Having a length of 41.9 to 44.5 cm and a weight of 340 to 440 g, Northwestern crows can be categorized as medium-sized birds.
- These black birds have a wingspan of around 99 cm. Their head, neck, back, wings, and tail are covered with iridescent black feathers with bluish-violet accents.
- Their shiny, robust bills are smaller and less strong than those of Common Ravens (Corvus corax), and they have brownish-grey eyes with smokey undertones.
- They also have feathers that resemble bristles protecting their nares. Large scales are exclusively present on the front side of Corvus caurinus’s broad, large black legs.
- While at rest, their folded wings’ tips do not reach the tips of their tails, which have slightly rounded ends.
- Although the male is somewhat bigger than the female, the sexes are similar in appearance[1].
Although less iridescent than adults, C. caurinus juveniles between the ages of 3 and 15 months are similarly black. Their tail, wings, and back feathers gradually turn brown from black. Young C. caurinus between the ages of one and three months have dull black feathers looser and fluffier than those of adults or immatures. Their eyes are blue.
