 In the Talmud, the raven is described as having been only one of three beings on Noah's Ark that copulated during the flood and so was punished.The Rabbis believed that the male raven was forced to ejaculate his seed into the female raven's mouth as a means of reproduction.Pirke De-Rabbi Eliezer (chapter 25) explains that the reason the raven Noah released from the ark did not return to him was that the raven was feeding on the corpses of those who drowned in the flood.
