Imprinting is an innate behavior in which an animal, typically a bird or mammal, forms a strong attachment to the first moving object it encounters during a critical period early in life, which is usually shortly after hatching or birth. Imprinting is accompanied by simple learning, as the animal learns to recognize and follow its imprinted object or parent.
