When these little birds come visiting in groups, they always seem to be in a hurry. There's no time for etiquette. Nosh. That's what it is all about. No "Hello" or "Hi". Just "Where's my grain?" if you care. You see, they have places to be. They are free to go wherever their wings behoove. They can fly away whether you feed them or not. It's you who is inside a cage.
