Ravens have the ability to recognize old friends and react negatively to seeing a foe, said a study in the journal Current Biology. Marcus Bockle, a University of Vienna zoologist, and his team describe a group of 12 ravens kept together for three years, then separated. Three years later, they recorded them and played their calls to one another. "If they heard a friend, then they called out in a friendly voice," he said, opposed to an unfriendly (deeper and elongated) voice.

Ravens (and crows) are interesting critters. Back in the day when Owatonnabill was a lad growing up in the wilds of the Superior National Forest, a kid up the road had a raven that could talk. Didn't say much ("good fella", "hi there", stuff like that) but it was understandable. Crows are fun too. A few years back we had one hanging around work, that would eat cigarette butts out of ashtrays. He'd get a little pie-eyed and sort of wobble around the feet of the smokers, but after the buzz wore off he'd be right back for more.
