On 5 June 1995 an adult male mallard (Anas platyrhynchos) collided with the glass façade of the Natuurmuseum Rotterdam and died. Another drake mallard raped the corpse almost continuously for 75 minutes.
Then the author, Kees Moeliker, disturbed the scene and secured the dead duck. Dissection showed that the rape-victim indeed was of the male sex. It is concluded that the mallards were engaged in an ‘Attempted Rape Flight’ that resulted in the first described case of homosexual necrophilia in the mallard.
