Abstract
Male white-crowned sparrows have song "dialects," acquired in about the first 100 days of life by learning from older males. In the laboratory an alien white-crowned sparrow dialect can be taught. Once the song is established further acoustical experience does not change the pattern. White-crowned sparrows do not copy recorded songs of other sparrow species presented under similar conditions.Keywords: BEHAVIOR, ANIMAL; BIRDS; EXPERIMENTAL LAB STUDY; LEARNING; VOICE
