Research conducted at Rutgers University has shown that Zebra finches rewire the “language” parts of their brains in response to being placed with different birds with different types of song.  Scientists have known that birds learn their song similarly to how humans learn language – through hearing, imitation, and feedback.  Their brains show similar plasticity with nerves involved in language learning.  Specific nerves bundle together when learning specific songs, as birds learn to attend to specific notes.  These nerves separate when the birds are placed in isolation.  For more details, read the rest of the story here:  Tuning Into a New Language on the Fly (Science Daily)
