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.

Northern Raven
Corvus corax
A mature common raven ranges between 54 and 71 cm (21 and 28 in) and has a wingspan of 116 to 153 cm (46 to 60 in). Recorded weights range from 0.69 to 2.250 kg (1.52 to 4.96 lb), thus making the common raven one of the heaviest passerines. Birds from colder regions such as the Himalayas and Greenland are generally larger with slightly larger bills, while those from warmer regions are smaller with proportionally smaller bills. Representative of the size variation in the species, ravens from California weighed an average of 0.784 kg (1.73 lb), those from Alaska weighed an average of 1.
