  Upon coming outof their eggs, ducklings and chicks follow and become attached (socially bonded) to the first moving object they encounter (which usually, but not necessarily, is the mother duck or hen).The first scientific studies of this phenomenon were carried out by Austrian naturalist Konrad Lorenz (1903 - 1989), one of the founders of ethology (the study of animal behavior).

  He discovered thatif greylag geese were reared by him from hatching, they would treat him like a parental bird. The goslings followed Lorenz about and when they were adults they courted him in preference to other greylag geese. He first called the phenomenon "stamping in" in German, which has been translated to English as imprinting.

  In an anotherother experiment, he demonstrated that ducklings could be imprinted not only to human beings, but also to inanimate objects such as a white ball.
