Songbirds learn to sing from a hymn sheet in their head, according to a new study.
Swiss researchers have identified a region of the Zebra Finch brain which they believe has an internal recording of how the birds ought to be singing.
A separate region seems to enable the birds to identify mistakes in their songs, they wrote in Nature journal.
The research could also shed light on how humans learn to speak, according to scientists from Zurich University.
They monitored the electrical activity of cells in the zebra finches brains which are associated with listening.
They did this as the birds were singing, and while the birds were listening to recordings of other zebra finches.
