American Crow
Corvus brachyrhynchos
The American crow is a large, distinctive bird with iridescent black feathers all over. Its legs, feet, and bill are also black. They measure 40–53 cm (16–21 in) in length, of which the tail makes up about 40%. The wing chord is 24.5 to 33 cm (9.6 to 13.0 in), with the wingspan ranging from 85 to 100 cm (33 to 39 in). The bill length can be from 3 to 5.5 cm (1.2 to 2.2 in), varying strongly according to location. The tarsus is 5.5 to 6.5 cm (2.2 to 2.6 in) and the tail is 13.5 to 19 cm (5.3 to 7.5 in). The body mass can vary from 316 to 620 g (11.1 to 21.9 oz).

Carrion Crow
Corvus corone
The plumage of the carrion crow is black with a green or purple sheen, much greener than the gloss of the rook (Corvus frugilegus). The bill, legs, and feet are also black. It can be distinguished from the common raven by its size, around 48–52 cm (19–20 in) in length, as compared to an average of 63 cm (25 in) for ravens, and from the hooded crow by its black plumage. The carrion crow has a wingspan of 84–100 cm (33–39 in) and weighs 400–600 g (14–21 oz).
