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).

Fish Crow
Corvus ossifragus
The fish crow is a medium-large bird, with an average adult weight of 280–320 grams (9.9–11.3 oz) in males and 247–293 grams (8.7–10.3 oz) in females. The wingspan is approximately 36 inches (90 cm), while the total body length is between 36–40 centimetres (14–16 in). The fish crow is superficially similar to the American crow, but is smaller and has a silkier, smoother plumage by comparison, and the bill is usually somewhat slimmer. The upperparts have a blue or blue-green sheen, while the underparts have a more greenish tint to the black. The eyes are dark brown.
