Apus Unicolor
The plain swift (''Apus unicolor'') is a medium-sized Swift (bird), swift. Although this bird is superficially similar to a barn swallow or Common house martin, house martin, it is not related to those passerine species. The resemblances between the groups are due to convergent evolution reflecting similar life styles. Swifts have very short legs that they use only for clinging to vertical surfaces. They never settle voluntarily on the ground, and spend most of their lives in the air, feeding on insects that they catch in their beaks. They drink on the wing. Plain swifts breed in colonies on cliffs, bridges and buildings on the Canary Islands and Madeira, laying two eggs in a saucer-shaped nest made of flowerheads glued with saliva. They are partially bird migration, migratory, with many birds leaving to winter in mainland Africa. Until recently it was thought that the birds wintered on the African coast but recent studies suggest they travel much further to the equatorial forest ...

William Jardine (naturalist)
Sir William Jardine, 7th Baronet of Applegarth FRS FRSE FLS FSA (23 February 1800 – 21 November 1874) was a Scottish naturalist. He is known for his editing of a long series of natural history books, ''The Naturalist's Library''. Life and work Jardine was born on 23 February 1800 at 28 North Hanover Street in Edinburgh, the son of Sir Alexander Jardine, 6th baronet of Applegarth and his wife, Jane Maule. He was educated in both York and Edinburgh then studied medicine at Edinburgh University. From 1817 to 1821 he lodged with Rev Dr Andrew Grant at James Square, an arrangement made by his father. Grant was minister of St Andrew's Church on George Street. In his early years, aged only 25, he was elected a fellow of the Royal Society of Edinburgh his proposer being Sir David Brewster. He was a co-founder of the Berwickshire Naturalists' Club, and contributed to the founding of the Ray Society. He was "keenly addicted to field-sports, and a master equally of the rod ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of The Canary Islands
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

Apus (genus)
The bird genus ''Apus'' comprise some of the Old World members of the family Apodidae, commonly known as swifts. They are among the fastest birds in the world. They resemble swallows, to which they are not related, but have shorter tails and sickle-shaped wings. Swifts spend most of their life aloft, have very short legs and use them mostly to cling to surfaces. Taxonomy The genus ''Apus'' was erected by the Italian naturalist Giovanni Antonio Scopoli in 1777 based on tautonymy and the common swift which had been given the binomial name ''Hirundo apus'' by the Swedish naturalist Carl Linnaeus in 1758. The name ''Apus'' is Latin for a swift, thought by the ancients to be a type of swallow with no feet (from Ancient Greek α, ''a'', "without", and πούς, ''pous'', "foot"). Before the 1950s, there was some controversy over which group of organism should have the genus name ''Apus''. In 1801, Bosc gave the small crustacean organisms, known today as ''Triops,'' the genus nam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boomerang
A boomerang () is a thrown tool, typically constructed with aerofoil sections and designed to spin about an axis perpendicular to the direction of its flight. A returning boomerang is designed to return to the thrower, while a non-returning boomerang is designed as a weapon to be thrown straight and is traditionally used by some Aboriginal Australians for hunting. Historically, boomerangs have been used for hunting, sport, and entertainment and are made in various shapes and sizes to suit different purposes. Although considered an Australian icon, ancient boomerangs have also been discovered in Africa, the Americas, and Eurasia. Description A boomerang is a throwing stick with aerodynamic properties, traditionally made of wood, but also of bone, horn, tusks and even iron. Modern boomerangs used for sport may be made from plywood or plastics such as ABS, polypropylene, phenolic paper, or carbon fibre-reinforced plastics. Boomerangs come in many shapes and sizes dependin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pallid Swift
The pallid swift (''Apus pallidus'') is a small bird, superficially similar to a barn swallow or house martin. It is, however, completely unrelated to those passerine species, since the swifts are in the order Apodiformes. The resemblances between the groups are due to convergent evolution reflecting similar life styles. Swifts have very short legs which they use only for clinging to vertical surfaces. The genus name ''Apus'' is Latin for a swift, thought by the ancients to be a type of swallow with no feet (from Ancient Greek α, ''a'', "without", and πούς, ''pous'', "foot"), and ''pallidus'' is Latin for "pale". They never settle voluntarily on the ground. Swifts spend most of their lives in the air, living on the insects they catch in their beaks. They drink on the wing. Taxonomy The pallid swift was first described by English naturalist George Ernest Shelley in 1870. Description This long species is very similar to the common swift, and separation is only possible with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Swift
The common swift (''Apus apus'') is a medium-sized bird, superficially similar to the barn swallow or house martin but somewhat larger, though not stemming from those passerine species, being in the order Apodiformes. The resemblances between the groups are due to convergent evolution, reflecting similar contextual development. The swifts' nearest relatives are the New World hummingbirds and the Southeast Asian treeswifts. Its scientific name ''Apus'' is Latin for a swift, thought by the ancients to be a type of swallow with no feet (from Ancient Greek α, ''a'', "without", and πούς, ''pous'', "foot"). Swifts have very short legs which they use primarily for clinging to vertical surfaces (hence the German name ''Mauersegler'', literally meaning "wall-glider"). They never settle voluntarily on the ground, where they would be vulnerable to accidents and predation, and non-breeding individuals may spend up to ten months in continuous flight. Taxonomy The common swift was one o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swift (bird)
The swifts are a family, Apodidae, of highly aerial birds. They are superficially similar to swallows, but are not closely related to any passerine species. Swifts are placed in the order Apodiformes with hummingbirds. The treeswifts are closely related to the true swifts, but form a separate family, the Hemiprocnidae. Resemblances between swifts and swallows are due to convergent evolution, reflecting similar life styles based on catching insects in flight. The family name, Apodidae, is derived from the Greek ἄπους (''ápous''), meaning "footless", a reference to the small, weak legs of these most aerial of birds.Jobling (2010) pp. 50–51.Kaufman (2001) p. 329. The tradition of depicting swifts without feet continued into the Middle Ages, as seen in the heraldic martlet. Taxonomy Taxonomists have long classified swifts and treeswifts as relatives of the hummingbirds, a judgment corroborated by the discovery of the Jungornithidae (apparently swift-like hummingbird-relati ...

Canary Islands
The Canary Islands (; es, Canarias, ), also known informally as the Canaries, are a Spanish autonomous community and archipelago in the Atlantic Ocean, in Macaronesia. At their closest point to the African mainland, they are west of Morocco. They are the southernmost of the autonomous communities of Spain. The islands have a population of 2.2 million people and they are the most populous special territory of the European Union. The seven main islands are (from largest to smallest in area) Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, and El Hierro. The archipelago includes many smaller islands and islets, including La Graciosa, Alegranza, Isla de Lobos, Montaña Clara, Roque del Oeste, and Roque del Este. It also includes a number of rocks, including those of Salmor, Fasnia, Bonanza, Garachico, and Anaga. In ancient times, the island chain was often referred to as "the Fortunate Isles".
