Physical Differences. Crows and ravens differ physically from one another, their size being the most noticeable. Ravens are larger than crows, making them the largest perching birds. Crows have a smooth texture whereas the raven has a dense and shaggy plumage particularly around the throat. The bill of the raven is also heavier than the crow's bill. During flight, the spreading of the tail can distinguish the crow and raven apart. The tail of the crow spreads into a fan-like structure while the tail of the raven spreads into a wedge shape.
Crows are adaptive, intelligent, and abundant; they are found pretty much everywhere in all kinds of habitats. They are also very social creatures. We use the phrase âas the crow fliesâ to describe a direct path, a reference to the crowâs ability to go anywhere and do anything. Most crows eat carrion; they do not kill. Rather, they dine on the remains of animals, or the leftovers of other predators. Crows waste nothing. They serve an important function in the cycle of life, cleaning up and contributing to the easier decomposition of a corpse.
