I love seeing our ravens -- we've had a pair (well, I think it's the same pair; a little hard to tell...) that hangs around our yard for the past several years. Lots of other ravens in the vicinity, but this one particular pair always seems to be around, cleaning up under the bird feeders. Really fun when the young ones start coming out -- even when they're as big as the parents they're still squawking and begging to be fed.
