Detailed explanation-1: -Ducklings and chickens follow the first moving object they see after hatching. They become emotionally attached to this object. This type of behaviour is called imprinting. Young ones recognise their mother because of imprinting.

Detailed explanation-2: -During a young duckling’s imprinting, images of the duckling’s mother (and its siblings) act like a metaphorical stamp, leaving an impression in the brain that guides the young duckling on who to follow. Outside of the sensitive period, this bond will fail to form.

Detailed explanation-3: -Filial imprinting: It is the most common type of imprinting seen between a parent and the newborn. For example, ducks and geese. Sexual imprinting: It is a type of imprinting where the animal learns the mate preferences at a young age by observing the parents as role models.

Detailed explanation-4: -For example, after birth or hatching, the newborn follows another animal that it recognizes or marks as its mother (filial imprinting). Another example is when a young goose after hatching can follow its future mating partner and when mature it will start to mate with its imprinted partner (sexual imprinting).

Detailed explanation-5: -imprinting, in psychobiology, a form of learning in which a very young animal fixes its attention on the first object with which it has visual, auditory, or tactile experience and thereafter follows that object.
