Hierococcyx Pectoralis
The Philippine hawk-cuckoo (''Hierococcyx pectoralis'') is a bird belonging to the cuckoo family. It is found only in the Philippines. It was formerly classified as a subspecies of Hodgson's hawk-cuckoo but is now its own species. Description and taxonomy It is a medium-sized cuckoo, about 29 centimetres in length. The adult is dark-grey above and white below with a pale rufous breast and upper belly. The tail has three or four black and buff bars, a broad black band near the tip and a pale rufous tip. There is a bare yellow ring around the eye. The legs and feet are also yellow and the bill is black and olive. Immature birds have rufous barring above and brown streaks below. The bird has a high-pitched call of five to seven notes. The call lasts for about 1.5 seconds and is repeated up to 10 times, becoming louder and faster. It was formerly classified as a subspecies of Hodgson's hawk-cuckoo (''H. fugax'') but is now commonly treated as a separate species based on differe ...

Jean Cabanis
Jean Louis Cabanis (8 March 1816 – 20 February 1906) was a German ornithologist. He worked at the bird collections of the Natural History Museum in Berlin becoming its first curator of birds in 1850. He founded the ''Journal für Ornithologie'' in 1853''.'' Biography Cabanis was born in Berlin to an old Huguenot family who had moved from France. His father Benoit-Jean (1774–1838) and mother Maria Luise (1783–1849) both came from families that were in the textile industry. Little is known of his early life. He studied at the University of Berlin from 1835 to 1839, and then travelled to North America, working as a museum assistant in Carolina. He returned in 1841 with a large natural history collection. He was assistant at the Natural History Museum, Berlin, Natural History Museum of Berlin (which was at the time the Berlin University Museum) and in 1850 he became the curator of birds, taking over from Martin Lichtenstein. Charles Lucien Bonaparte had offered him a positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slash-and-burn
Slash-and-burn agriculture is a form of shifting cultivation that involves the cutting and burning of plants in a forest or woodland to create a Field (agriculture), field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the Biomass (ecology), biomass is burned, resulting in a nutrient-rich layer of ash which makes the Soil fertility, soil fertile, as well as temporarily eliminating weed and pest species. After about three to five years, the plot's productivity decreases due to depletion of nutrients along with weed and pest invasion, causing the farmers to abandon the field and move to a new area. The time it takes for a swidden to recover depends on the location and can be as little as five years to more than twenty years, after which the plot can be slashed and burned again, repeating the cycle. In Bangladesh and India, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1863
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 furth ...

Endemic Birds Of The Philippines
This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. Patterns of endemism The Wild Bird Club of the Philippines has a checklist of the birds of the Philippines which follows the IOC World Bird List. Of these 260 bird species endemic to the Philippines. Many of these are restricted to specific islands, particularly Luzon, Mindanao, and Palawan.''A Guide to the Birds of the Philippines'', Robert S. Kennedy et al., Oxford University Press, 2013. The number of endemic species recognized in the Philippines has increased in recent years, mainly due to " splits" of species and, to a much lesser extent, due to the discovery of previously unknown species. An example of splitting is the division of the erstwhile species Philippine hawk-owl (''Ninox scutulata'') into seven species, now called by the name of this-or-that boobook (Luzon boobook, Mindoro boobook, etc. see the list below). Another example is the split of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hierococcyx
''Hierococcyx'' or hawk-cuckoos is a genus of birds in the family Cuculidae. They are distributed in South, Southeast, and East Asia. The resemblance to hawks gives this group the generic name of hawk-cuckoos. They are known to vocalize at their breeding grounds, making identification based on calls easy. It is sometimes included in the genus ''Cuculus''. It's similarity to hawks gave rise to an ancient belief that cuckoos transformed themself into hawks during the winter months, when cuckoos disappeared from Europe. Mimicry Hawk-cuckoos closely resemble accipiters in terms of appearance, an elongated body with long wings and tail, greyish or brownish upperparts with paler barred upperparts, as well as their swift direct flight. Apart from shape and colour, underpart barring tend to increase alarm in small parts. This form of batesian mimicry makes the cuckoo look dangerous to the host, reducing host agression or Mobbing (animal behavior), resulting in more opportunities fo ...

Illegal Logging
Illegal logging is the harvest, transportation, purchase, or sale of timber in violation of laws. The harvesting procedure itself may be illegal, including using corrupt means to gain access to forests; extraction without permission, or from a protected area; the cutting down of protected species; or the extraction of timber in excess of agreed limits. Illegal logging is a driving force for a number of environmental issues such as deforestation, soil erosion and biodiversity loss which can drive larger-scale environmental crises such as climate change and other forms of environmental degradation. Illegality may also occur during transport, such as illegal processing and export (through smuggling, fraudulent declaration to customs); the tax avoidance, avoidance of taxes and other charges, and fraudulent certification. These acts are often referred to as "wood laundering". Illegal logging is driven by a number of economic forces, such as demand for raw materials, land grabbing and ...
