Davian behavior is a scientific term of art referring to copulation with a dead conspecific. It was first observed in ground squirrels and was named after an old limerick ("There was an old miner named Dave/ who kept a dead whore in his cave/You have to admit/He hadn't much wit/But look at the money he saved!"). Davian behavior has since been observed and published in birds and anurans. This behavior also occurs in humans, and the fact that there are laws against it, assumes that it must be controlled. Such laws are typically titled "abuse of a corpse."
