Crow (corvo)

15 Jul

Scientific name: Corvus corax

St James’s Park (London).

Corvo – St James’s Park (Londres).

The true crows are large passerine birds that form the genus Corvus 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 offshore and oceanic islands (including Hawaii).

In the United States and Canada, the word “crow” is used to refer to the American Crow. The crow is a year round species. The crow genus makes up a third of the species in the Corvidae family. Other corvids include rooks and jays. Crows appear to have evolved in Asia from the corvid stock, which had evolved in Australia. A group of crows is called a “murder”.

O corvo é uma ave da família Corvidae, representantes de maiores dimensões da Ordem passeriformes. Possuem ampla distribuição geográfica nas zonas temperadas de todos os continentes, vivendo em bandos com estrutura hierárquica bem definida e formam, geralmente, casais monogâmicos. Sua alimentação é omnívora e inclui pequenos invertebrados, sementes e frutos; podem ser também necrófagos. Tais aves surgiram na Ásia, mas todos os continentes temperados e várias ilhas (como o Havaí) tem representantes de 40 ou mais membros do genêro. Na mitologia, os corvos são vistos geralmente como portadores de maus presságios, devido à sua plumagem negra e hábitos necrófagos.
