Dwarf Sparrowhawk
The dwarf sparrowhawk (''Accipiter nanus''), also known as the small sparrowhawk, is a species of bird of prey in the family Accipitridae. It is endemic to Indonesian islands of Sulawesi and Buton. Its natural habitats are subtropical or tropical moist montane forests and to a lesser degree lowland forests. It closely resembles the fellow Wallacean vinous-breasted sparrowhawk, but is still thought to be most closely related to besra.James Ferguson-Lees & David Christie (2005). Raptors of the world. Christopher Helm. London, UK. All this makes it rather difficult to identify and thus possibly under-recorded. It is one of the smallest members of its family (length approximately 25 cm/10in). Hunts insects and small birds. It is threatened by habitat loss. There are not many verified recordings of this species, but it is known to occur at least in Lore Lindu National Park Lore Lindu National Park is a protected area of forest on the Indonesian island of Sulawesi, in the provi ...

Birds Described In 1897
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. Bird ...

Accipiter
''Accipiter'' is a genus of Bird of prey, birds of prey in the family Accipitridae. With 51 recognized species it is the most diverse genus in its family. Most species are called goshawks or sparrowhawks, although almost all New World species (excepting the northern goshawk) are simply known as hawks. They can be anatomically distinguished from their relatives by the lack of a coracoid, procoracoid foramen. Two small and aberrant species usually placed here do possess a large procoracoid foramen and are also distinct as regards DNA sequence. They may warrant separation in the old genus ''Hieraspiza''.Olson (2006) Extant accipiters range in size from the little sparrowhawk (''A. minullus''), in which the smallest males measure long, span across the wings and weigh , to the northern goshawk (''A. gentilis''), in which the largest females measure long, span across the wings, and weigh . These birds are slender with short, broad, rounded wings and a long tail which helps them mane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

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 ...

Besra
The besra (''Accipiter virgatus''), also called the besra sparrowhawk, is a bird of prey in the family Accipitridae. The besra is a widespread resident breeder in dense forests throughout southern Asia, ranging from the Indian subcontinent eastwards across Southeast Asia and into East Asia. It nests in trees, building a new nest each year. It lays 2 to 5 eggs. This bird is a medium-sized raptor (29 to 36 cm) with short broad wings and a long tail, both adaptations to fast maneuvering through dense vegetation. The normal flight of this species is a characteristic "flap–flap–glide". This species is like a darker version of the widespread shikra with darker upperparts, strongly barred underwing, broader gular stripe and thin long legs and toes. The adult male besra has dark blue-grey upperparts, and is white, barred reddish brown below. The larger female is browner above than the male. The juvenile is dark brown above and white, barred with brown below. In all plu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wallacea
Wallacea is a biogeographical designation for a group of mainly Indonesian islands separated by deep-water straits from the Asian and Australian continental shelves. Wallacea includes Sulawesi, the largest island in the group, as well as Lombok, Sumbawa, Flores, Sumba, Timor, Halmahera, Buru, Seram, and many smaller islands. The islands of Wallacea lie between the Sunda Shelf (the Malay Peninsula, Sumatra, Borneo, Java, and Bali) to the west, and the Sahul Shelf including Australia and New Guinea to the south and east. The total land area of Wallacea is . Geography Wallacea is defined as the series of islands stretching between the two continental shelves of Sunda and Sahul, but excluding the Philippines. Its eastern border (separating Wallacea from Sahul) is represented by a zoogeographical boundary known as Lydekker's Line, while the Wallace Line (separating Wallacea from Sunda) defines its western border. The Weber Line is the midpoint, at which Asian and Australian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Of Prey
Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and other smaller birds). In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding both piscivorous predators such as storks, herons, gulls, skuas, penguins and kingfishers, as well as primarily insectivorous birds such as passerine birds (e.g. shrikes) and birds like nightjars and frogmouths.

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
