From πελαργός.  On the pious affection of the stork, cf. Plato, Alc. i. 135 (§ 61), Arist., H.A. ix. 13, 20, Ælian, H.A. iii. 23 and x. 16, and Plin. x. 32.  From πελαργὸς was supposed to be derived the Pythagorean word πελαργᾶν (Diog. Laert. viii. 20), but this is now regarded as a corruption of πεδαρτᾶν.
