Blue-black Kingfisher
The blue-black kingfisher (''Todiramphus nigrocyaneus'') is a species of bird in the family Alcedinidae.A medium-sized kingfisher of mangroves and forested streams in the lowlands. It is found in New Guinea and offshore islands of Salawati, Batanta and Yapen. It is considered rare (although it may be more common in Papua) and declining with threats being logging of lowland swamp forests and declining water quality. Description The blue-black kingfisher is 23 cm (9.1 inches) long and weighs 51–57 grams (1.8–2.0 ounces). Black face, blue crown and bright white throat are characteristic. Underparts of males vary geographically, some with rufous or dark bellies and a white crescent. Females have white belly. Perches in the understory, scanning below for its prey of fish or crabs. Very difficult to see. Somewhat similar to Azure Kingfisher The azure kingfisher (''Ceyx azureus'') is a small kingfisher in the river kingfisher subfamily, Alcedininae.Pizzey, Graham and Doyle, Roy ...

Alfred Russel Wallace
Alfred Russel Wallace (8 January 1823 – 7 November 1913) was a British naturalist, explorer, geographer, anthropologist, biologist and illustrator. He is best known for independently conceiving the theory of evolution through natural selection. His 1858 paper on the subject was published that year alongside extracts from Charles Darwin's earlier writings on the topic. It spurred Darwin to set aside the "big species book" he was drafting, and quickly write an abstract of it, published in 1859 as ''On the Origin of Species''. Wallace did extensive fieldwork, first in the Amazon River basin. He then did fieldwork in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia. He was considered the 19th century's leading expert on the geographical di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
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. B ...

Batanta
Batanta is one of the four major islands in the Raja Ampat Islands in Southwest Papua province, Indonesia. Its area is 453 km² and its highest point is 1184 m. The Pitt Strait separates it from Salawati, while the Dampier Strait separates it from Waigeo. Dampier Strait is named for the English explorer William Dampier. In 1759 Captain William Wilson sailing in the East Indiaman ''Pitt'' navigated these waters and named the channel between Batanta and Salawati Pitt Strait, after his vessel.

Azure Kingfisher
The azure kingfisher (''Ceyx azureus'') is a small kingfisher in the river kingfisher subfamily, Alcedininae.Pizzey, Graham and Doyle, Roy. (1980) ''A Field Guide to the Birds of Australia.'' Collins Publishers, Sydney. Description The azure kingfisher measures in length, and the male weighs while the female is slightly heavier at . It is a very colourful bird, with deep blue to azure back, a large white to buff spot on the side of the neck and throat, rufous-buff with some blue-violet streaks on the breast and flanks.

Taxonomy The subspecies (see box at right) differ only in minor details: compared with the nominate subspecies ''Ceyx azureus azureus'', ''C. a. ruficollaris'' is smaller, brighter, and has more blue on t ...

Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...
