Flycatcher-shrike
The flycatcher-shrikes are two species of small Asian passerine bird belonging to the genus ''Hemipus''. They are now usually placed in the Vangidae. Description They are in length.Robson, Craig (2002) ''A Field Guide to the Birds of South-east Asia'', New Holland, London. They are slender birds with fairly long wings and tails. The beak, bill and feet are black.MacKinnon, John & Phillipps, Karen (1993) ''A Field Guide to the Birds of Borneo, Sumatra, Java and Bali'', Oxford University Press, Oxford. The plumage is dark above and pale below with white on the rump. The bar-winged flycatcher-shrike has a large white patch on the wing which the black-winged flycatcher-shrike lacks. Distribution and range They are found in broad-leaved forest, forest edge and secondary forest in southern Asia. Both species have large ranges and are not considered to be threatened species, threatened. The bar-winged flycatcher-shrike occurs in the Indian Subcontinent, south-west China, mainland Sout ...

Black-winged Flycatcher-shrike
The black-winged flycatcher-shrike (''Hemipus hirundinaceus'') is a species of bird in the flycatcher-shrike genus, ''Hemipus''. It is usually placed in the Vangidae. It is found in the Malay Peninsula and the Greater Sunda Islands. Its natural habitats are lowland forests and sometimes swamps and mangroves. The International Union for Conservation of Nature (IUCN) has assessed it as being of least concern. Taxonomy Thomas Horsfield described this species as ''Muscicapa obscura'' in 1821, and it was later transferred to the genus ''Hemipus'', as ''Hemipus obscurus''. Because ''Muscicapa obscura'' was an unavailable name, the name ''Muscicapa hirundinacea'' published by Coenraad Jacob Temminck in 1822 was used, making the name ''Hemipus hirundinaceus''. The IOC World Bird List transferred the genus ''Hemipus'' from Campephagidae, the cuckooshrikes, to Tephrodornithidae, the woodshrikes, because it was found to be closely related to ''Tephrodornis'' in 2006.

Bar-winged Flycatcher-shrike
The bar-winged flycatcher-shrike (''Hemipus picatus'') is a small passerine bird usually placed in the Vangidae. It is found in the forests of tropical southern Asia from the Himalayas and hills of southern India to Indonesia. Mainly insectivorous it is found hunting in the mid-canopy of forests, often joining mixed-species foraging flocks. They perch upright and have a distinctive pattern of black and white, males being more shiny black than the females. In some populations the colour of the back is brownish while others have a dark wash on the underside. Description The bar-winged flycatcher-shrike is black capped with black wings that contrast with the white of the body. A white slash across the wing and a white rump stand out in contrast. They sit upright on branches, flying around to Gleaning (birds), glean insects. The nostril is hidden by hairs and the upper mandible of the beak has a curved tip. Males are velvety black while females tend to be greyish brown but the patte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vangidae
The family Vangidae (from ''vanga'', Malagasy language, Malagasy for the hook-billed vanga, ''Vanga curvirostris'') comprises a group of often shrike-like medium-sized birds distributed from Asia to Africa, including the vangas of Madagascar to which the family owes its name. Many species in this family were previously classified elsewhere in other families. Recent molecular techniques made it possible to assign these species to Vangidae, thereby solving several taxonomic enigmas. The family contains 40 species divided into 21 genera. Taxonomy In addition to the small set of Malagasy species traditionally called the vangas, Vangidae includes some Asian groups: the woodshrikes (''Tephrodornis''), flycatcher-shrikes (''Hemipus'') and philentomas. Vangidae belongs to a clade of corvid birds that also includes bushshrikes (Malaconotidae), ioras (Aegithinidae) and the Australian butcherbirds, magpies and currawongs (Cracticidae) and woodswallows (Artamidae), which has been defined ...

Bali
Bali (English:; Balinese language, Balinese: ) is a Provinces of Indonesia, province of Indonesia and the westernmost of the Lesser Sunda Islands. East of Java and west of Lombok, the province includes the island of Bali and a few smaller offshore islands, notably Nusa Penida, Nusa Lembongan, and Nusa Ceningan to the southeast. The provincial capital, Denpasar, is the List of Indonesian cities by population, most populous city in the Lesser Sunda Islands and the second-largest, after Makassar, in Eastern Indonesia. Denpasar metropolitan area is the extended metropolitan area around Denpasar. The upland town of Ubud in Greater Denpasar is considered Bali's cultural centre. The province is Indonesia's main tourist destination, with a significant rise in Tourism in Bali, tourism since the 1980s, and becoming an Indonesian area of overtourism. Tourism-related business makes up 80% of the Bali economy. Bali is the only Hinduism in Indonesia, Hindu-majority province in Indonesia, ...

Forest Canopy
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Shade trees normally have a dense canopy that blocks light from lower growing plants. Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs suspended on vines or hot-air dirigibles, among others. Modern technology, including adapted mountaineering gear, has made canopy observation significant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mixed-species Foraging Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock (birds), flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the Americas, American tropics packs of foraging golden-crowned warblers might play the same role.

Bird Nest
A bird nest is the spot in which a bird lays and Avian incubation, incubates its Bird egg, eggs and raises its young. Although the term popularly refers to a specific structures built by animals, 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 ...

Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilization, fertilized egg cell (a zygote) and to egg incubation, 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, vertebrates (excluding live-bearing mammals), and Mollusca, 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 eggshell, 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 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malay Peninsula
The Malay Peninsula is located in Mainland Southeast Asia. The landmass runs approximately north–south, and at its terminus, it is the southernmost point of the Asian continental mainland. The area contains Peninsular Malaysia, Southern Thailand, and the southernmost tip of Myanmar (Kawthaung District, Kawthaung). The island country of Singapore also has historical and cultural ties with the region. The Titiwangsa Mountains are part of the Tenasserim Hills system and form the backbone of the peninsula and the southernmost section of the central cordillera, which runs from Tibet through the Kra Isthmus, the peninsula's narrowest point, into the Malay Peninsula. The Strait of Malacca separates the Malay Peninsula from the Indonesian island of Sumatra, and the south coast is separated from the island of Singapore by the Straits of Johor. Etymology The Malay term ''Tanah Melayu'' is derived from the word ''Tanah'' (land) and ''Melayu'' (Malays (ethnic group), Malays), thus ...
