Carrion crow

The plumage of carrion crow is black with a green or purple sheen, much greener than the gloss of the rook. The bill, legs and feet are also black. It can be distinguished from the common raven by its size (48–52 cm or 19 to 20 inches in length as compared to an average of 63 centimetres (25 inches) for ravens) and from the hooded crow by its black plumage. The carrion crow has a wingspan of 84–100 cm or 33 to 39 inches and weighs 400–600 grams.
