Water Pollution
Water pollution (or aquatic pollution) is the contamination of water bodies, usually as a result of human activities, so that it negatively affects its uses. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants are introduced into these water bodies. Water pollution can be attributed to one of four sources: sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. It can be grouped into surface water pollution (either fresh water pollution or marine pollution) or groundwater pollution. For example, releasing inadequately treated wastewater into natural waters can lead to degradation of these aquatic ecosystems. Water pollution can also lead to water-borne diseases for people using polluted water for drinking, bathing, washing or irrigation. Water pollution reduces the ability of the body of water to provide the ecosystem services (such as drinking water) that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Goldeneye
The common goldeneye or simply goldeneye (''Bucephala clangula'') is a medium-sized sea duck of the genus ''Bucephala'', the goldeneyes. Its closest relative is the similar Barrow's goldeneye. The genus name is derived from the Ancient Greek ''boukephalos'' ("bullheaded", from ''bous'', "bull " and ''kephale'', "head"), a reference to the bulbous head shape of the bufflehead. The species name is derived from the Latin ''clangere'' ("to resound"). Common goldeneyes are aggressive and territorial ducks, and have elaborate courtship displays. Description Adult males ranges from and weigh approximately , while females range from and weigh approximately . The common goldeneye has a wingspan of 30.3-32.7 in (77-83 cm). The species is named for its golden-yellow eye. Adult males have a dark head with a greenish gloss and a circular white patch below the eye, a dark back and a white neck and belly. Adult females have a brown head and a mostly grey body. Their legs and feet are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tufted Duck
The tufted duck or tufted pochard (''Aythya fuligula'') is a small diving duck with a population of close to one million birds, found in northern Eurasia. The scientific name is derived from Ancient Greek '' aithuia'', an unidentified seabird mentioned by authors including Hesychius and Aristotle, and ''Latin'' ''fuligo'' "soot" and ''gula'' "throat". Description The adult male is all black except for white flanks and a blue-grey bill with gold-yellow eyes, along with a thin crest on the back of its head. It has an obvious head tuft that gives the species its name. The adult female is brown with paler flanks, and is more easily confused with other diving ducks. In particular, some have white around the bill base which resembles the scaup species, although the white is never as extensive as in those ducks. The females' call is a harsh, growling "karr", mostly given in flight. The males are mostly silent but they make whistles during courtship based on a simple "wit-oo". The onl ...

Eurasian Teal
The Eurasian teal (''Anas crecca''), common teal, or Eurasian green-winged teal is a common and widespread duck that breeds in temperate Eurosiberia and migrates south in winter. The Eurasian teal is often called simply the teal due to being the only one of these small dabbling ducks in much of its range. The bird gives its name to the blue-green colour teal. It is a highly gregarious duck outside the breeding season and can form large flocks. It is commonly found in sheltered wetlands and feeds on seeds and aquatic invertebrates. The North American green-winged teal (''A. carolinensis'') was formerly (and sometimes is still) considered a subspecies of ''A. crecca''. Taxonomy The Eurasian teal belongs to the "true" teals, a group of small ''Anas'' dabbling ducks closely related to the mallard (''A. platyrhynchos'') and its relatives; that latter group in fact seems to have evolved from a true teal. It forms a superspecies with the green-winged teal and the speckled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Shoveler
The northern shoveler (; ''Spatula clypeata''), known simply in Britain as the shoveler, is a common and widespread duck. It breeds in northern areas of Europe and across the Palearctic and across most of North America, wintering in southern Europe, the Indian subcontinent, Southeast Asia, Central, the Caribbean, and northern South America. It is a rare vagrant to Australia. In North America, it breeds along the southern edge of Hudson Bay and west of this body of water, and as far south as the Great Lakes west to Colorado, Nevada, and Oregon. The northern shoveler is one of the species to which the ''Agreement on the Conservation of African-Eurasian Migratory Waterbirds'' (AEWA) applies. The conservation status of this bird is Least Concern. Taxonomy The northern shoveler was first formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. He introduced the binomial name ''Anas clypeata''. A molecular phylogentic study ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mallard
The mallard () or wild duck (''Anas platyrhynchos'') is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa, and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. Males have purple patches on their wings, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is long, of which the body makes up around two-thirds the length. The wingspan is and the bill is long. It is often slightly heavier than most other dabbling ducks, weighing . Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varyi ...

Gadwall
The gadwall (''Mareca strepera'') is a common and widespread dabbling duck in the family Anatidae. Taxonomy The gadwall was first described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. DNA studies have shown that it is a sister species with the falcated duck; the two are closely related to the three species of wigeons, and all of them have been assigned to the genus ''Mareca''. There are two subspecies: * ''M. s. strepera'', the common gadwall, described by Linnaeus, is the nominate subspecies. * ''M. s. couesi'', Coues's gadwall, extinct 1874, was formerly found only on Teraina, a coral atoll in the Pacific Ocean. The specific name ''strepera'' is Late Latin for "noisy". The etymology of the word ''gadwall'' is not known, but the name has been in use since 1666. Description The gadwall is long with a wingspan. The male is slightly larger than the female, weighing on average against her . The breeding male is patterned grey, with a black re ...
