Résumé :	Bachman's Sparrow (Aimophila aestivalis) at Fort Pickett Maneuver Training Center, Virginia, was regularly observed mimicking the primary song of an Indigo Bunting (Passerina cyanea). Two Bachman's Sparrows were observed mimicking the primary song of a Common Yellowthroat (Geothlypis trichas). Although there is a previous report of a Bachman's Sparrow mimicking the song of a Field Sparrow (Spizella pusilla), there are no prior reports of Bachman's Sparrows mimicking Indigo Bunting or Common Yellowthroat songs.
