Context determines the sex appeal of male zebra finch song.
We explored the conditions under which playbacks of male zebra finch, Taeniopygia guttata, song induced reproduction in females. In a laboratory study, a rise in faecal oestrogen levels predicted egg laying. Song playbacks by themselves induced a decrease in oestrogen levels. There was an increase in oestrogen levels, followed by egg laying, when the song was broadcast from inside a male model ...
متن کاملBegging calls support offspring individual identity and recognition by zebra finch parents.
In colonial birds, the recognition between parents and their offspring is essential to ensure the exclusivity of parental care. Although individual vocal recognition seems to be a key component of parent-chicks recognition, few studies assessed the period when the emergence of the vocal signature takes place. The present study investigated the acoustic cues of signaler identity carried in the b...
متن کاملDevelopmental song learning in the zebra finch
Developmental learning (for example, speech acquisition in human infants) takes place early in life but its effects may last the entire lifetime of the individual. Developmental learning is difficult to study because the behavioral changes involved span many time scales: The challenge is to relate the developmental parameters to behavioral changes, which can occur within hours as well as across...
متن کاملOntogeny and individual variation in the adrenocortical response of zebra finch (Taeniopygia guttata) nestlings.
Numerous studies indicate interspecies variation in the ontogeny of the adrenocortical response in birds; however, little is known about the extent of interindividual variation in avian young. Toward this end, we examined the ontogeny and interindividual variation in the adrenocortical response in zebra finch (Taeniopygia guttata) nestlings. We measured baseline and stress-induced total (bound ...
متن کاملSex-specific effects of prenatal testosterone on nestling plasma antioxidant capacity in the zebra finch.
Trans-generational transfer of non-genetic, maternal resources such as hormones can have a substantial influence on offspring phenotype in many vertebrate species. In birds, maternal androgens enhance both growth and competitive behaviour, but also suppress the immune system. It has been hypothesised that high levels of egg androgens could also influence the prooxidant-antioxidant balance throu...
