This bird really learned how to get through without worrying too much about normal bird's work. One mets them hanging around in tourist areas with fast food restaurants or - even better fun - in Jemma's tree house in Speyside. They are not afraid to take the food from human hands, but it's too much effort for them. It's much easier to wait 'til the tourists leave the table and then to decide themselves what to take and what to leave for the dustbin. Their name is Carib Grackle - sounds ridiculous, but I don't think they really bother.
