Abstract
⺠We measured the influence of song stimulation on maternal investment in canaries. ⺠We broadcast three types of songs (average, sexy and supranormal) to female canaries. ⺠Females exposed to supranormal stimuli laid bigger eggs than other females. ⺠We found no effect of the type of song on testosterone concentration in the eggs. ⺠It raises the question of how and why these different investment mechanisms evolved.
