Shalkar () is a brackish lake in Shalkar District, Aktobe Region, Kazakhstan. Shalkar city lies by the northeastern lakeshore. The lake provides water to the city and adjacent railway stations.Google Earth Geography Shalkar is located km to the NNW of the Aral Sea. It lies in the Shalkar Basin, a wide tectonic depression between the Mugalzhar Hills to the west and the Barsuki Desert to the east. The Kauylzhyr river flows from the north into the northern end. The lake presently consists in a roughly oval string of residual pools with an expanse of dry terrain at the center. The pools forming the lake freeze on average by early November and thaw in late March to early April. The ice thickness in the middle of the winter reaches between and . History Shalkar is a drying lake. It had been larger and deeper until the 20th century. In 1937 a stone and concrete dam was built in order to decrease the salinity of the northern part of the lake. This dam divided lake Shalkar into two sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sentinel-2
Sentinel-2 is an Earth observation mission from the Copernicus Programme that acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters. The mission's Sentinel-2A and Sentinel-2B satellites were joined in orbit in 2024 by a third, Sentinel-2C, and in the future by Sentinel-2D, eventually replacing the A and B satellites, respectively. The mission supports services and applications such as agricultural monitoring, emergencies management, land cover classification, and water quality. Sentinel-2 has been developed and is being operated by the European Space Agency. The satellites were manufactured by a consortium led by Airbus Defence and Space in Friedrichshafen, Germany. Overview The Sentinel-2 mission includes: * Multispectral image, Multi-spectral data with 13 bands in the Visible spectrum, visible, Infrared#Regions within the infrared, near infrared, and Infrared#Regions within the infrared, short wave infrared part of the Electromagnetic ...

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 Egrets hold a separate group with bitterns and herons within the 74 species found in the bird family Ardeidae. Many egrets are members of the genus, genera ''Egretta'' or ''Ardea (genus), 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 be ...

Caspian Roach
The Caspian roach (''Rutilus caspicus'') is a species of brackish water ray-finned fish belonging to the family Leuciscidae, which includes the daces, Eurasian minnows and related fishes. This fish is found in the Caspian Sea, commonly known as vobla. 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. Vobla is popular as a dried-fish snack. 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., ...

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 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''. It breeds in Southern Europe and in Western and Central Asia. Taxonomy The little bustard was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. He placed it with the other bustards in the genus '' Otis'' and coined the binomial name ''Otis tetrax''. Linnaeus designated the type locality as Europe but this has been restricted to France. The little bustard is now placed in its own genus ''Tetrax'' that was introduced in 1817 by Thomas Forster. The species is considered to be monotypic: no subspecies are recognised. The genus name and the specific epithet ''tetrax'' is the Latin word for an unidentified gamebird. Description Although the smallest Palearctic bustard, the little bustard is still pheasant-sized at long with a wingspan and a weight of . In flight, the long wings are extensively white. ...

Demoiselle Crane
The demoiselle crane (''Grus virgo'') is a species of crane found in central Eurosiberia, ranging from the Black Sea to Mongolia and Northeast 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''. Taxonomy The demoiselle crane was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. He placed it with the herons and cranes in the genus '' Ardea'' and coined the binomial name ''Ardea virgo''. He specified the type locality as the orient but this has been restricted to India. Linnaeus cited the accounts by earlier authors. The English naturalist Eleazar Albin had described and illustrated the "Numidian crane" in 1738. ...

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 .

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 documented in the New World in 1817 (New Jersey). John James Audubon, 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 bird migration, migratory; most European birds winter in Africa, and in North Ame ...
