I personally find it irritating when people lumb ravens in with crows. Yes they are cousins but that doesn't mean that they are the same. Ravens for one are ALOT bigger than crows as adults, and are much more intelligent than their smaller cousin. Although you can mistake a young raven for an adult crow there are distinct attributes that set them apart, raven's have a more solid body and a more predatory look to their beaks. Plus unlike the greasy look that crows have to their feathers, ravens have a purple hue to their black feathers.
