44. Listening for chat song packages.
6. Song Learning Often Creates Complex Songs and Large Repertoires
How a repertoire is delivered
From page 101 in the book.
Listening for chat song packages. Do the chat's "song packages" have a stable composition? For the bird in ♫433, for example, are the BOB and WHITE notes always in the same package, together with the other three sounds? It might take hours of listening to a single chat to find out, as you would have to wait for him to return to the BOB and WHITE notes after he delivered all manner of other sounds. All it would take is some time and fine listening to learn how the singing chat stores and organizes the songs in his brain. As of now, it's uncharted territory.
