Birds clean themselves and do not smell, their poo/pee is very easy to remove, they can stand on your shoulder and talk with you, they are adorable and they have the freedom which almost every bird has, and as good as no other animal possesses, they can fly. I don't know but there's something about being able to fly, being able to go where no other non-flying animal can go that fascinates me. I sometimes wish I were a bird.
