In modern scientific classification, the Regulus regulus is the name of the English goldcrest, a tiny sparrow which is the smallest European bird, about 3-4 inches in length and weighing as little as 5 grams. Despite his tiny size, his golden crown may have earned him the name of “little king.” Compare the story of the fox and the turtle, #639.
