These data show that as a bird ages, there are changes in the volume of brain regions involved in producing birdsong, specifically: higher vocal center (HVC), robustus archistriatum (RA), and lateral magnocellular nucleus of the anterior neostriatum (LMA
N). How does each region change, and what does this suggest about their function in birdsong?
