We don't have ravens in North Florida, so I don't need to distinguish between crows and ravens at home, but when traveling I can usually tell them apart by size and beak shape. I didn't know that ravens have longer throat feathers and that will be helpful for close up IDs in the future. Sometimes it's challenging to distinguish crows from grackles when they're flying. We also have Fish Crows, which I can distinguish from American Crows by their call.
