Ontario Highway 71

Ontario Highway 71.
King's Highway 71 is a provincially maintained highway in the Canadian province of Ontario. Part of the Trans-Canada Highway, the 194-kilometre (121 mi) route travels west from the Fort Frances-International Falls International Bridge in Fort Frances, concurrently with Highway 11, for 40 kilometres (25 mi). At Chapple, Highway 71 branches from Highway 11, travelling 154 kilometres (96 mi) north to a junction with Highway 17 just east of Kenora. The concurrent portion of the highway follows the Cloverleaf Trail, which was completed by the end of the 1880s and improved over the next several decades. The portion between Highway 11 and Highway 17 follows the Heenan Highway, which connects the Rainy River region with Kenora and the remainder of Ontario's road network; before its opening the area was accessible only via the United States. Both highways were incorporated into the provincial highway system in 1937 following the merger of the Department of Highways and the Department of Northern Development.

Meteorological history of Hurricane Ivan

Meteorological history of Hurricane Ivan.
The meteorological history of Hurricane Ivan (2004) spans 26 days from late August to late September, the tenth longest storm duration of any Atlantic hurricane on record. The tropical cyclone developed from a tropical wave that moved off the coast of Africa on August 31. Tracking westward due to a ridge, it developed into Tropical Depression Nine on September 2, gradually intensifying until September 5, when it underwent rapid deepening and reached Category 4 status on the Saffir-Simpson Hurricane Scale. At the time Ivan was the southernmost major North Atlantic hurricane on record. It was weakened by dry air but gradually reorganized, passing just south of Grenada as a major hurricane on September 7. The hurricane attained Category 5 status in the central Caribbean Sea, and passed just south of Jamaica, the Cayman Islands, and western Cuba with winds at or slightly below that. Ivan gradually weakened before making landfall just west of Gulf Shores, Alabama, on September 16 with winds of 120 mph (195 km/h). After weakening, crossing Florida, restrengthening, and making another landfall in Louisiana, its circulation dissipated in Texas on September 25.

Pallas's leaf warbler

Pallas's leaf warbler.
Pallas's leaf warbler (Phylloscopus proregulus) is a migratory bird that breeds in mountain forests from southern Siberia east to northern Mongolia and northeastern China. It is named for German zoologist Peter Simon Pallas, who first described it. It winters mainly in and near southern China, although in recent decades increasing numbers have been found in Europe in autumn. One of the smallest Eurasian leaf warblers, it has a relatively large head and short tail. It has greenish upperparts and white underparts, a lemon-yellow rump, and yellow double wingbars and supercilia. The female builds a cup nest in a tree or bush, and incubates four to six eggs that hatch after 12 or 13 days. The chicks are fed mainly by the female and fledge when they are 12–14 days old. Pallas's leaf warbler feeds on small insects and spiders. It forages in bushes and trees, picking items from leaves or catching prey in short flights or while hovering. The species has a large range, its numbers are believed to be stable, and it is not endangered.

Nikolai Rimsky-Korsakov

Nikolai Rimsky-Korsakov.
Nikolai Rimsky-Korsakov (1844–1908) was a Russian composer, a member of a group of prominent composers known as The Five, who worked together in Saint Petersburg in the mid-19th century. Considered a master of orchestration, his best-known compositions, which include Capriccio Espagnol, the Russian Easter Festival Overture, and the symphonic suite Scheherazade, are considered staples of the classical music repertoire, along with suites and excerpts from some of his 15 operas. Scheherazade is an example of Rimsky-Korsakov's frequent use of fairy tale and folk subjects; he also left a considerable body of original Russian nationalist compositions. His preparation of works by The Five for performance brought them into the active classical repertoire, although his editing of the music of Modest Mussorgsky created controversy. As a shaper of a generation of younger composers and musicians during his decades as an educator, he is considered the main architect of what the classical music public considers the Russian style of composition.
