![]() All features, except for the ESD ( p = 0.1040), were significantly different from 0 at p < 0.05 (see Results). Points are the average for each male, black lines indicate the mean across males. ![]() ![]() Positive values indicate an increase and negative values indicate a decrease in the feature from non-courtship to courtship singing. ( b) Social modulation of a number of song features. The ESD and STE were measured for all syllables. Arrows highlight two renditions of two different syllables (black versus grey) where the FF would be the lowest frequency band. We also measured the mean and CV of the FF across renditions of syllables with flat harmonic structure. For all songs, we counted the number of introductory syllables (black bars) and number of motifs per bout (grey bars). ( a) Spectrogram of non-courtship song from a male zebra finch. These data highlight the critical role of developmental auditory experience in shaping the perception and processing of song performance.ĮGR1 auditory processing preference social context zebra finch.ĭevelopmental song exposure shapes behavioural responses to song. Additionally, auditory responses to courtship and non-courtship song were altered in adult females raised without developmental song exposure. However, unlike females allowed to hear and interact with an adult male during development, females reared without developmental song exposure did not demonstrate behavioural preferences for high-performance courtship songs. Zebra finch males modulate their song performance when courting females, and previous work has shown that females prefer the high-performance, female-directed courtship song. Consequently, we investigated how developmental exposure to adult male song affected behavioural and neural responses to song in a small, gregarious songbird, the zebra finch. Moreover, female songbirds are often sensitive to variation in male song performance. In songbirds, females use song to identify males and select mates. Furthermore, the neural substrates that development could act upon to influence the processing of performance features remains largely unknown. However, relatively little is known about the degree to which the perception of and preference for differences in motor performance are shaped by developmental experiences. The performance of courtship signals provides information about the behavioural state and quality of the signaller, and females can use such information for social decision-making (e.g.
