Treeswift
Treeswifts or crested swifts are a family, the Hemiprocnidae, of aerial near passerine birds, closely related to the true swifts. The family contains a single genus, ''Hemiprocne'', with four species. They are distributed from India and Southeast Asia through Indonesia to New Guinea and the Solomon Islands. Treeswifts are small to medium-sized swifts, ranging in length from 15 to 30 cm. They have long wings, with most of the length coming from the length of the primaries; their arms are actually quite short. They visibly differ from the other swifts in matters of plumage, which is softer, and they have crests or other facial ornaments, and long, forked tails. Anatomically they are separated from the true swifts by skeletal details in the cranium and palate, the anatomy of the tarsus, and a nonreversible hind toe that is used for perching on branches (an activity in which true swifts are unable to engage). The males have iridescent mantle plumage. They also have diastataxic wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whiskered Treeswift
The whiskered treeswift (''Hemiprocne comata'') is a species of bird in the family Hemiprocnidae. It is the smallest of 4 species in genus ''Hemiprocne'' and is found in Brunei, Indonesia, Malaysia, Myanmar, the Philippines, Singapore, and Thailand. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical mangrove forest, and subtropical or tropical moist montane forest Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, fall as elevation increases, causing the ecosystem to stratify. This stratification is .... Description Medium, unique white elongated 'whiskers' above and below eye, shaggy crest, deeply forked tail, sexes similar. Male lores black; two elongated white 'whiskers', one above eye from forehead extending past nape; ear chestnut; rest of head and throat, tail, upper and underwing coverts, and primaries dark metallic ...

Crested Treeswift
The crested treeswift (''Hemiprocne coronata'') is a species of tree swift. It was for some time considered the same species as its eastern relative, the gray-rumped treeswift (''Hemiprocne longipennis''), but they do not interbreed where their ranges overlap. It is distinct in flight, with long, bowed wings and a deeply forked tail that usually appears narrow and pointed. Description The crested treeswift is a large slender bird at length. This species is dove grey above and white below. The long swept-back wings are a darker grey above. This treeswift has a crest and a long, deeply forked tail. The adult male has orange cheeks and ear coverts with a narrow streak of white under the eye and a trace of a white supercilium. The female also has a thin white stripe below the eye running below the grey cheek and ear coverts. Young birds have a dark grey head and wings but the feathers are edged in white and the rest of the soft plumage is much streakier than that of the adults. The ...

Moustached Treeswift (Hemiprocne Mystacea)
The moustached treeswift (''Hemiprocne mystacea'') is a species of bird in the family Hemiprocnidae. It is found in the northern Moluccas, New Guinea, Bismarck and the Solomon Islands archipelagos. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, and subtropical or tropical moist montane forest Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, fall as elevation increases, causing the ecosystem to stratify. This stratification is ...s. The Moustached treeswift (Hemiprocne mystacea), a species of bird in the family Hemiprocnidae, is known for its remarkable aerial foraging abilities. Recent scientific studies, such as Rohwer and Wang's quantitative analysis in 2010, have highlighted the unique feather replacement patterns that contribute to its agile flight and successful prey capture.

Hemiprocne Longipennis
The grey-rumped treeswift (''Hemiprocne longipennis'') is a species of bird in the Hemiprocnidae family. Currently, four extant species are placed in the family. Like the other members of the Hemiprocnidae, this species is closely related to true swifts, but unlike true swifts, the treeswifts are arboreal in nature, often seen perched on trees and high-tension power transmission lines, and on pylons. When perched, the wing tips cross over the tail. This species is commonly found in peninsular Malaysia, but has an extremely large range with limited information about the population trend,.Jeyarajasingam. A. and Pearson. A. 2012. A Field Guide to the Birds of Peninsular Malaysia and Singapore. Oxford University press Description Adult males have a distinct dark grey throat and chest contrasting with a white belly. Ear coverts are dull orange red/chestnut colored. Adult females lack the dull orange-red/chestnut coloration on the ear coverts. When perched, the wing tips cross over ac ...

Apodiformes
The Apodiformes is an Order (biology), order, or Taxonomy, taxonomic grouping, of Bird, birds which traditionally contained three living Family (biology), families—the Swift (bird), Apodidae (swifts), the Treeswift, Hemiprocnidae (treeswifts), and the Hummingbird, Trochilidae (hummingbirds); however, in the Sibley-Ahlquist taxonomy, this order is elevated to the superorder Apodimorphae, in which hummingbirds are separated into a new order, the Trochiliformes. With nearly 450 species identified to date, it is the most diverse order of birds after the passerine, Passeriformes (the "perching" birds). Description, etymology and taxonomy As the name ''apodiforme''—meaning "footless" in Greek language, Greek—suggests, the legs of hummingbirds, swifts and treeswifts (or 'crested' swifts) are rather small and offer limited functional uses, aside from perching; their feet are covered with bare skin, rather than the Scute, scutes seen on many birds. Another commonality amongst Apodif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swift (bird)
The Apodidae, or swifts, form a family of highly aerial birds. They are superficially similar to swallows, but are not closely related to any passerine species. Swifts are placed in the order Apodiformes along with hummingbirds. The treeswifts are closely related to the true swifts, but form a separate family, the Hemiprocnidae. Resemblances between swifts and swallows are due to convergent evolution, reflecting similar life styles based on catching insects in flight. The family name, Apodidae, is derived from the Greek ἄπους (''ápous''), meaning "footless", a reference to the small, weak legs of these most aerial of birds.Jobling (2010) pp. 50–51.Kaufman (2001) p. 329. The tradition of depicting swifts without feet continued into the Middle Ages, as seen in the heraldic martlet. Taxonomy Taxonomists have long classified swifts and treeswifts as relatives of the hummingbirds, a judgment corroborated by the discovery of the Jungornithidae (apparently swift-like hum ...

Mangrove
A mangrove is a shrub or tree that grows mainly in coastal saline water, saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal rivers. They have particular adaptations to take in extra oxygen and remove salt, allowing them to tolerate conditions that kill most plants. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse due to convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
