Topknot Pigeon
The topknot pigeon (''Lopholaimus antarcticus'') is a pigeon native to eastern Australia. Taxonomy English naturalist George Shaw described the topknot pigeon as ''Columba antarctica'' in 1793. The topknot pigeon is sister taxon to a lineage that gave rise to the mountain pigeons (''Gymnophaps'') of New Guinea, the common ancestor of both diverged from a lineage that gave rise to the kereru and Chatham pigeon. "Topknot pigeon" has been designated the official common name by the International Ornithologists' Union (IOC); John Gould noted in 1848 that it had been given this name by the colonists of New South Wales. It is also known by the name of "flock pigeon". Description The topknot pigeon is a large predominately slate-grey bird, in length. The back, coverts and upper secondaries are a darker slate-grey with black quills. The primaries are black, the remaining body in a lighter slate-grey in colour. The chest and hind neck are notched, showing dark bases giving a streak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elizabeth Gould (illustrator)
Elizabeth Gould, née Coxen (1804—1841), was a British artist and illustrator at the forefront of the natural history movement. Elizabeth traveled and worked alongside her husband, naturalist and author John Gould. She produced illustrations and lithographs for ornithological works, including plates in Darwin's '' The Zoology of the Voyage of H.M.S. Beagle'' and the Goulds' seminal work '' The Birds of Australia''. In total, Elizabeth is accredited to at least 650 works. Life and artistic career Elizabeth was born on 18 July 1804 in Ramsgate, England to a military family. Little is known of her early life, however it is likely that Elizabeth Elizabeth likely underwent training in drawing and botany from a young age. In Victorian England, botany and natural history were part of the education of girls in middle-class English families. As Ann Moyal stated, “Cultivated women drew, walked, observed, collected specimens, arranged and painted." After this, at twenty-two, Elizabe ...

Frugivore
A frugivore is an animal that thrives mostly on raw fruits or succulent fruit-like produce of plants such as roots, shoots, nuts and seeds. Approximately 20% of mammalian herbivores eat fruit. Frugivores are highly dependent on the abundance and nutritional composition of fruits. Frugivores can benefit or hinder fruit-producing plants by either dispersing or destroying their seeds through digestion. When both the fruit-producing plant and the frugivore benefit by fruit-eating behavior the interaction is a form of mutualism. Frugivore seed dispersal Seed dispersal is important for plants because it allows their progeny to move away from their parents over time. The advantages of seed dispersal may have led to the evolution of fleshy fruits, which entice animals to consume them and move the plant's seeds from place to place. While many fruit-producing plant species would not disperse far without frugivores, their seeds can usually germinate even if they fall to the ground directl ...

Birds Described In 1794
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Australia
This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. For an overview of this subject see Endemism in birds. Patterns of endemism Family-level endemism is prominent in Australia. The Australasian biogeographic region has the highest number of endemic families of any zoogeographic region except the Neotropics, and many of these families are endemic to Australia itself — the country therefore stakes a strong claim to be the world's greatest hotspot of bird endemism. Australian endemic and near-endemic families The Australian endemic families are: * Emu (Dromaiidae), a well-known monotypic family; the emu is found in rural areas throughout the continent * Plains-wanderer (Pedionomidae), a monotypic family; plains-wanderer is restricted to arid inland areas in the southeast of Australia * Lyrebirds (Menuridae), two forest-dwelling species of southeast Australia * Scrub-birds (Atrichornithidae), two fore ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
