Temporal relationships in white-throated sparrow song

Article Abstract:

The presence of temporal relationships in the song of the white-throated sparrow was determined. The durations of the notes were correlated, likewise the duration of the inter-noteintervals. However, the duration of the notes did not correlate with the inter-note interval durations. Hence, although the notes and intervals may havedistinct tempos, the entire song may not have an overall rhythm. The inter-noterelationships were less defined than those previously reported for the species.

The response of male and female Song Sparrow to geographic variation in song

Article Abstract:

Male and female Song Sparrow response to local and foreign songs was tested by measuring the copulatory response of females and aggressive response of males to playback of local and foreign songs. Results showed that both male and female responded more strongly to local songs than to foreign songs recorded at a distant site. Acoustic differences exist between songs from the two populations, which suggests their ability to discriminate between local and foreign songs.
