We present an in vivo longitudinal MRI study that traces relative volume changes in the brain of juvenile male zebra finches from 20 to 200 days post hatching. In parallel, we also characterized song behavior to explore whether improvements in song performance can be linked to regional volume changes in the developing bird brain.
