There are many theories successful in explaining the observed correlations between black holes and their host galaxies. In turn, these theories play a crucial role in explaining many other observed aspects of the galaxy population. However, observational measurements of the interaction of black holes with their hosts remain scarce. I will present results on the growth of black holes in 400 local galactic bulges which have experienced a strong burst of star formation in the past 600 Myr. I will show how the processes at work in this local starburst sample may well be relevant to the co-evolution of black holes and bulges over cosmic time.
