Cape crow

The Cape crow or black crow (Corvus capensis) is slightly larger (48–50 cm in length) than the carrion crow and is completely black with a slight gloss of purple in its feathers. It has proportionately longer legs, wings and tail too and has a much longer, slimmer bill that seems to be adapted for probing into the ground for invertebrates. The head feathers have a coppery-purple gloss and the throat feathers are quite long and fluffed out in some calls and displays.

Distribution and habitat

This species occurs in two large separate regions of the African continent. One form ranges from the Cape at the southern tip of Africa up to southern Angola and across to the east coast of Mozambique. The other population occurs in a large area from South Sudan, Ethiopia,Tanzania and Kenya in central east Africa. The more northern population is on average slightly smaller than the southern. It inhabits open grassland, moorland, agricultural areas with some trees or woodland in the vicinity for nesting. It seems to thrive especially in agricultural areas.

Cape

A cape is a sleeveless outer garment, which drapes the wearer's back, arms and chest, and fastens at the neck.

History

Capes were common in medieval Europe, especially when combined with a hood in the chaperon, and have had periodic returns to fashion, for example, in nineteenth-century Europe. Roman Catholic clergy wear a type of cape known as a ferraiolo, which is worn for formal events outside of a liturgical context. The cope is a liturgical vestment in the form of a cape. Capes are often highly decorated with elaborate embroidery. Capes remain in regular use as rain wear in various military units and police forces, for example in France. A gas cape was a voluminous military garment designed to give rain protection to someone wearing the bulky gas masks used in twentieth century wars.

Semantic distinction

In fashion, the word “cape” usually refers to a shorter garment and “cloak” to a full-length version of the different types of garment, though the two terms are sometimes used synonymously for full-length coverings. The fashion cape does not cover the front to any appreciable degree. In raingear, a cape is usually a long and roomy protective garment worn to keep one dry in the rain.

Corvus (genus)

Corvus is a widely distributed genus of birds in the family Corvidae. Ranging in size from the relatively small pigeon-sized jackdaws (Eurasian and Daurian) to the common raven of the Holarctic region and thick-billed raven of the highlands of Ethiopia, the 40 or so members of this genus occur on all temperate continents except South America, and several islands. In Europe, the word "crow" is used to refer to the carrion crow or the hooded crow, while in North America, it is used for the American crow, fish crow, or the northwestern crow.

The crow genus makes up a third of the species in the family Corvidae. The members appear to have evolved in Asia from the corvid stock, which had evolved in Australia. The collective name for a group of crows is a 'flock' or a 'murder'.

Recent research has found some crow species capable of not only tool use, but also tool construction. Crows are now considered to be among the world's most intelligent animals with an encephalization quotient equal to that of many non-human primates.
