Discrimination of song types and variants in song sparrows
Article Abstract:
A study has been conducted to examine the mechanism underlying the discrimination of song types and variants by male song sparrows, Melospiza melodia, using a habituation/recovery paradigm. Cluster analysis of playbacks revealed habituation during playback of focal songs. Recovery was low for between-song type switches, significant for within-type switches on the last and first three minutes, and highly significant for between-type switches than for within-type switches on both the last three-minute pre-switch, first three-minute post-switch and the first and last six-min. pre-switch. These suggest that there is greater perception of song types than variants.

Ontogeny of vocal tract movements during song production in song sparrows
Article Abstract:
Correspondance between vocal tract movements and syringeal activity is essential for pure-tone song production in song sparrows. A study conducted on laboratory-grown song sparrows, Melospiza melodia, shows varying rates of acoustics and beak movements during song development. Gradual and independent development of motor systems is observed during ontogeny, a period during which coordination of syringeal activity with vocal tract movements is delayed.

The evolution of bird song: male and female response to song innovation in swamp sparrows
Article Abstract:
The songs of swamp sparrows are compared for their ability to attract mates, depending upon the relative innovation of the song syntax. Female birds are shown to be more conservative about song syntax than male birds.
