Arginine vasotocin (AVT) has been implicated in the activation of courtship and aggressive behaviors in many vertebrate taxa. Here, we tested its effect on singing and other vocal behavior in a songbird. Female white-crowned sparrows (Z. l. gambelii) were implanted with chronic cannulae aimed at the third ventricle. Infusions of AVT dramatically increased the number of songs and other vocalizations during a 40 min period following infusion. Half of the subjects sang full song following AVT treatment. No bird sang after treatment with saline; any type of vocalization after saline treatment was rare. Female white-crowned sparrows are known to sing in both spring and winter in the wild; this behavior is thought to be aggressive, functioning in dominance interactions and territoriality. Central infusion of AVT induced singing and other vocalizations in estrogen-primed, photostimulated subjects as well as in non-reproductive subjects housed on short photoperiods. Thus, the effects of AVT on vocal behavior may not require breeding levels of gonadal steroids and are probably not seasonal. We hypothesize that both in the breeding and non-breeding seasons, AVT increases motivation to sing.
