“…For example, a large amount of direct and indirect evidence has been collected in many avian species which indicates that the response to salient social cues such as a displaying conspecific requires stimulus cues derived primarily from visual and auditory stimulation (Lehrman 1959;Hinde & Steel 1978;Silver 1978;Cheng 1979;Wingfield 1980;Moore 1983;Crews & Silver 1985;Erickson 1985;Ball & Balthazart 2002). There is little evidence that other sensory systems such as the somatosensory and olfactory systems play a major role in mediating the effects of social stimuli on endocrine secretion as they clearly do in mammals (Wingfield 2006).…”

Although it is axiomatic that males and females differ in relation to many aspects of reproduction related to physiology, morphology and behaviour, relatively little is known about possible sex differences in the response to cues from the environment that control the timing of seasonal breeding. This review concerns the environmental regulation of seasonal reproduction in birds and how this process might differ between males and females. From an evolutionary perspective, the sexes can be expected to differ in the cues they use to time reproduction. Female reproductive fitness typically varies more as a function of fecundity selection, while male reproductive fitness varies more as a function sexual selection. Consequently, variation in the precision of the timing of egg laying is likely to have more serious fitness consequences for females than for males, while variation in the timing of recrudescence of the male testes and accompanying territory establishment and courtship are likely to have more serious fitness consequences for males. From the proximate perspective, sex differences in the control of reproduction could be regulated via the response to photoperiod or in the relative importance and action of supplementary factors (such as temperature, food supply, nesting sites and behavioural interactions) that adjust the timing of reproduction so that it is in step with local conditions. For example, there is clear evidence in several temperate zone avian species that females require both supplementary factors and long photoperiods in order for follicles to develop, while males can attain full gonadal size based on photoperiodic stimulation alone. The neuroendocrine basis of these sex differences is not well understood, though there are many candidate mechanisms in the brain as well as throughout the entire hypothalamo-pituitary-gonadal axis that might be important.

“…In the sow, vocalizations may compensate for the absence of olfactory signals and allow immobilization behavior of the female [26]. Also, in birds, male courtship vocalizations have a stimulatory effect on ovarian activity [27,28]. In the red deer (Cervus elaphus), the play-back of recorded vocalizations from males during courtship advanced the onset of the breeding season compared with that of isolated females [29].…”

-Under temperate and subtropical latitudes, ewes and goats display a reproductive seasonal pattern and their sexual activity during the anestrous period can be stimulated and synchronized by the introduction of males in the group, which is called the "male effect". The response of females to the male effect in the middle of the anestrous season is weak or absent. This failure may be due to the inability of the female to respond to males, as a result of a refractoriness of the female to the male stimulus. But, it may also be due to a low quality stimulus provided by the male which is, as the females, in seasonal rest. We tested this latter hypothesis in seasonally inactive goats kept under subtropical conditions by comparing the use of males with their sexual behavior stimulated or not by photoperiodic treatments. Treated males were able to induce estrous activity of females during the whole anestrus season. We have also determined that previous separation of the males and continuous contact during teasing are not absolute requisites when active bucks are used. While odor from the male and its sexual behavior play a primary role in inducing ovulation, vocalizations appear to facilitate the display of the does' estrous. It remains to be determined to which extent these conclusions apply under temperate latitudes and with more seasonal breeds.goat / male effect / buck vocalizations / male odor / sexual behavior / photoperiodic treatment

“…Although photoperiod may be the best predictor of the most favourable time of year to breed, it does not inform the animal about the availability of mates in a particular locality, and thus the suitability of becoming reproductively active in a specific place at any given time. On the other hand, there is evidence that social cues emanating from conspecifics can influence the timing of reproductive function in birds (Schwab & Lott, 1969;Cheng, 1976;Hinde & Steel, 1978) and oestrous cyclicity and the occurrence of ovulation in a number of mam¬ malian species (rodents: Whitten, 1956;Vandenbergh, 1969Vandenbergh, , 1977McClintock, 1978; ungulates: Grubb & Jewell, 1973;Martin et al, 1980;Chemineau, 1983), as well as the synchrony of menstrual cycles in human and non-human primates (McClintock, 1971;Rowell & Dixson, 1975;Russell et al, 1980). The (Legan el al, 1977).…”
