Pitta
Pittas are a family, Pittidae, of passerine birds found in Asia, Australasia and Africa. There are thought to be 40 to 42 species of pittas, all similar in general appearance and habits. The pittas are Old World suboscines, and their closest relatives among other birds are in the genera ''Smithornis '' and ''Calyptomena''. Initially placed in a single genus, as of 2009 they have been split into three genera: ''Pitta'', ''Erythropitta'' and ''Hydrornis''. Pittas are medium-sized by passerine standards, at in length, and stocky, with strong, longish legs and long feet. They have very short tails and stout, slightly decurved bills. Many have brightly coloured plumage. Most pitta species are tropical; a few species can be found in temperate climates. They are mostly found in forests, but some live in scrub and mangroves. They are highly terrestrial and mostly solitary, and usually forage on wet forest floors in areas with good ground cover. They eat earthworms, snails, inse ...

Pitta (genus)
__NOTOC__ ''Pitta'' is a genus of birds in the Pittidae, or pitta family (biology), family. They are secretive, brightly coloured birds that forage on the forest floor. They are long-legged and short-tailed with rounded wings. They all have green on their upperparts with blue wing-patches. Many have dark heads. Nest construction, incubation and rearing of nestlings is performed by both parents. Incubation is completed in some 17 days, and the nestlings are altricial and nidicolous. Some species are migratory. The antpittas, a Neotropical bird family of some 50 species, resemble the pittas in their hopping gait, furtive behaviour, long legs and short tails. Taxonomy The genus ''Pitta'' was erected by the French ornithologist Louis Jean Pierre Vieillot in 1816. In 1855 the English ornithologist George Robert Gray designated the type species as ''Corvus triostegus'' Anders Sparrman, Sparrman. This is a Synonym (taxonomy)#Zoology, junior synonym of ''Corvus brachyura'' Carl Linnaeus, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hooded Pitta
The hooded pitta (''Pitta sordida'') is a passerine bird in the family Pittidae. It is common in eastern and southeastern Asia and maritime Southeast Asia, where it lives in several types of forests as well as on plantations and other cultivated areas. It is a green bird with a black head and chestnut crown. It forages on the ground for insects and their larvae, and also eats berries. It breeds between February and August, the pair being strongly territorial and building their nest on the ground. Incubation and care of the fledglings is done by both parents. The bird has a wide range, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern". Taxonomy The hooded pitta was described by the German zoologist Philipp Statius Müller in 1776 and given the binomial name ''Turdus sordidus''. Statius Müller's description was based on a plate showing the "Merle des Philippines" published by Comte de Buffon in his ''Planches E ...

Erythropitta
250px, Black-crowned pitta (''E. ussheri'') uttering whistles from a perch in Danum Valley, Sabah ''Erythropitta'' is a genus of pitta. The members of the genus are found mostly in South-east Asia, with one species, the Papuan pitta, ranging into northeast Australia. The genus was formerly merged with the large genus ''Pitta'', but a 2006 study split the family into three genera. Taxonomy The pittas were at one time all usually placed in the genus ''Pitta'', the only genus in the family Pittidae, but when a 2006 molecular phylogenetic study found that the pittas formed three separate groups, the genus was split and some species were moved into two resurrected genera, ''Erythropitta'' and '' Hydrornis''. The genus ''Erythropitta'' had been introduced in 1854 by the French naturalist Charles Lucien Bonaparte. The type species was subsequently designated as the Papuan pitta (''Erythropitta macklotii''). The name ''Erythropitta'' combines the Ancient Greek Ancient Gre ...

Hydrornis
''Hydrornis'' is a genus of pitta in the family Pittidae. The genus contains thirteen species, found in South-east Asia. The genus was formerly merged with the genus ''Pitta'', but a 2006 study split the family into three genera. Taxonomy The pittas were at one time all usually placed in the genus ''Pitta'', the only genus in the family Pittidae, but when a 2006 molecular phylogenetic study found that the pittas formed three separate groups, the genus was split and some species were moved into two resurrected genera, ''Erythropitta'' and ''Hydrornis''. The genus ''Hydrornis'' had been introduced by the English zoologist Edward Blyth in 1843 with the blue-naped pitta (''Hydrornis nipalensis'') as the type species. The name ''Hydrornis'' combines the Ancient Greek words "water" and "bird". The pittas in ''Hydrornis'' have sexually dimorphic Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological chara ...

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three clades: Acanthisitti (New Zealand wrens), Tyranni (suboscines), and Passeri (oscines or songbirds). The passe ...

Suboscine
The Tyranni (suboscines) are a suborder of passerine birds that includes more than 1,000 species, the large majority of which are South American. It is named after the type genus '' Tyrannus''. These have a different anatomy of the syrinx musculature than the oscines (songbirds of the larger suborder Passeri), hence the common name of ''suboscines''. The available morphological, DNA sequence, and biogeographical data, as well as the (scant) fossil record, agree that these two major passerine suborders are evolutionarily distinct clades. Systematics The suborder Tyranni is divided into two infraorders: the Eurylaimides and the Tyrannides. The New Zealand wrens in the family Acanthisittidae are placed in a separate suborder Acanthisitti. The Eurylaimides contain the Old World suboscines – mainly distributed in tropical regions around the Indian Ocean – and a single American species, the sapayoa: * Philepittidae: asities * Eurylaimidae: typical broadbills * Calyptome ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, a ... [...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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Egg
Bird eggs are laid by the females and range in quantity from one (as in condors) to up to seventeen (the grey partridge). Clutch size may vary latitudinally within a species. Some birds lay eggs even when the eggs have not been fertilized; it is not uncommon for pet owners to find their lone bird nesting on a clutch of infertile eggs, which are sometimes called wind-eggs. Anatomy All bird eggs contain the following components: * The embryo is the immature developing chick * The amnion is a membrane that initially covers the embryo and eventually fills with amniotic fluid, provides the embryo with protection against shock from movement * The allantois helps the embryo obtain oxygen and handles metabolic waste * The chorion, together with the amnion, forms the amniotic sac and encloses the amnion, vitellus, and the embryo * The vitellus, or yolk, is the nutrient-bearing portion of the egg, containing most of its fat, minerals, and many of its proteins and blood vessels * The al ...

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 buil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about fiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
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 wide ...
