White-eyed river martin

White-eyed river martin . The white-eyed river martin (Pseudochelidon sirintarae) is a passerine bird in the swallow family. First found in 1968, it is known only from a single wintering site in Thailand, and may be extinct, since there have been no confirmed sightings since 1980 despite targeted surveys in Thailand and Cambodia. The adult has mainly glossy greenish-black plumage, a white rump, and a tail with two long central feathers that widen to a racket-shaped tip. It has a white eye ring and a broad, bright greenish-yellow bill. The juvenile lacks the tail ornaments and is browner. Like other swallows, it feeds on insects caught in flight, and its wide bill suggests that it may take relatively large species. It roosts in reed beds in winter, and may nest in river sandbanks. Its apparent demise may have been hastened by trapping, loss of habitat and dam construction. The martin is one of only two birds endemic to Thailand. The country's government has featured the bird on a s

Apollo 15

Apollo 15 . Apollo 15 (July 26 – August 7, 1971) was the fourth crewed mission to land on the Moon. It was the first J mission, with a longer stay on the Moon (July 30 – August 2) and a greater focus on science, including the first Lunar Roving Vehicle. David Scott and James Irwin landed near Hadley Rille and spent 18+1⁄2 hours on extravehicular activity, collecting 170 pounds (77 kg) of surface material. At the same time, Alfred Worden orbited the Moon, operating the sensors in the SIM bay of the service module. During the return trip, Worden performed the first spacewalk in deep space. The Apollo 15 mission splashed down safely, with all goals accomplished, but was marred when it emerged that the crew had carried unauthorized postal covers to the lunar surface, some of which were sold by a West German stamp dealer. The crew was reprimanded for poor judgment, and did not fly in space again. The mission also saw the collection of the Genesis Rock, thought to be part of the Moon's

Andreas Palaiologos

Andreas Palaiologos . Andreas Palaiologos (1453–1502) was the elder son of Thomas Palaiologos, Despot of the Morea, and a nephew of Constantine XI Palaiologos, the final Byzantine emperor. After the fall of Constantinople in 1453 and the Ottoman invasion of the Morea in 1460, Andreas's father fled to Corfu with his family. Upon his father's death in 1465, Andreas moved to Rome and was recognized as the titular Despot of the Morea and as the chief claimant to the ancient imperial throne. Although his father had never claimed the title, Andreas proclaimed himself "Emperor of Constantinople" from 1483 onwards, a claim that was supported by some of the Byzantine refugees who lived in Italy. Andreas traveled around Europe in search of a ruler who could aid him in retaking Constantinople, but rallied little support. In 1481 an expedition he started organizing to restore the Byzantine Empire was canceled. He died in poverty in Rome in 1502 and was buried in St. Peter's

R. A. B. Mynors

R. A. B. Mynors . R. A. B. Mynors (28 July 1903 – 17 October 1989) was an English classicist and medievalist who held the senior chair of Latin at the universities of Oxford and Cambridge. He served as the Kennedy Professor of Latin at Cambridge from 1944 to 1953 and as the Corpus Christi Professor of Latin at Oxford from 1953 until his retirement in 1970. Mynors had the reputation of one of Britain's foremost classicists. A textual critic, he specialised in the study of manuscripts and their role in the reconstruction of classical texts. He was an expert on palaeography, and has been credited with unravelling a number of highly complex manuscript relationships. His publications include critical editions of Vergil, Catullus, and Pliny the Younger. In addition to receiving honorary degrees and fellowships from various institutions, Mynors was made a Knight Bachelor in 1963. He died in a car accident, aged 86. His comprehensive commentary on Vergil's Georgics was published posth

It features extensive technical enhancements while retaining the original core gameplay, and includes new single-player and multiplayer content.

Siege of Calais (1346–1347)

Siege of Calais (1346–1347) . The Battle of Caen on 26 July 1346 was an assault on the French-held town by a force of archers and men-at-arms, part of an invading English army under King Edward III during the Hundred Years' War. This force, nominally commanded by the Earls of Warwick and Northampton, was eager for plunder, and attacked against orders, before the rest of their army was in position. Caen was garrisoned by 1,000–1,500 soldiers and a large number of armed townsmen, commanded by Grand Constable of France Raoul, the Count of Eu. The town was captured in the first assault; over 5,000 of the ordinary soldiers and townspeople were killed and a small number of nobles were taken prisoner. After sacking the town for five days, the army marched to the River Seine, and by 12 August they were 20 miles (32 kilometres) from Paris. After turning north they heavily defeated the French at the Battle of Crécy two weeks later, and commenced the successful siege of Calais the following

Oryzomys dimidiatus

Oryzomys dimidiatus . Oryzomys dimidiatus, also known as the Nicaraguan oryzomys, Thomas's rice rat, or the Nicaraguan rice rat, is a rodent in the genus Oryzomys of the family Cricetidae. It is known from only three specimens, all collected in southeastern Nicaragua (range pictured) since 1904. Placed in Nectomys upon its discovery, it was later classified in its own subgenus of Oryzomys and finally recognized as closely related to other species now placed in Oryzomys, including the marsh rice rat and Oryzomys couesi, which occurs in the same region. With a head and body length of 118 to 128 mm (4.6 to 5.0 in), O. dimidiatus is a medium-sized rice rat. The upperparts are gray-brown and the underparts are grayish, not buffy as in O. couesi. The tail is only slightly darker above than below. All three specimens were caught near water and the species may be semiaquatic, spending some time in the water. There is currently not enough data to make a proper assessment of its conservatio
