It is generally recognized that singing in canaries is limited to the male and as such this may be considered as a secondary sexual characteristic. In order to determine if this behavior is conditioned by secretions of the testis, male hormone was injected into female birds. The canaries used were raised by a local breeder, Mr. J. Frederichs, who has developed a hardy strain of birds by acclimating them to life out of doors throughout the year. They were brought into the laboratory in January… Expand
Inheritance and Learning in the Song of the Chaffinch (Fringilla Coelebs L.)
Observations of male Chaffinches reared in isolation from the age of a week show that the song has an innate basis but that the perfect song has to be learnt by imitation in spring, when the young birds begin to sing. Expand
Testosterone-dependency of male solo song in a duetting songbird — Evidence from females
The results suggest that solo singing in white-browed sparrow weavers is under the control of gonadal steroid hormones, which is not male-specific but can be activated in females under certain conditions. Expand
Gonads and Singing Play Separate, Additive Roles in New Neuron Recruitment in Adult Canary Brain
It is suggested that singing and gonadal factors promote, separately, the recruitment of new neurons and that when they exert this effect together they do so in an additive manner. Expand
Regulatory mechanisms of testosterone-stimulated song in the sensorimotor nucleus HVC of female songbirds
Testosterone-induced singing of female robins correlated with cellular differentiation processes in the HVC that were partially similar to those seen in theHVC of testosterone-treated female canaries, and brain-derived neurotrophic factor likely functions as a common mediator of the testosterone effects in HVC.

Testosterone Induces Sexual Release Quality in the Song of Female Canaries
Data demonstrate that testosterone treatment not only induces a male-like structure in the songs of females, but also induces functionally ‘male-like’ songs. Expand
Sexual differentiation of brain and behavior in birds
It is proposed that copulatory behavior in zebra finches is differentiated in a manner similar to what has been described in quail, but that novel approaches need to be considered to understand the differentiation of the telencephalic song control system. Expand

The role of sexual selection and female choice in shaping the link between testosterone and courtship will be addressed and how courtship traits that are activated by testosterone can be apparently independent of hormone blood concentrations are discussed. Expand
The endocrine basis of breeding behaviour in the feral pigeon (Columba livia). I. Effects of exogenous hormones on the pre-incubation behaviour of intact males.
FSH and prolactin on the pre-incubation behaviour of intact male Columba livia were investigated and the implication of the various hormone treatments is discussed in relation to the normal behavioural-endocrine cycle of the pigeon. Expand
17 β‐Estradiolbenzoate‐dependent Song Induction in Juvenile Female Canaries (Serinus canaria): — Long‐term Measurements of Song Activity —
Tests of the behavioral sensitivity to TP as adults in relation to different pretreatment showed that the females which received estrogens as juveniles provided higher song activities in response to the androgen and showed shorter behavioral latencies towards TP. Expand
Some Effects of Prolactin on Reproductive Behavior in the Brown-Headed Cowbird (Molothrus ater)
Comparison of the reaction of prolactininjected cowbirds exposed to nests, eggs, and young with the reactions of uninjected control birds under similar conditions explored some of the physiological basis of parasitic nesting habits and their possible evolutionary development. Expand
