Abstract
This study addressed the question of how early learning processes in females influence later preferences for a male trait. I tested whether exposure to song alone (of a male other than the father) was sufficient for inducing a stable (repeatable) preference in female zebra finches (Taeniopygia guttata) by limiting early exposure to tape tutoring. A group of controls heard no songs before also being tested in adulthood. Repeated tests for preferences for tutor or unfamiliar song were made, interspersed with additional tests involving new songs. Preferences were tested in an operant task where pecking of response keys led to song playback. Most females significantly preferred one of the two songs in a given test. In the first test, the relative preference for the tutor song was significantly higher for the tutored than for the control females. Subsequently, tutored females' preferences for the tutor song remained higher on average, but the two groups did not differ significantly. However, tutored, but not untutored females' preferences were highly repeatable between tests, suggesting that early exposure to song might lead to a consolidation ol choice behaviour, a previously unknown effect of early exposure to song in female songbirds.
