“…For example, prolactin levels were elevated in male red-eyed vireos during incubation relative to other stages of breeding, despite males not participating in incubation duties (Van Roo, 2003). This pattern of elevated prolactin titers in fathers prior to the hatching of eggs, even when males do not participate in incubation, has been described in other biparental passerines as well (e.g., Campbell et al, 1981;Dawson and Goldsmith, 1982;Goldsmith, 1982;Hiatt et al, 1987;Schoech et al, 1996;Silverin and Goldsmith, 1983;Wingfield and Goldsmith, 1990).…”

“…In addition to photorefractoriness, the maintenance of moderately elevated prolactin levels after the first breeding event could inhibit re-nesting and relaying because of its anti-steroidogenic effects Dawson and Sharp, 1998, but see Wingfield et al (1989)). Supporting this hypothesis, prolactin levels decrease between breeding events in several multiple brood species (Goldsmith et al, 1981;Goldsmith, 1982;Silverin, 1991), whereas they remain elevated after the parental phase in some single brood species that may show relative refractoriness only (e.g. Garcia et al, 1996;Lormée et al, 1999).…”

“…Although all species exhibit elevated circulating prolactin levels during incubation, prolactin levels drop at the time of hatching in many precocial species ( Fig. 2A, Etches et al, 1979;Sharp et al, 1979;Lea et al, 1981;Goldsmith and Williams, 1980;Goldsmith, 1982;Hall and Goldsmith, 1983) whereas they remain elevated during the chickrearing period in altricial species ( Fig. 2A, Dawson and Goldsmith, 1982;Hector and Goldsmith, 1985;Hall, 1986;Seiler et al, 1992;Lormée et al, 1999Lormée et al, , 2000Vleck et al, 2000;Riou et al, 2010;Angelier Fig.…”

This article is part of a Special Issue "Parental Care". In vertebrates, adjustments of physiology and behavior to environmental changes are often mediated by central physiological mechanisms, and more specifically by hormonal mechanisms. As a consequence, these mechanisms are thought to orchestrate life-history decisions in wild vertebrates. For instance, investigating the hormonal regulation of parental behavior is relevant to evaluate how parents modulate their effort according to specific environmental conditions. Surprisingly and despite being classically known as the 'parental hormone', prolactin has been overlooked in birds relative to this context. Our aim is to review evidence that changes in prolactin levels can mediate, at least to some extent, the response of breeding birds to environmental conditions. To do so, we first examine current evidence and limits for the role of prolactin in mediating parental behavior in birds. Second, we emphasize the influence of environmental conditions and stressors on circulating prolactin levels. In addition, we review to what extent prolactin levels are a reliable predictor of breeding success in wild birds. By linking environmental conditions, prolactin regulation, parental behavior, and breeding success, we highlight the potential role of this hormone in mediating parental decisions in birds. Finally, we also review the potential role of prolactin in mediating other life history decisions such as clutch size, re-nesting, and the timing of molt. By evaluating the influence of stressors on circulating prolactin levels during these other life-history decisions, we also raise new hypotheses regarding the potential of the prolactin stress response to regulate the orchestration of the annual cycle when environmental changes occur. To sum up, we show in this review that prolactin regulation has a strong potential to allow ecological physiologists to better understand how individuals adjust their life-history decisions (clutch size, parental behavior, re-nesting, and onset of molt) according to the environmental conditions they encounter and we encourage further research on that topic.

“…Male and female king penguins, Aptenodytes patagonicus, take turns of many days to weeks alternating the incubation of the sole egg and prolactin levels begin to elevate from baseline levels during the courting and copulation period, with a further increase during the incubation and chick rearing period [24]. Male scrub-jay breeders (Aphelocoma c. coerulescens), canaries (Serinus canarius), white-crowned sparrows (Zonotrichia leucophrys), song sparrows (Melospiza melodia) and European starlings (Sturnus vulgaris) all have elevated levels of prolactin prior to the hatching of the young regardless of whether the males participate in incubation [5,[29][30][31][32]. It has been hypothesised that increases in prolactin levels may be mediating the feeding of incubating females or of young nestlings [29] and, therefore, that they are not solely a response to stimulatory cues from the eggs or chicks.…”

Hormonal changes during non-maternal infant care have been demonstrated in many cooperatively breeding bird species, some monogamous rodents and two species of New World primates. Coevolution of hormones and social traits may have provided for the different breeding systems that occur today. Several hormones have been shown to covary with the breeding systems of vertebrates. Elevated levels of the hormone prolactin with male parenting behaviours are common to many birds, rodents and the callitrichid monkeys Callithrix jacchus and Saguinus oedipus. In birds, prolactin may be elevated in both male and female breeders during various stages of nest building, egg laying, incubating and feeding of young. Testosterone levels appear to have an inverse relationship to prolactin levels during infant care in birds and rodents, but this relationship has not been examined for primates. In cooperatively breeding birds, helpers who remain at the nest also have elevated levels of prolactin when displaying parental care behaviours. Prolactin levels are elevated in helper callitrichid monkeys during the postpartum period. Monogamous male rodents demonstrate elevated prolactin levels with parental care behaviour but, in contrast to the birds, the mechanisms mediating prolactin increase appear to differ for male and female rodents. Two factors may influence male parental behaviours and hormonal changes: stimuli from the pregnant female and stimuli from the newborn pups; whereas maternal behaviours are influenced by the maternal hormones of the female and the pup stimuli. An experiential factor may also influence male parental behaviours. Neuropeptides such as oxytocin and vasopressin appear to be involved in male rodent parental care and there may be an interaction between a series of hormones and neurosecretions and stimuli from mates and pups. Studies of Saguinus oedipus, the cotton-top tamarin, suggest that prolactin levels are responsive to stimuli from contact with infants and the level of infant care experience influences the levels of prolactin with male infant care. Father tamarins also have elevated levels of prolactin before the birth of infants suggesting that cues from the pregnant female are important. Prolactin’s role in parental care may have evolved from prolactin’s role in other reproductive functions. Hormonal regulation of non-maternal care may occur due to a complex interaction of many hormones and neurotransmitters. Studies described here should provide the impetus for further work on parental care hormones in a wide variety of primates.
