Maybe. A challenge in birding is getting close enough to look at things without scaring them away. The thing about both crows and ravens is they are (relatively) unafraid of humans. So, you shouldn't struggle much to get a good enough look to differentiate.

That's assuming Ravens are present in your area. One of the first things the guide books teach is to differentiate based on range. E.g. a candidate crow/Raven in Iowa is most likely a crow, since Ravens' range doesn't include the great plains.

Let me finish by plugging birding as a relaxing pastime that doesn't require much investment (just a $25 guide book for your area), and can really enhance any time spent out doors.
