Pelican in piety

In medieval Europe, the pelican was thought to be particularly attentive to her young, to the point of providing her own blood when no other food was available. As a result, the pelican became a symbol of the Passion of Jesus and of the Eucharist. It also became a symbol in bestiaries for self-sacrifice, and was used in heraldry ("a pelican in her piety" or "a pelican vulning (wounding) herself"). Another version of this is that the pelican used to kill its young and then resurrect them with its blood, this being analogous to the sacrifice of Jesus. These legends may have arisen because the pelican used to suffer from a disease that left a red mark on its chest. Alternatively it may be that pelicans look as if they are stabbing themselves as they often press their bill into their chest to fully empty their pouch. Yet other possibilities are that they often rest their bills on their breasts, and that the Dalmatian Pelican has a blood-red pouch in the early breeding season.
