Sentinel-2
Sentinel-2 is an Earth observation mission from the Copernicus Programme that systematically acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters. The mission is currently a constellation with two satellites, Sentinel-2A and Sentinel-2B; a third satellite, Sentinel-2C, is currently undergoing testing in preparation for launch in 2024. The mission supports a broad range of services and applications such as agricultural monitoring, emergencies management, land cover classification or water quality. Sentinel-2 has been developed and is being operated by the European Space Agency, and the satellites were manufactured by a consortium led by Airbus Defence and Space in Friedrichshafen. Overview The Sentinel-2 mission has the following key characteristics: * Multi-spectral data with 13 bands in the visible, near infrared, and short wave infrared part of the spectrum * Systematic global coverage of land surfaces from 56° S to 84°&nb ...

Egret
Egrets ( ) are herons, generally long-legged wading birds, that have white or buff plumage, developing fine plumes (usually milky white) during the breeding season. Egrets are not a biologically distinct group from herons and have the same build. Biology Many egrets are members of the genera ''Egretta'' or '' Ardea'', which also contain other species named as herons rather than egrets. The distinction between a heron and an egret is rather vague, and depends more on appearance than biology. The word "egret" comes from the French word ''aigrette'' that means both "silver heron" and "brush", referring to the long, filamentous feathers that seem to cascade down an egret's back during the breeding season (also called "egrets"). Several of the egrets have been reclassified from one genus to another in recent years; the great egret, for example, has been classified as a member of either ''Casmerodius'', ''Egretta'', or ''Ardea''. In the 19th and early part of the 20th centuries, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caspian Roach
The Caspian roach (''Rutilus caspicus'') is a species of roach fish living in the Caspian Sea. The Caspian roach can be distinguished from other roaches by its laterally compressed body, silvery grey iris, rounded snout and grey pectoral pelvic and anal fins with dark margins. The Caspian roach is semi- anadromous and inhabits mostly shallow coastal waters. It enters Volga, Ural, Emba, Terek and Kura drainages for spawning. Newer research however suggests that ''R. caspicus'' is part of a more widely distributed species or roach, whose range extends to Siberia. The proper name of that species is ''Rutilus lacustris''.Levin, B.A., Simonov, E.P., Ermakov, O.A., Levina, M.A., Interesova, E.A., Kovalchuk, O.M., Malinina, Y.A., Mamilov, N.S., Mustafayev, N.J., Pilin, D.V., Pozdeev, I.V., Prostakov, N.I., Roubenyan, H.R., Titov, S.V. & Vekhov, D.A.

Pallas's Gull
Pallas's gull (''Ichthyaetus ichthyaetus''), also known as the great black-headed gull, is a large bird species. As is the case with many gulls, it has traditionally been placed in the genus ''Larus''. The scientific name is from Ancient Greek. ''Ichthyaetus'' is from ''ikhthus'', "fish", and ''aetos'', "eagle". Distribution This species breeds in colonies in marshes and islands from southern Russia to Mongolia. It is migratory, wintering in the eastern Mediterranean, Arabia and India. This gull nests on the ground, laying between two and four eggs. It occurs in western Europe only as a rare vagrant. In Great Britain a recent review left a single occurrence in 1859 as the only acceptable record of this bird. The species also occurs as a vagrant in differing parts of the Indian Ocean, south of its normal range, and along the northern and eastern coasts of Africa, where it visits annually on an irregular basis.

Little Bustard
The little bustard (''Tetrax tetrax'') is a bird in the bustard family, the only member of the genus ''Tetrax''. The genus name is from Ancient Greek and refers to a gamebird mentioned by Aristophanes and others. Distribution It breeds in Southern Europe and in Western and Central Asia. Southernmost European birds are mainly resident, but other populations migrate further south in winter. The central European population once breeding in the grassland of Hungary became extinct several decades ago. The species is declining due to habitat loss throughout its range. It used to breed more widely, for example ranging north to Poland occasionally. It is only a very rare vagrant to Great Britain despite breeding in France. On 20 December 2013, the Cypriot newspapers 'Fileleftheros' and 'Politis', as well as news website 'SigmaLive', reported the discovery of a dead little bustard in the United Nations Buffer Zone. The bird had been shot by poachers hunting illegally in the zone. The sho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demoiselle Crane
The demoiselle crane (''Grus virgo'') is a species of crane found in central Eurosiberia, ranging from the Black Sea to Mongolia and North Eastern China. There is also a small breeding population in Turkey. These cranes are migratory birds. Birds from western Eurasia will spend the winter in Africa while the birds from Asia, Mongolia and China will spend the winter in the Indian subcontinent. The bird is symbolically significant in the culture of India, where it is known as ''Koonj'' or ''Kurjaa''. Description The demoiselle is long, tall and has a wingspan. It weighs .

Whooper Swan
The whooper swan ( /ˈhuːpə(ɹ) swɒn/) (''Cygnus cygnus''), also known as the common swan, pronounced ''hooper swan'', is a large northern hemisphere swan. It is the Eurasian counterpart of the North American trumpeter swan, and the type species for the genus '' Cygnus''. Taxonomy Francis Willughby and John Ray's ''Ornithology'' of 1676 referred to this swan as "the Elk, Hooper, or wild Swan". It was one of the many bird species originally described by Carl Linnaeus in the 1758 10th edition of his ''Systema Naturae'', where it was given the binomial name of ''Anas cygnus''. The species name is from ''cygnus'', the Latin for "swan". Description The whooper swan is similar in appearance to Bewick's swan. It is larger, however, at a length of and a wingspan of . The weight is typically in the range of , with an average of for males and for females. The verified record mass was for a wintering male from Denmark. It is considered to be amongst the heaviest flying birds. Amon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glossy Ibis
The glossy ibis (''Plegadis falcinellus'') is a water bird in the order Pelecaniformes and the ibis and spoonbill family Threskiornithidae. The scientific name derives from Ancient Greek ''plegados'' and Latin, ''falcis'', both meaning "sickle" and referring to the distinctive shape of the bill. Distribution This is the most widespread ibis species, breeding in scattered sites in warm regions of Europe, Asia, Africa, Australia, and the Atlantic and Caribbean regions of the Americas. It is thought to have originated in the Old World and spread naturally from Africa to northern South America in the 19th century, from where it spread to North America. The glossy ibis was first found in the New World in 1817 (New Jersey). Audubon saw the species just once in Florida in 1832. It expanded its range substantially northwards in the 1940s and to the west in the 1980s. This species is migratory; most European birds winter in Africa, and in North America birds from north of the Carolinas w ...
