Waarschijnlijk is dat eendje zijn moeder kwijt, ze lopen dan achter het eerste bewegende wezen aan dat ze zien.
Een paar jaar geleden hebben mijn ouders ook een klein eendje gehad die aldoor achter de hond aan bleef lopen.

Filial imprinting
The best-known form of imprinting is filial imprinting, in which a young animal acquires several of its behavioral characteristics from its parent. It is most obvious in nidifugous birds, which imprint on their parents and then follow them around. It was first reported in domestic chickens, by the 19th-century amateur biologist Douglas Spalding. It was rediscovered by the early ethologist Oskar Heinroth, and studied extensively and popularized by his disciple Konrad Lorenz working with greylag geese. Lorenz demonstrated how incubator-hatched geese would imprint on the first suitable moving stimulus they saw within what he called a "critical period" between 13–16 hours shortly after hatching. For example, the goslings would imprint on Lorenz himself (to be more specific, on his wading boots), and he is often depicted being followed by a gaggle of geese who had imprinted on him. Lorenz also found that the geese could imprint on inanimate objects. In one experiment, they followed a box placed on a model train in circles around the track.[1] Filial imprinting is not restricted to non-human animals that are able to follow their parents, however. In child development, the term is used to refer to the process by which a baby learns who its mother and father are. The process is recognised as beginning in the womb, when the unborn baby starts to recognize its parents' voices.
