I knew somebody who had logged in Alaska and they swore that this one town had a huge crow who would hang out by the town's welcome sign and...welcome the visitors. Apparently crows who spend enough time around people will sometimes mimic human speech and this particular crow had been taught to welcome people in.

If you like that crow you'll probably get a kick out of Ngarritj the corella: https://www.youtube.com/watch?v=ZbSxc6Y1aVA

18 minute short film about a very social corella that adopted an entire community in the north of Australia, surfing on car bonnets, stealing cards from players, performing for food, hurling insults, teasing dogs, etc.
