Leucosarcia
The wonga pigeon (''Leucosarcia melanoleuca'') is a dove, pigeon that inhabits areas in eastern Australia with its range being from Central Queensland to Gippsland, eastern Victoria, Australia. Distribution and habitat Previously they could be found as north as Cairns and as south as the Dandenongs, but due to land clearance, shootings in the 1940s for crop protection, and fox predation, they are rarely seen in these areas, but their populations have improved. Description The wonga pigeon is a large, plump pigeon that has a short neck, broad wings, and a long tail. Its length varies from 38 to 40 centimetres (15.2 to 16 inches). It has pastel blue-grey back feathers. The head fades to a creamy-white colour. The underside is white with dotted dark grey spots such that a white V can be seen on its chest. Their eyes are a dark red-brown colour and they have pink eye-rings that encircle them. Legs are red and the sexes appear identical but Juvenile (organism), immature pigeons ...

Dove
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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist. He published a number of monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. He has been considered the father of bird study in Australia and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained a position on an estate near Guildford, Surrey, and then in 1818, Gould Snr became foreman in the Royal Gardens of Windsor. Gould then be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Birds Of Victoria (Australia)
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 ...

Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the o ...

Tawny Frogmouth
The tawny frogmouth (''Podargus strigoides'') is a species of frogmouth native to the Australian mainland and Tasmania and found throughout. It is a big-headed, stocky bird, often mistaken for an owl, due to its nocturnal habits and similar colouring, and sometimes, at least archaically, referred to as ''mopoke'' or ''mopawk'', a name also used for the Australian boobook, the call of which is often confused with that of the tawny frogmouth. Names Its name in reconstructed Proto-Pama–Nyungan is ''*tawa'' or ''*tawu''.Alpher, Barry. 2004. Pama-Nyungan: Phonological Reconstruction and Status as a Phylo-Genetic Group.

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] |
Bird Nest
A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere across and high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than in diameter and stand nearly tall. The study of birds' nests is known as ''caliology''. Not all bird species bui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
