Abstract/Description: Among adult male zebra finches there is a striking two-fold variation in the morphology of several telencephalic regions that control song. The functional significance of such dramatic individual differences is presently unclear ¨C previous attempts to correlate enhanced morphology with song complexity have produced mixed results (e.g., MacDougall-Shackleton et al., 1998, Airey & DeVoogd, 2000). I have tested an alternative hypothesis, namely, that morphological differences in song regions are related to use. I tested this relationship in adult male zebra finches by selectively reducing vocal production while holding all environmental variables constant, save the timing of daily feeding. Access to food was restricted to the final 5-6h of a 14h light phase, a manipulation that attenuates daily undirected song production by two-thirds, but does not affect daily food intake or body mass (Johnson & Rashotte, 2002). Birds were initially maintained on ad lib conditions for 2mos and recorded weekly for 24h to establish baseline levels of daily undirected song production. They were then shifted to the restricted feeding protocol and held at
