Harper Bird is a quest item which is needed during Find out What Happened to Montaron in Baldur's Gate II: Shadows of Amn and Baldur's Gate II: Enhanced Edition. The bird is added to the inventory of a character who interacts with the cage on the first floor of the Harper Building in Athkatla Docks. This needs to be brought to Xzar.


From what the Spectral Harpists have said, you gather that this bird was once poor Montaron. This would be what Xzar is looking for.
