Gray's Grasshopper Warbler
Gray's grasshopper warbler (''Helopsaltes fasciolatus''), also known as Gray's warbler, is a species of grass warbler in the family Locustellidae; it was formerly included in the "Old World warbler" assemblage. The Sakhalin grasshopper warbler was formerly considered conspecific. Distribution and habitat This small passerine bird breeds in southern Siberia, northeastern China and Korea. It is migratory, wintering in southeast Asia. It is a species found in lowland and coastal regions, nesting in forests or thickets. Description This is the largest of all the ''Locustella'' warblers, approaching the size of the great reed warbler. The adult has an unstreaked olive-brown back, uniformly grey breast and buff underparts, with unmottled dull orange undertail coverts. The song is a short phrase, loud and distinctive; nothing like the insect-like reeling of European ''Locustella'' species, and more musical than that of Pallas's grasshopper warbler.

Grass Warbler
The grass warblers are small passerine birds belonging to the genus ''Locustella''. Formerly placed in the paraphyletic "Old World warbler" assemblage, they are now considered the northernmost representatives of a largely Gondwanan family, the Locustellidae. These are rather drab brownish "warblers" usually associated with fairly open grassland, shrubs or marshes. Some are streaked, others plain, all are difficult to view. They are insectivorous. The most characteristic feature of this group is that the song of several species is a mechanical insect-like reeling which gives rise to the group's scientific name. Species breeding in temperate regions are strongly migratory. Taxonomy The genus ''Locustella'' was introduced by the German naturalist Johann Jakob Kaup in 1829 with the common grasshopper warbler (''Locustella naevia'') as the type species. The genus name ''Locustella'' is from Latin and is a diminutive of ''locusta'', "grasshopper". Like the English name, this refe ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Birds Described In 1861
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Helopsaltes
''Helopsaltes'' is a genus of passerine birds in the grassbird family Locustellidae. A comprehensive molecular phylogenetic study of the grassbird family Locustellidae published in 2018 found that the genus '' Locustella'' consisted of two distinct clades. The genus was split and six species were moved to the newly erected genus ''Helopsaltes'' with Pallas's grasshopper warbler (''Helopsaltes certhiola'') as the type species. The genus name combines the Ancient Greek ἕλος/''helos'' meaning "marshy ground" and ψάλτης/''psaltis'' "a chanter". The genus contains the following species: * Sakhalin grasshopper warbler (''Helopsaltes amnicola'') * Gray's grasshopper warbler Gray's grasshopper warbler (''Helopsaltes fasciolatus''), also known as Gray's warbler, is a species of grass warbler in the family (biology), family Locustellidae; it was formerly included in the "Old World warbler" assemblage.

Pallas's Grasshopper Warbler
Pallas's grasshopper warbler (''Helopsaltes certhiola''), also known as the rusty-rumped warbler, is an Old World warbler in the grass warbler genus ''Helopsaltes''. It breeds in the eastern Palearctic: from the Altai Mountains, Mongolia and Transbaikalia to northeastern China, the Korean Peninsula, and islands in the Sea of Okhotsk (Sakhalin and Kuril Islands). It is migratory, wintering from India eastward to Indonesia. It is a rare migrant in Sri Lanka. Etymology This bird was named after the German zoologist Peter Simon Pallas. The specific ''certhiola'' is a diminutive from the genus ''Certhia'', the treecreepers. The sixth edition of ''Clements Checklist'' Clements, James F. (2007) ''The Clements Checklist of Birds of the World'' Cornell University Press refers to this species as "Pallas's warbler", a name more commonly used for '' Phylloscopus proregulus.'' Habitat This small passerine bird is found in tall grass with some thicker vegetation, usually close to water in ... [...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] |
Great Reed Warbler
The great reed warbler (''Acrocephalus arundinaceus'') is a Eurasian passerine in the genus '' Acrocephalus''. The genus name ''Acrocephalus'' is from Ancient Greek ''akros'', "highest", and ''kephale'', "head". It is possible that Naumann and Naumann thought ''akros'' meant "sharp-pointed". The specific ''arundinaceus'' is from Latin and means "like a reed", from ''arundo, arundinis'', "reed". It used to be placed in the Old World warbler assemblage, but is now recognized as part of the marsh and tree-warbler family (Acrocephalidae). Great reed warblers are medium-sized birds and are the largest of the European warblers. They breed throughout mainland Europe and the west Palearctic and migrate to sub-Saharan Africa in the winter. Great reed warblers favour reed beds as their habitat during breeding months, while living in reed beds, bush thickets, rice fields, and forest clearings during the winter. Great reed warblers exhibit relatively low sexual dimorphism, and both genders ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Korea
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic of Korea) comprising its southern half. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. The peninsula is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan (East Sea). During the first half of the 1st millennium, Korea was divided between three states, Goguryeo, Baekje, and Silla, together known as the Three Kingdoms of Korea. In the second half of the 1st millennium, Silla defeated and conquered Baekje and Goguryeo, leading to the "Unified Silla" period. Meanwhile, Balhae formed in the north, superseding former Goguryeo. Unified Silla eventually collapsed into three separate states due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
