 Golden Eagle Range of golden Eagle Scientific classification Kingdom: Animalia Phylum: Chordata Class: Aves Order: Accipitriformes Family: Accipitridae Genus: Aquila Species: A. chrysaetos golden eagle, (Aquila chrysaetos), dark brown eagle of the family Accipitridae, characterized by golden lanceolate nape feathers (hackles), dark eyes, yellow cere, gray beak, fully feathered legs, large yellow feet, and great talons. Its wingspread reaches 2.3 metres (almost 8 feet). It is the national bird of Mexico. In North America the golden eagle ranges from central Mexico along the Pacific coast and through the Rocky Mountains as far north as Alaska and Newfoundland. Small numbers range through the Appalachian Mountains as far south as North Carolina. The golden eagle is protected by federal law throughout the United States, but special permits for the shooting of eagles are issued in areas where the birds are believed to kill lambs. Ornithologists estimate that the world’s population of golde

 Valentine's Day Also called Saint Valentine's Day or the Feast of Saint Valentine Observed by People in many countries; Anglican Communion  Lutheran Church  Traditionalist Catholicism  Type Christian, romantic, cultural, commercial observance Significance Feast day of Saint Valentine; the celebration of love and affection Observances Sending greeting cards and gifts, dating, church services, novenas Date February 14 (fixed by the Western Christian Church) July 6 (fixed by the Eastern Orthodox Church) July 30 (fixed by the Eastern Orthodox Church) Frequency Annual Valentine’s Day, also called St. Valentine’s Day, holiday (February 14) when lovers express their affection with greetings and gifts.

 Ice Age An ice age is a period in which the earth's climate is colder than normal, with ice sheets capping the poles and glaciers dominating higher altitudes. Within an ice age, there are varying pulses of colder and warmer climatic conditions, known as 'glacials' and 'interglacials'. Even within the interglacials, ice continues to cover at least one of the poles. In contrast, outside an ice age temperatures are higher and more stable, and there is far less ice all around. The earth has thus far made it through at least five significant ice ages. One glance at our icy poles and frozen peaks makes it clear that our current epoch (the Holocene, c. 12,000-present day) actually represents an interglacial within the ice age that spans the Quaternary geological period, which started around 2,6 million years ago and encompasses both the Pleistocene (c. 2,6 million years ago - c. 12,000 years ago) and the Holocene epochs. This entire period is characterised by cycles of up

His vigorous patronage of Buddhism during his reign (c. 265–238 BCE; also given as c. 273–232 BCE) furthered the expansion of that religion throughout India. Following his successful but bloody conquest of the Kalinga country on the east coast, Ashoka renounced armed conquest and adopted a policy that he called “

Almost all the rest are part of a mainly nonmigrating Florida population. These majestic white birds are the tallest in North America. They live in family groups and frequent marshes, shallow lakes, and lagoons. Cranes feed by foraging

 Varangian Guard The mercenary Varangian Guard was an elite Byzantine army corps and the personal bodyguard of emperors beginning with Basil II in c. 988 CE. The Viking unit was famous for the stature of its members and their blood-thirsty conduct in battle, where they used their fearsome double-bladed battle-axes to devastating effect. Celebrated recruits include Harald Hardrada, who went on to become the king of Norway, and the Icelandic hero Bolli Bollason. Later, after the 1066 CE Battle of Hastings in England, especially, they became a largely Anglo-Saxon unit. By the beginning of the 14th century CE they had outlasted their usefulness but, for a few centuries at least, the Varangians were probably as shocking a sight to Byzantine enemies as tanks would have been to WWI infantry. Basil II Basil II reigned as emperor from 976 to 1025 CE, and despite a hugely successful military career which saw the Byzantine empire almost double its territories, he got off to the worst possible sta

 Hamster A Winter white dwarf hamster Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Rodentia Family: Cricetidae Subfamily: Cricetinae hamster, (subfamily Cricetinae), any of 18 Eurasian species of rodents possessing internal cheek pouches. The golden hamster (Mesocricetus auratus) of Syria is commonly kept as a pet. Hamsters are stout-bodied, with a tail much shorter than their body length, and have small furry ears, short stocky legs, and wide feet. Their thick long fur ranges from grayish to reddish brown, depending upon the species; underparts range from white to shades of gray and black. The Dzhungarian hamster (Phodopus sungorus) and the striped dwarf hamster (Cricetulus barabensis) have a dark stripe down the middle of the back. Dwarf desert hamsters (genus Phodopus) are the smallest, with a body 5 to 10 cm (about 2 to 4 inches) long. The largest is the common hamster (Cricetus cricetus), measuring up to 34 cm long, not including a short tail
