Australian Shelduck
The Australian shelduck (''Tadorna tadornoides''), also known as the chestnut-breasted shelduck or mountain duck, is a shelduck, a group of large goose-like ducks part of the bird family Anatidae. The genus name ''Tadorna'' comes from Celtic roots and means "pied waterfowl". They have a striking chestnut-coloured breast and black body. They are protected under the National Parks and Wildlife Act 1974. Taxonomy and naming William Jardine and Prideaux John Selby described the Australian shelduck in 1828. Description The males are mostly dark, with a chestnut breast. They have white neck collars and dark green heads. The females are similar, but they have white around the eyes and are smaller. Both males and females have chestnut and black wings with a green speculum, and show some white on their wings during flight. The downy young are white with a brown crown and brown stripes from crown to tail. Juvenile males are duller than the adults and also lack a white collar, while juv ...

William Jardine (naturalist)
Sir William Jardine, 7th Baronet of Applegarth FRS FRSE FLS FSA (23 February 1800 – 21 November 1874) was a Scottish naturalist. He is known for his editing of a long series of natural history books, ''The Naturalist's Library''. Life and work Jardine was born on 23 February 1800 at 28 North Hanover Street in Edinburgh, the son of Sir Alexander Jardine, 6th baronet of Applegarth and his wife, Jane Maule. He was educated in both York and Edinburgh then studied medicine at Edinburgh University. From 1817 to 1821 he lodged with Rev Dr Andrew Grant at James Square, an arrangement made by his father. Grant was minister of St Andrew's Church on George Street. In his early years, aged only 25, he was elected a fellow of the Royal Society of Edinburgh his proposer being Sir David Brewster. He was a co-founder of the Berwickshire Naturalists' Club, and contributed to the founding of the Ray Society. He was "keenly addicted to field-sports, and a master equally of the rod ...

Prideaux John Selby
Prideaux John Selby FRSE FLS (23 July 1788 – 27 March 1867) was an English ornithologist, botanist and natural history artist. Life Selby was born in Bondgate Street in Alnwick in Northumberland, the eldest son of George Selby of Beal and Twizell (d.1804), and his wife, Margaret Cook. He was educated at Durham School. He studied at University College, Oxford. He succeeded in 1804 to the family estates at Beal, and added to the landholdings there at a cost of some £14000 in about 1840. He sold the Beal estate amounting to in 1850 for £47000 (£ at today's prices). He died at Twizell House and was buried in Bamburgh churchyard.

Shelduck
The shelducks, most species of which are found in the genus ''Tadorna'' (except for the Radjah shelduck, which is now found in its own monotypic genus ''Radjah''), are a group of large birds in the Tadorninae subfamily of the Anatidae, the biological family that includes the ducks and most duck-like waterfowl such as the geese and swans. Biology Shelducks are a group of large, often semi-terrestrial waterfowl, which can be seen as intermediate between geese (''Anserinae'') and ducks. They are mid-sized (some 50–60 cm) Old World waterfowl. The sexes are colored slightly differently in most species, and all have a characteristic upperwing coloration in flight: the tertiary remiges form a green speculum, the secondaries and primaries are black, and the coverts (forewing) are white. Their diet consists of small shore animals ( winkles, crabs etc.) as well as grasses and other plants. They were originally known as "sheldrakes", which remained the most common name until the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goose
A goose ( : geese) is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera ''Anser'' (the grey geese and white geese) and '' Branta'' (the black geese). Some other birds, mostly related to the shelducks, have "goose" as part of their names. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller. The term "goose" may refer to either a male or female bird, but when paired with "gander", refers specifically to a female one (the latter referring to a male). Young birds before fledging are called goslings. The collective noun for a group of geese on the ground is a gaggle; when in flight, they are called a skein, a team, or a wedge; when flying close together, they are called a plump. Etymology The word "goose" is a direct descendant of,''*ghans-''. In Germanic languages, the root gave Old English ''gōs'' with the plural ''gēs'' and ''gandres'' (b ...

Duck
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid confusion with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatidae
The Anatidae are the biological family of water birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water. The family contains around 174 species in 43 genera. (The magpie goose is no longer considered to be part of the Anatidae and is now placed in its own family, Anseranatidae.) They are generally herbivorous, and are monogamous breeders. A number of species undertake annual migrations. A few species have been domesticated for agriculture, and many others are hunted for food and recreation. Five species have become extinct since 1600, and many more are threatened with extinction. Description and ecology The ducks, geese, and swans are small- to large-sized birds with a broad and elongated general body plan. Diving species vary from this in being rounder. Extant s ...

Moulting
In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is the manner in which an animal routinely casts off a part of its body (often, but not always, an outer layer or covering), either at specific times of the year, or at specific points in its life cycle. In medieval times it was also known as "mewing" (from the French verb "muer", to moult), a term that lives on in the name of Britain's Royal Mews where the King's hawks used to be kept during moulting time before becoming horse stables after Tudor times. Moulting can involve shedding the Epidermis (skin), epidermis (skin), pelage (hair, feathers, fur, wool), or other external layer. In some groups, other body parts may be shed, for example, the entire exoskeleton in arthropods, including the wings in some insects. Examples In birds In birds, moulting is the periodic replacement of feathers by shedding old feathers while producing new o ...

Lake George (New South Wales)
Lake George (or Weereewa in the Ngunnawal language) is an Endorheic basin, endorheic lake in south-eastern New South Wales, Australia. It is approximately north-east of Canberra located adjacent to the Federal Highway (Australia), Federal Highway en route to and Sydney. Lake George is also the name of a locality on the western and southern edges of the lake, within the area of the Queanbeyan–Palerang Regional Council. Geography and hydrology Lake George is an endorheic lake, as it has no outflow of water to rivers and oceans. The lake is believed to be more than a million years old. Originally, small streams drained its Drainage basin, catchment into the Yass River, but then the Lake George Escarpment rose due to major crust movement along a strong Fault (geology), fault line, blocking this drainage and forming the lake. Lake George has in previous Ice age, Ice Ages been much larger and deeper. The thickness of sediment beneath the lake exceeds , according to a Bureau of ...
