Summary:
Elevated yolk progesterone has been shown to impair prenatal, but facilitate postnatal auditory learning in bobwhite quail chicks. Elevated yolk testosterone has facilitated prenatal learning, but its effects on postnatal auditory learning in quail are unknown. Either testosterone or an oil vehicle was injected into bobwhite quail eggs prior to incubation. Control eggs were unmanipulated. Following hatching, chicks were exposed to a conspecific maternal call (A or B) for 240 min. At 48 hr, chicks were tested for their preference for the familiarized vs. novel call. All groups demonstrated a preference for the familiar call (p < .05), but minimal between group difference were found. Contrary to previous research, elevated yolk testosterone neither facilitated nor impaired postnatal auditory learning in bobwhite quail chicks. Further research will examine underlying mechanisms responsible for differential effects and explore if similar systems are involved in other species-typical processes such as social motivation.
