**Abstract:** Bengalese finches (BF) had been domesticated from wild White-Rumped Munias (WRM) for more than 260 years. During these years, WRMs were selected for parental behavior and white plumages. But not only those, their courtship songs distinctively changed although there is no record for artificial selection. While WRMs sing song syllables in a strict sequence, BFs sing syllables in more variable sequences. We believe song sequential complexity evolved based on two factors. One is behavioral plasticity developed under domestication that increased social tolerance. The other is indirect sexual selection by females, meaning that reproductive effort is paid more by a female when paired with a complex song singer. These two factors prepared the basis of culturally evolving complex songs in BFs. To support this, evidence for domestication syndrome in Bengalese finches will be presented.
