Song Learning

노래 학습

Definition

The process by which young birds learn their species-specific vocalizations, often from adult tutors during a sensitive period.

Detailed Explanation

Song learning occurs in two phases: a sensory phase where the young bird memorizes a tutor's song, and a sensorimotor phase where it practices until its song matches the memorized template. Different species have different degrees of openness to learning — some are closed-ended learners with a brief critical period; others like canaries learn new songs each year. Song dialects — geographic variation in learned songs — can act as assortative mating cues, contributing to population divergence.
