Dark-sided Flycatcher
The dark-sided flycatcher (''Muscicapa sibirica'') is a small passerine bird belonging to the genus ''Muscicapa'' in the Old World flycatcher family Muscicapidae. It has a wide breeding distribution in the East Palearctic with northern birds migrating south for the winter. It is also known as the Siberian flycatcher or sooty flycatcher, the latter name is also used for the sooty flycatcher (''M. infuscata'') of Africa. Taxonomy The dark-sided flycatcher was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the flycatchers in the genus ''Muscicapa'' and coined the binomial name ''Muscicapa sibirica''. Gmelin based his account on the "Dunn flycatcher" that had been described in 1783 by the English ornithologist John Latham in his multi-volume work ''A General Synopsis of Birds''. Latham reported that the bird was found around Lake Baikal in southern Siberi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siberia
Siberia ( ; rus, Сибирь, r=Sibir', p=sʲɪˈbʲirʲ, a=Ru-Сибирь.ogg) is an extensive geographical region, constituting all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has been a part of Russia since the latter half of the 16th century, after the Russians conquered lands east of the Ural Mountains. Siberia is vast and sparsely populated, covering an area of over , but home to merely one-fifth of Russia's population. Novosibirsk, Krasnoyarsk and Omsk are the largest cities in the region. Because Siberia is a geographic and historic region and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia extends eastwards from the Ural Mountains to the Pacific Ocean, and includes most of the drainage basin of the Arctic Ocean. The river Yenisey divides Siberia into two parts, Western and Eastern. Siberia stretches southwards from the Arctic Ocean to the hills of north-ce ...

Hokkaidō
is Japan's second largest island and comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaidō from Honshu; the two islands are connected by the undersea railway Seikan Tunnel.

Sakhalin lies about 43 kilometers (26 mi) to the north of Hokkaidō, and to the east and northeast are the Kuril Islands, which are administered by Russia, though the four most southerly are claimed by Japan. Hokkaidō was formerly known as ''Ezo'', ''Yezo'', ''Yeso'', or ''Yesso''. Nussbaum, Louis-Frédéric. (2005). "Hokkaidō" in Although there were Japanese settlers who ruled the southern tip of the island since the 16th century, Hokkaido was considered foreign territory that was inhabited by the indigenous people of the island, known as the Ainu people.

Bird Song
Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs are the bird sounds that are melodious to the human ear. In ornithology and birding, songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations). Definition The distinction between songs and calls is based upon complexity, length, and context. Songs are longer and more complex and are associated with territory and courtship and mating, while calls tend to serve such functions as alarms or keeping members of a flock in contact. Other authorities such as Howell and Webb (1995) make the distinction based on function, so that short vocalizations, such as those of pigeons, and even non-vocal sounds, such as the drumming of woodpeckers and the "winnowing" of snipes' wings in display flight, are considered songs. Still others require song to have syllabic diversity and temporal regularity akin to the repetitive and transformative patte ...

Birding World
''Birding World'' was a monthly birding magazine published in the United Kingdom. It was the magazine of the Bird Information Service, based at Cley next the Sea, Norfolk. With the publication of issue No. 26/12 in January 2014, ''Birding World'' magazine ceased publication.

Grey-streaked Flycatcher
The grey-streaked flycatcher or grey-spotted flycatcher (''Muscicapa griseisticta'') is a small passerine bird breeding in the eastern Palearctic belonging to the genus ''Muscicapa'' in the Old World flycatcher family Muscicapidae. The species was first described by Robert Swinhoe in 1861. It is a slender, long-winged bird with a length of 13 to 15 cm. It is mainly grey brown above and white below. The breast and flanks are heavily streaked with grey. There is a narrow white bar on the wing and a pale patch between the bill and eye. The bill and feet are black. The eye is large and there is a white eye-ring. The adult male and female are alike but juvenile birds differ in having white spots and dark scaling on the upperparts. It breeds in the vast coniferous forests in north-east China, North Korea and south-east Siberia including Sakhalin and Kamchatka. In spring and autumn it migrates through eastern and southern China, South Korea, Japan and Taiwan. In winter it occurs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asian Brown Flycatcher
The Asian brown flycatcher (''Muscicapa dauurica'') is a small passerine bird in the flycatcher family Muscicapidae. The word ''Muscicapa'' comes from the Latin ''musca'', a fly and ''capere'', to catch. The specific ''dauurica'' refers to Dauria, an area of south-eastern Siberia named after a local nomadic tribe. This is an insectivorous species which breeds in Japan, eastern Siberia and the Himalayas. It is migratory and winters in tropical southern Asia from southern India and Sri Lanka east to Indonesia. The correct specific epithet for this species is disputed. Description This species is long, including the cocked tail. It is similar in shape to the larger spotted flycatcher, but is relatively longer-tailed. The dark bill is relatively large and broad-based. The adult has grey-brown upperparts, which become greyer as the plumage ages, and whitish underparts with brown-tinged flanks. Young birds have scaly brown upperparts, head and breast.

Juvenile (organism)
A juvenile is an individual organism that has not yet reached its adult form, sexual maturity or size. Juveniles can look very different from the adult form, particularly in colour, and may not fill the same niche as the adult form. In many organisms the juvenile has a different name from the adult (see List of animal names). Some organisms reach sexual maturity in a short metamorphosis, such as eclosion in many insects. For others, the transition from juvenile to fully mature is a more prolonged process—puberty in humans and other species, for example. In such cases, juveniles during this transformation are sometimes called subadults. Many invertebrates, on reaching the adult stage, are fully mature and their development and growth stops. Their juveniles are larvae or nymphs. In vertebrates and some invertebrates (e.g. spiders), larval forms (e.g. tadpoles) are usually considered a development stage of their own, and "juvenile" refers to a post-larval stage that is not full ...
