding season the hooded grebe is found on basaltic lakes in the Patagonian steppes at elevations of 500–1,200 m.Chebez, Juan Carlos. Los que se van: especies argentinas en peligro. No. 596 (822) CHE. 1999. Both saline and bitter salt lakes are used by non breeding flocks and some birds which winter on the coast of Argentina. The grebe requires aquatic vegetation in its breeding lakes (primarily ''Myriophyllum elatinoides'') which it uses to build its nest. The vegetation is also the habitat of the aquatic invertebrates on which the hooded grebe feeds. For example, in the week after hatching ...

American Mink
The American mink (''Neogale vison'') is a semiaquatic species of mustelid native to North America, though human intervention has expanded its range to many parts of Europe, Asia and South America. Because of range expansion, the American mink is classed as a least-concern species by the IUCN. The American mink was formerly thought to be the only extant member of the genus ''Neovison'' following the extinction of the sea mink (''N. macrodon''), but recent studies, followed by taxonomic authorities, have reclassified it and the sea mink within the genus ''Neogale'', which also contains a few New World weasel species. The American mink is a carnivore that feeds on rodents, fish, crustaceans, frogs, and birds. In its introduced range in Europe it has been classified as an invasive species linked to declines in European mink, Pyrenean desman, and water vole populations. It is the animal most frequently farmed for its fur, exceeding the silver fox, sable, marten, and skunk in econo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
