Ravens vary their vocalizations from a low, gurgling croak to harsh grating sounds while a crow will make a series of loud, rhythmic caws or a mixture of caws, coos and clicks.

Unfortunately, young American crows, especially when begging for food from their parents, often sound like fish crows.

Many years ago when Danny, that city boy, was putting in the garden in the field, he heard a loud crrroooak and thought a person was imitating a raven, but not very well. He had never seen or heard ...

When the peep hole was open and the recorded sound another raven played over a loudspeaker, the birds took extra care to ensure their food was placed out of sight.

They have a similar appearance to crows, but if you see the two birds together the difference is fairly obvious. Curt Stager and Martha Foley discuss ravens and crows on Natural Selections.

The crow’s bill is petite in comparison. In flight, the raven’s tail is long and wedged-shaped or longer in the middle than on the sides verses a more rounded shorter tail in the crow.
