阿彌陀經疏 1.167

1.167

經曰：「白鶴、孔雀、鸚䳇、舍利、迦陵頻伽、共命之鳥」，次第二別列禽名也。《佛華嚴不思議經》云：舍利者，此云鸜鵒鳥。迦陵頻伽，《智度論》云：迦陵頻伽者，此無正名，號好音鳥，此鳥子雖未出㲉，其音已勝眾鳥，何況出㲉！共命之鳥者，相傳云一身兩頭。

The sūtra says: "White cranes, peacocks, parrots, śārikas, kalaviṅkas, and jīvañjīvaka birds." Next, the second individually lists the names of the birds. The *Buddhāvataṃsaka-acintya-sūtra* states: as for 'śārika', here it is called the myna bird. Regarding the 'kalaviṅka', the *Mahāprajñāpāramitopadeśa* states: the kalaviṅka has no correct translation here; it is named the 'sweet-voiced bird'; even before this bird's chick has emerged from its eggshell, its voice already surpasses that of other birds, so how much more so once it has left the shell! As for the 'jīvañjīvaka bird', tradition says it has one body and two heads.
