The importance of birds and bird song in Afghan culture is embedded in Afghanistan’s two official languages—Dari and Pashto—in which the nightingale, a central poetic symbol, occurs in texts sung by urban and rural singers.
The songs of particular birds are associated with calls to prayer, and mullahs confirm that birdsong is regarded within Sufism as a form of religious singing; birds are welcomed at Sufi shrines, where feeding them is considered an act of piety.
Sometimes caged birds are brought to musical performances in Herāt, and when they are stirred to sing by hearing music their sounds are heard as an integral and treasured part of the performance.
This according to “Afghan perceptions of birdsong” by John Baily (The world of music XXXIX/2 [1997] pp. 51–59).
