Details

Rook is found more often in areas with arable land, river and steppe regions, where the soil is soft and fertile.

Features

  • Sedentary species, which lives in large colonies, extremely noisy.
  • Intense black plumage with purplish reflexes, jagged feathers.
  • Adult birds have a whitish gray area of skin at the base of the beak to the eye and the feathers on the head, neck and shoulders are dense and silky.
  • Strong, sharp beak, with white base and black top.
  • Length: 45 cm.
  • Wingspan: between 75 and 90 cm.
  • Omnivorous diet (varied diet).

Behavior

The rooks install their nest in trees, often several nests in the same tree. This can lead both to darkening trees and the noise pollution around. Moreover, like any harmful bird, because of the large number of individuals of a colony, the accumulation of droppings can damage structures. The deterioration is caused by uric acid (organic acid resulting from the combustion of poultry protein). Rooks are carriers of the  West Nile terrible virus (crows brought this virus in the US in 1999). In regions where agriculture is practiced, rooks avoid areas where winter wheat is grown and prefer areas where spring wheat can ne found, so it is regarded as a pest species.
