Abstract
AbstractSensitive periods for song acquisition by male swamp sparrows in the first year of life were compared, using two types of training protocol: 1) training with tape‐recorded songs and, 2) training by exposure to live singing tutors. Subjects were exposed to a range of tutors and tape recordings on regularly changing schedules. Singing was recorded, and the time of acquisition was determined by the occurrence of imitations of particular models. The results obtained with tape‐ and live‐tutoring were very similar. In both cases most learning occurred prior to 45–55 days of age. Some song acquisition occurred as late as 250–300 days of age.
