How do you tell the difference between a big crow and a raven?

Question

I have to sit in a car outside for 12 hours where I work, and I've started to watch nature to pass the time.

I honestly want to know, how do you tell the difference between a big crow and a raven?

Are ravens actually that much bigger, that it's obvious?

I know this is under Pets>Birds, but Y!A doesn't have an ornithology section.

Answer 1

Crows average around 17 inches long, and ravens about 24-27.

    * A raven weighs about four times that of a crow.

    * Crows have a wing span around 2.5 ft., and ravens about 3.5-4 ft.

          o A raven's wing sometimes makes a prominent "swish, swish" sound, while a crow's wingbeat is usually silient.

    * Ravens have pointed wings, while crows have a more blunt and splayed wing tip.

    * Crows have a fan-shaped tail (squared-off), while raven tails are long and wedge-shaped.

    * Besides having a bigger, more powerful bill, a raven's bill is curved, while a crow has a more-or-less flat bill. Additionally, atop a raven's bill is a tuft of hairs absent on crows.

          o As a result of being larger and more powerful, ravens are the more efficient predator. (Predation is a very small percentage of crow and raven diets.)

a Raven's throaty croak sounds nothing like the "caw" of a crow

here is a good image of both....
