    In birds, maternal hens deposit steroid hormones in the egg during egg formation. Elevated levels of yolk progesterone in bobwhite quail eggs has been shown to impair prenatal auditory learning, but facilitate postnatal auditory learning in quail chicks. In contrast, elevated yolk testosterone has been shown to facilitate prenatal auditory learning, but its effects on postnatal auditory learning are unknown. This study is assessing whether elevated prenatal levels of testosterone, within the naturally occurring range, impair or facilitate postnatal auditory learning in quail chicks.
