Striated Pardalote
The striated pardalote (''Pardalotus striatus'') is the least colourful and most common of the four pardalote species. Other common names include pickwick, wittachew and chip-chip. It is a very small, short-tailed bird that is more often heard than seen, foraging noisily for lerps and other small creatures in the treetops. Taxonomy Four full species were originally named, and are clearly recognisable in the field. They are now classified as merely well-defined subspecies instead. * The yellow-tipped pardalote (subspecies ''striatus'') is found mainly in Tasmania, but crosses the 200 miles of Bass Strait to the mainland each winter in a migration. * The striated pardalote, subspecies ''substriatus'', central and western Australia. * The eastern striated or red-tipped pardalote, subspecies ''ornatus'', from the sub-tropical east coast, including the Sydney region. * Two subspecies of the black-headed pardalote, ''melanocephalus'' and ''uropygialis'', from north-eastern New South ...

Birds Described In 1789
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

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 ...

Pardalote
Pardalotes or peep-wrens are a family, Pardalotidae, of very small, brightly coloured birds native to Australia, with short tails, strong legs, and stubby blunt beaks. This family is composed of four species in one genus, ''Pardalotus'', and several subspecies. The name derives from a Greek word meaning "spotted". The family once contained several other species now split into the family Acanthizidae. Pardalotes spend most of their time high in the outer foliage of trees, feeding on insects, spiders, and above all lerps (a type of sap-sucking insect). Their role in controlling lerp infestations in the eucalyptus forests of Australia may be significant. They generally live in pairs or small family groups but sometimes come together into flocks after breeding. Pardalotes are seasonal breeders in temperate areas of Australia but may breed year round in warmer areas. They are monogamous breeders, and both partners share nest construction, incubation and chick-rearing duties. All fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rainforest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of lea ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-browed Pardalote
The red-browed pardalote (''Pardalotus rubricatus'') is a small brightly coloured insectivorous passerine, endemic to Australia . A gleaning specialist, they forage primarily in eucalypt trees . The Latin word ''rubricatus'' means 'red-ochred' which is descriptive of their orange-red eyebrow . Other common names include red-browed diamondbird, bellbird, cape red-browed, pale red-browed, fawn-eyed, fawn-eyebrowed and pallid or red-lored pardalote . Taxonomy Red-browed pardalotes belong to the order Passeriformes and family Pardalotidae of which four species are recognised: red-browed pardalote ''Pardalotus rubricatus'', spotted pardalote ''Pardalotus punctatus'', forty-spotted pardalote ''Pardalotus quadragintus'' and striated pardalote ''Pardalotus striatus''. Historically, the family Pardalotidae included pardalotes and acanthizid warblers; gerygones, scrubwrens and thornbills . However, recent phylogenetic and morphological studies , indicate that pardalotes are more clos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spotted Pardalote
The spotted pardalote (''Pardalotus punctatus'') is one of the smallest of all Australian birds at in length, and one of the most colourful; it is sometimes known as the diamondbird. Although moderately common in all of the reasonably fertile parts of Australia (the east coast, the south-east, and the south-west corner) it is seldom seen closely enough to enable identification. Three subspecies are recognised. The wet tropics spotted pardalote (subspecies ''militaris'') is found in northeastern Queensland, while the distinctive subspecies, the yellow-rumped pardalote (subspecies ''xanthopyge''), is mostly found in drier inland regions of southern Australia, particularly in semi-arid Mallee woodlands. Also occasionally found nesting in burrows in semi-rainforest areas inland from the coast in Mid North Coast NSW Taxonomy The spotted pardalote was described by English naturalist George Shaw and drawn by Frederick Polydore Nodder in the 1792 work ''The Naturalist's Miscellany: ...
