(Theoklymenos:) "Telemachos, not without a god's will did this bird fly past you on the right, for I knew when I saw it that it was a portent. No other family shall be kinglier than yours in the country of Ithaka, but you shall have lordly power forever." (15.531-534)
Because obviously the gods have nothing better to do than send birds flying around to serve as omens.
