Abstract: Birdsong, in non‐tropical species, is generally more common in spring and summer when males sing to attract mates and/or defend territories. Changes in the volumes of song control nuclei, such as HVC and the robust nucleus of the arcopallium (RA), are observed seasonally. Long photoperiods in spring stimulate the recrudescence of the testes and the release of testosterone. Androgen receptors, and at times estrogen receptors, are present in HVC and RA as are co‐factors that facilitate… Expand
The Role of Neurotrophins in the Seasonal-Like Growth of the Avian Song Control System
TLDR
The results indicate that BDNF is sufficient to promote the seasonal plasticity in somatic area and cell density in RA, although NT-3 may also contribute to this process, and suggest that HVC may be a presynaptic source of increased levels of BDNF in RA of breeding-condition birds. Expand
Seasonal and hormonal modulation of neurotransmitter systems in the song control circuit
TLDR
Selective pharmacological manipulations confirmed that the noradrenergic system indeed plays a role in the control of singing behavior, and more experimental work is needed to identify specific genes related to neurotransmission that are regulated by steroids in functionally defined brain areas to enhance different aspects of song behavior.

Testosterone Mediates Seasonal Growth of the Song Control Nuclei in a Tropical Bird
TLDR
Together, data indicate that T mediates seasonal changes in the HVC and RA of both tropical and higher- latitude bird species even if the environmental signals differ. Expand
Early seasonal development of brain song control nuclei in male blue tits
TLDR
An extremely early seasonal growth of the song control nuclei HVC and RA in Corsican blue tits is reported indicating that the vernal development of these nuclei occurs well before the Vernal increase in plasma testosterone, testes size and song activity. Expand
Testosterone and social context affect singing behavior but not song control region volumes in adult male songbirds in the fall
TLDR
The data suggest that photoperiodic condition and social context may modulate the effects of steroids on SCRs and singing behavior. Expand
Seasonal-like growth and regression of the avian song control system: neural and behavioral plasticity in adult male Gambel's white-crowned sparrows.
TLDR
This mini-review discusses the steroidal and cellular mechanisms underlying seasonal-like growth and regression of the song control system in adult male Gambel's white-crowned sparrows, and its impact on song behavior. Expand
Influence of Testosterone Metabolites on Song-Control System Neuroplasticity during Photostimulation in Adult European Starlings (Sturnus vulgaris)
TLDR
It is suggested that the contributions of DHT and E2 signaling in songbird neuroplasticity may be regulated by photoperiod and that future studies should account for species and sex differences in the brain. Expand
2.12 – Neural and Hormonal Control of Birdsong
TLDR
This chapter reviews studies examining the neural control of song and functions of endocrine systems that influence the song control system to reveal how sex steroids can act to build motor and learning pathways and then stimulate plasticity of these circuits to modify song throughout adult life. Expand
Testosterone regulates birdsong in an anatomically specific manner
TLDR
By selectively implanting testosterone into specific brain regions of castrated male canaries, Serinus canaria, the medial preoptic area is identified as a critical site for the induction of a generalized increase in motivation that includes the motivation to sing, illustrating how a single hormone can coordinate changes in many aspects of a complex behaviour to facilitate successful reproduction.

Cell death and the song control system: A model for how sex steroid hormones regulate naturally‐occurring neurodegeneration

TLDR
The results demonstrate that the study of cell death in the song control system provides an excellent opportunity for understanding how changes in circulating levels of sex steroids affect the degeneration of hormone‐sensitive brain circuits. Expand

Neuroendocrinology of Song Behavior and Avian Brain Plasticity: Multiple Sites of Action of Sex Steroid Hormones
TLDR
Testosterone effects on neuroplasticity in the song system may be indirect in that behavioral activity stimulated by testosterone acting in sites that promote male sexual behavior could in turn promote morphological changes in thesong system. Expand
Roles of photoperiod and testosterone in seasonal plasticity of the avian song control system.
TLDR
Although testosterone is the primary factor mediating seasonal changes in neural attributes of the song nuclei, photoperiod may act via mechanisms that are independent of steroid levels to supplement or modulate the actions of testosterone. Expand
Melatonin Binding in the House Sparrow Song Control System: Sexual Dimorphism and the Effect of Photoperiod
TLDR
The data point to a role for the circadian system of house sparrows in song control, but a specific role for melatonin in the daily or seasonal regulation of the song control system in birds, could not be determined. Expand
Photoperiodic condition modulates the effects of testosterone on song control nuclei volumes in male European starlings.
TLDR
Results suggest that photorefractoriness renders the song nuclei of starlings less sensitive to stimulatory effects of T, and plasticity in the starling song system appears to require the coordination of the appropriate hormonal milieu with a permissive photoperiodic condition. Expand
Seasonal changes in the densities of α2‐noradrenergic receptors are inversely related to changes in testosterone and the volumes of song control nuclei in male European starlings
TLDR
The results suggest that changes in T, volumes of song nuclei, and α2‐receptor densities might regulate seasonal changes in song behavior or the context that will elicit song in male starlings. Expand
Effects of Testosterone and Photoperiodic Condition on Song Production and Vocal Control Region Volumes in Adult Male Dark-Eyed Juncos (Junco hyemalis)
TLDR
It is indicated that the stimulating influence of LD exposure on HVc volumes is insufficient to induce song in the absence of elevated plasma T levels, and photoperiodic manipulations should be considered for large volume induction in photorefractory males. Expand
Photoperiodic regulation of the male house sparrow song control system: gonadal dependent and independent mechanisms.
TLDR
The data support the view that the song control system of the house sparrow is regulated by the photoperiodic timing system independently of gonadal influence, but that the gonads augment seasonal regulation of song, presumably via steroidal hormone secretion. Expand
Identification, distribution, and developmental changes of a melatonin binding site in the song control system of the zebra finch
TLDR
Melatonin binding sites in HVC could link HVC‐based song control to circadian and circannual changes in the photoperiod independent of gonadal steroids, suggesting that melatonin has a role in the motor control of singing. Expand
Seasonal neuroplasticity in the songbird telencephalon: a role for melatonin.
TLDR
Exogenous melatonin attenuated the long-day-induced volumetric increase in high vocal center and also decreased the volume of another song-control nucleus, area X, which is the first direct evidence of a role for melatonin in functional plasticity within the central nervous system of vertebrates.

TLDR
There was a striking downregulation of MelR in the song control nucleus Area X of intact and castrated photostimulated birds on long days compared to their photorefractory counterparts on the same long days and to the short‐day groups. Expand
