I was watching CSI yesterday and they referred to a person suffering from pica - a disorder in which the person eats non-traditional things like dirt, plastic, coins, raw ingredients, and other strange things. If you saw the series premiere of Grey's Anatomy, you would have seen a patient on that show who was eating large amounts of coins. So how does this tie into birds? Pica is the genus name for the Magpie family (Black-billed and Yellow-billed in the US). The disorder is named after the magpie because it is thought that the magpie has a very non-discerning diet.
