Chap. 44 The Melancoryphus, the Erithacus, and the Phœnicurus
The change is different that takes place in the ficedula,3006 for this bird changes its shape as well as its colour. “Ficedula” is the name by which it is called in autumn, but not after that period; for then it is called “melancoryphus.”3007 In the same manner, too, the erithacus3008 of the winter is the “phœnicurus” of the summer. The hoopoe also, according to the poet Æschylus, changes its form; it is a bird that feeds upon filth3009 of all kinds, and is remarkable for its twisted top-knot, which it can contract or elevate at pleasure along the top of the head.
