Not quite crows, but a pair of ravens are featured in Daniel Suarez's book on drone swarms, "Kill Decision." Great read by a great author if you like technothrillers. Be aware; both crows and ravens will remember your face, as some researchers at college campuses have found years later, with crows that didn't so much always appreciate the experimentation. But as with most creatures, be nice, and they're nice to you. They've even got a limited ability to mimic, which can get fun.
