I dont know about Pica Pica, but they are black and white ,they kinda look like they are wearing a dinner suit, they have a reputation for thievery, but in reality it is just a strange fascination for things that shine or sparkle, hence the stories about them stealing jewellery from opened windows. I think there may be an opera called the "thieving Magpie" but im not sure
