Bird brains - song, speech, and genes

Bird brains (Nova Science)
We can learn to talk - how? Studying bird brains can help us find out. This video covers the following.

• How complex is bird song?
  Recordings slowed down sound more musical than you think, and have inspired at least one famous composer.
• What parts of the brain do birds use when singing and listening to song?
  The same parts as we use to speak and listen to speech, as revealed by functional MRI.
• Do birds stutter?
  Yes, some do! And the difference in brain function (from normal singing birds) is similar to the differences human stutterers show.
• Finding a mutant FOXP2 gene (the language gene) involved in an inherited speech disorder by studying an affected family, and then finding FOXP2 in birds and how it relates to song learning.
• The search for other genes that might explan why we can speak, and birds can sing, but other species (e.g. chimps) can't.
