Grasshopper Buzzard
The grasshopper buzzard (''Butastur rufipennis'') is a species of bird of prey in the family Accipitridae which is found in a narrow zone of sub-Saharan Africa north of the equator. Taxonomy The grasshopper buzzard forms a superspecies with the white-eyed buzzard (''Butastur teesa''), rufous-winged buzzard (''Butastur liventer''), and grey-faced buzzard (''Butastur indicus'') all of which occur in Asia. Description The adult grasshopper buzzard is grey brown above with a darker head and dark shaft streaks on all of its feathers. The feathers of the mantle and lesser coverts are narrowly with fringed rufous in fresh plumage, although this wears off. The grey tail has faint brown bars. The greater coverts and primary feathers are light rufous, the primaries are tipped with black, and form a conspicuous reddish patch in flight. The secondary feathers are rufous shading to dark brown towards the tip, which is white. The chin and throat are whitish, with three black streaks on e ...

Carl Jakob Sundevall
Carl Jakob Sundevall (22 October 1801, Högestad – 2 February 1875) was a Swedish zoologist. Sundevall studied at Lund University, where he became a Ph.D. in 1823. After traveling to East Asia, he studied medicine, graduating as Doctor of Medicine in 1830. He was employed at the Swedish Museum of Natural History, Stockholm from 1833, and was professor and keeper of the vertebrate section from 1839 to 1871. He wrote ''Svenska Foglarna'' (1856–87) which described 238 species of birds observed in Sweden. He classified a number of birds collected in southern Africa by Johan August Wahlberg. In 1835, he developed a phylogeny for the birds based on the muscles of the hip and leg that contributed to later work by Thomas Huxley. He then went on to examine the arrangement of the deep plantar tendons in the bird's foot. This latter information is still used by avian taxonomists. Sundevall was also an entomologist and arachnologist, for which (for the latter field) in 1833 he publi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gambia
The Gambia,, ff, Gammbi, ar, غامبيا officially the Republic of The Gambia, is a country in West Africa. It is the smallest country within mainland AfricaHoare, Ben. (2002) ''The Kingfisher A-Z Encyclopedia'', Kingfisher Publications. p. 11. . and is surrounded by Senegal, except for its western coast on the Atlantic Ocean. The Gambia is situated on both sides of the lower reaches of the Gambia River, the nation's namesake, which flows through the centre of the Gambia and empties into the Atlantic Ocean, thus the long shape of the country. It has an area of with a population of 1,857,181 as of the April 2013 census. Banjul is the Gambian capital and the country's largest metropolitan area, while the largest cities are Serekunda and Brikama. The Portuguese in 1455 entered the Gambian region, the first Europeans to do so, but never established important trade there. In 1765, the Gambia was made a part of the British Empire by establishment of the Gambia. In 196 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Prey Of Sub-Saharan Africa
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 ...

Butastur
''Butastur'' is a genus of birds of prey in the family Accipitridae. Taxonomy and species The genus ''Butastur'' was introduced in 1843 by the English naturalist Brian Houghton Hodgson with the white-eyed buzzard as the type species. The genus name is a portmanteau of the genus ''Buteo ''Buteo'' is a genus of medium to fairly large, wide-ranging raptors with a robust body and broad wings. In the Old World, members of this genus are called "buzzards", but " hawk" is used in the New World (Etymology: ''Buteo'' is the Latin na ...'' introduced by Bernard Germain de Lacépède for the buzzards and ''Astur'' introduced by Lacépède for the goshawks.

Sun Spider
Solifugae is an order of animals in the class Arachnida known variously as camel spiders, wind scorpions, sun spiders, or solifuges. The order includes more than 1,000 described species in about 147 genera. Despite the common names, they are neither true scorpions (order Scorpiones), nor true spiders (order Araneae). Most species of Solifugae live in dry climates and feed opportunistically on ground-dwelling arthropods and other small animals. The largest species grow to a length of , including legs. A number of urban legends exaggerate the size and speed of the Solifugae, and their potential danger to humans, which is negligible. Anatomy Solifuges are moderately small to large arachnids (a few millimeters to several centimeters in body length), with the larger species reaching in length, including legs. In practice, the respective lengths of the legs of various species differ drastically, so the resulting figures are often misleading. More practical measurements refer primar ...

Scorpion
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs, and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their taxonomy is being revised to account for 21st-century genomic studies. Scorpions primarily prey on insects and other invertebrates, but some species hunt vertebrates. They use their pincers to restrain and kill prey, or to prevent their own predation. The venomous sting is used for offense and defense. During courtship, the male and female grasp each other's pincers and dance while he tries to move her onto ...

Grasshopper
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among what is possibly the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which allow them to escape from threats by leaping vigorously. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a nymph or "hopper" which undergoes five moults, becoming more similar to the adult insect at each developmental stage. The grasshopper hears through the tympanal organ which can be found in the first segment of the abdomen attached to the thorax; while its sense of vision is in the compound eyes, the change in light intensity is perceived in the simple eyes (ocelli). At high population densities and under certain environmental conditions, some grasshopper species can change color and behavior and form swarms. Unde ...

Many important hominid fossils have been found in Tanzania, such as 6-million-year-old Pliocene hominid fossils. The genus Australopithecus ranged across Africa between 4 and 2 million years ago, and the oldest remains of the genus '' Homo'' are found near Lake Olduvai.

Cameroon
Cameroon (; french: Cameroun, ff, Kamerun), officially the Republic of Cameroon (french: République du Cameroun, links=no), is a country in west-central Africa. It is bordered by Nigeria to the west and north; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon and the Republic of the Congo to the south.
