Stimulation of sexual development in female Japanese quail by male song: influence of ecoethological variables

Abstract : As the stimulatory effect of male song on sexual development of young female quail is well known, we have investigated the influence of different ecoethological variables on this function. Natural social structures in quail (Coturnix coturnix japonica and Coturnix coturnix coturnix) were taken into account to test ecoethological parameters of production of this social signal: theme loudness diversity and frequency. Two successive experiments showed that song intensity seems not to be an important feature, and that the stimulatory effect of songs is greater when they possess a wide range of thematic variations and a high broadcasting rate. These features are characteristics of small natural groups of reproductive singing males, especially during the dawn and the dusk song peaks. Their stimulatory effect can be observed at the physiological level (female gonadal development) and in behavioural changes (non-agressive nature of contact-call during encounters). Female responses to male song, however, indicated important individual differences. Several hypotheses are discussed to explain these data.
