sexual imprinting

the development of a preference for a sexual partner that occurs during a sensitive or critical period. For example, if zebra finches are cross-fostered to Bengalese finch parents for the first 40 days of life, they will prefer to mate with Bengalese finches as adults. In addition, birds often prefer to socialize with other birds that resemble those they were exposed to in the first month of life.
