Ocyphaps
The crested pigeon (''Ocyphaps lophotes'') is a bird found widely throughout mainland Australia except for the far northern tropical areas. Only two Australian pigeon species possess an erect crest, the crested pigeon and the spinifex pigeon. The crested pigeon is the larger of the two species. The crested pigeon is sometimes referred to as a topknot pigeon, a common name shared with the reddish crested '' Lopholaimus antarcticus'' of Eastern Australia. Taxonomy The species was described in 1822 by Temminck; it is the only species in the genus ''Ocyphaps'', established by G.R. Gray in 1842. Two subspecies are recognized: ''O. l. lophotes'', the nominate subspecies, occurring across the south of the continent; and ''O. l. whitlocki'', occurring in regions of the centre and north of Western Australia. The taxon was named for F. Lawson Whitlock, who made important collections of bird specimens in those areas. The species has also been placed as ''Geophaps'', perhaps allied with ...

Geophaps
''Geophaps'' is a small genus of doves in the order Columbiformes. Established by George Robert Gray, it contains three extant species. The plumage and distribution suggests that all species within the genus have formed from a common ancestor and that through adaptive radiation they have varied greatly in size, shape and ecology. Taxonomy The genus ''Geophaps'' was introduced in 1842 to accommodate the squatter pigeon (''Geophaps scripta'') by the English zoologist George Robert Gray. The genus name combines of the Ancient Greek ''geō'' meaning "ground" and ''phaps'', meaning "pigeon". Pigeons and doves are placed in their taxonomic groups based predominantly on structural characteristics. Pigeons feed their young by regurgitation and suck water while their beak is immersed. Males and females divide incubation duties. ''Geophaps'' pigeons are members of the family Columbidae, whose distribution is spread between three defined areas around the globe: the Americas; Afri ...

Bronzewing Pigeon
The bronzewing pigeons are a group of pigeons native to Australia which have distinctive iridescent wing patches that appear bronze or green-brown in dull light, but flash in many bright colours in the sun as the bird moves. Three species are always known as "bronzewings" in the genus ''Phaps'', and several broadly similar birds also have the trademark wing patch to a more or less obvious degree. Bronzewings are ground feeders, but are capable of very fast flight. They tend to browse quietly until disturbed, then remain still, their earthy browns blending into the earth and leaf litter until the intruder approaches too closely, when the bronzewings take off with an explosive burst of sudden wing clapping and feather noise, and disappear from sight within moments. The dividing line between the bronzewings and the rock pigeons is arbitrary; essentially, rock pigeons are bronzewings without bronze on their wings. Members of the group include: * The common bronzewing (''Phaps chalcop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbidae
Columbidae () is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon. Doves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spotted Dove
The spotted dove (''Spilopelia chinensis'') is a small and somewhat long-tailed pigeon that is a common resident breeding bird across its native range on the Indian subcontinent and in Southeast Asia. The species has been introduced to many parts of the world and feral populations have become established. This species was formerly included in the genus ''Streptopelia'' with other turtle-doves, but studies suggest that they differ from typical members of that genus. This dove is long tailed buff brown with a white-spotted black collar patch on the back and sides of the neck. The tail tips are white and the wing coverts have light buff spots. There are considerable plumage variations across populations within its wide range. The species is found in light forests and gardens as well as in urban areas. They fly from the ground with an explosive flutter and will sometimes glide down to a perch. It is also called the mountain dove, pearl-necked dove, lace-necked dove, and spotted turtl ...

Whistle
A whistle is an instrument which produces sound from a stream of gas, most commonly air. It may be mouth-operated, or powered by air pressure, steam, or other means. Whistles vary in size from a small slide whistle or nose flute type to a large multi-piped church organ. Whistles have been around since early humans first carved out a gourd or branch and found they could make sound with it. In prehistoric Egypt, small shells were used as whistles. Many present day wind instruments are inheritors of these early whistles. With the rise of more mechanical power, other forms of whistles have been developed. One characteristic of a whistle is that it creates a pure, or nearly pure, tone. The conversion of flow energy to sound comes from an interaction between a solid material and a fluid stream. The forces in some whistles are sufficient to set the solid material in motion. Classic examples are Aeolian tones that result in galloping power lines, or the Tacoma Narrows Bridge (the ...

Predator
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and i ...

George Robert Gray
George Robert Gray FRS (8 July 1808 – 6 May 1872) was an English zoologist and author, and head of the ornithological section of the British Museum, now the Natural History Museum, in London for forty-one years. He was the younger brother of the zoologist John Edward Gray and the son of the botanist Samuel Frederick Gray. George Gray's most important publication was his ''Genera of Birds'' (1844–49), illustrated by David William Mitchell and Joseph Wolf, which included 46,000 references. Biography He was born in Little Chelsea, London, to Samuel Frederick Gray, naturalist and pharmacologist, and Elizabeth (née Forfeit), his wife. He was educated at Merchant Taylor's School. Gray started at the British Museum as Assistant Keeper of the Zoology Branch in 1831. He began by cataloguing insects, and published an ''Entomology of Australia'' (1833) and contributed the entomogical section to an English edition of Georges Cuvier's ''Animal Kingdom''. Gray described many spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golf
Golf is a club-and-ball sport in which players use various clubs to hit balls into a series of holes on a course in as few strokes as possible. Golf, unlike most ball games, cannot and does not use a standardized playing area, and coping with the varied terrains encountered on different courses is a key part of the game. Courses typically have either 18 or 9 ''holes'', regions of terrain that each contain a ''cup'', the hole that receives the ball. Each hole on a course contains a teeing ground to start from, and a putting green containing the cup. There are several standard forms of terrain between the tee and the green, such as the fairway, rough (tall grass), and various ''hazards'' such as water, rocks, or sand-filled ''bunkers''. Each hole on a course is unique in its specific layout. Golf is played for the lowest number of strokes by an individual, known as stroke play, or the lowest score on the most individual holes in a complete round by an individual or team, k ...
