Common Raven

These Ravens were walking on the ice of a small lake.
Not just large but massive, with a thick neck, shaggy throat feathers, and a Bowie knife of a beak. In flight, ravens have long, wedge-shaped tails. They're more slender than crows, with longer, narrower wings, and longer, thinner “fingers” at the wingtips.
Common Ravens are entirely black, right down to the legs, eyes, and beak.
