“…Recently, the DAergic and mesotocinergic systems have been reported to be involved in the rearing behavior of birds (Chokchaloemwong et al, 2013;Thayananuphat et al, 2011). In addition, DAergic neurotransmission is an important regulator of the VIP/PRL system, which plays a significant role in the neuroendocrine reorganization that establishes and maintains maternal behaviors in the native Thai chicken (Chaiyachet et al, 2013a,b;Prakobsaeng et al, 2011).…”

“…Rearing hens remained with the chicks, showed aggressive behavior, and emitted a high-pitched vocalization when they were approached by the males or by humans. They fluffed their feathers, crouched over the chicks to encourage them to go under the wings, and used various types of vocalization to guard and feed the chicks (Edgar et al, 2011;Opel and Proudman, 1989;Thayananuphat et al, 2011). R and NR hens were sacrificed at different time points (day of hatch, and 4, 7, 10, 14, 17, 21, 24, and 28 days after hatch; 6 hens/time point/group) either they started to rear their chicks or after the chicks were removed.…”

“…Because mesotocin, the avian homolog of oxytocin, is produced in this same region of the avian hypothalamus [66–69] it would be fruitful to investigate the possibility that the neurons in the dove PVN that exhibit increased STAT5 phosphorylation are mesotocinergic. Indirect support for prolactin involvement in mesotocin expression is provided by a recent series of studies by Thayananuphat and colleagues [69] in turkeys. These authors found that the number of mesotocin-ir neurons in the PVN increase when plasma prolactin levels are elevated during late incubation.…”

Increased STAT5 signaling in the ring dove brain in response to prolactin administration and spontaneous elevations in prolactin during the breeding cycle

Prolactin acts on target cells in the central nervous system (CNS) to stimulate behavioral changes associated with parental care in birds, but the signaling mechanisms that mediate these actions have not been characterized. In mammals, the Janus Kinase 2-Signal Transducer and Activator of Transcription 5 (JAK2-STAT5) signaling pathway mediates many of the actions of prolactin. To assess the importance of this pathway in prolactin-sensitive target cells in the avian brain, we measured changes in activated (phosphorylated) STAT5 (pSTAT5) in the forebrain of female ring doves sampled as plasma prolactin levels change during the breeding cycle and in prolactintreated, non-breeding females. The anatomical distribution of cells exhibiting pSTAT5 immunoreactivity in dove brain closely paralleled the distribution of prolactin receptors in this species. The density of pSTAT5 immunoreactive (pSTAT5-ir) cells were highest in the preoptic area, the suprachiasmatic, paraventricular, ventromedial hypothalamic nuclei, the lateral and tuberal hypothalamic regions, the lateral bed nucleus of the stria terminalis, and the lateral septum. Mean pSTAT5-ir cell densities in these eight brain areas were several fold higher in breeding females during late incubation/early post-hatching when plasma prolactin levels have been observed to peak than in non-breeding females or breeding females sampled at earlier stages when prolactin titers have been reported to be lower. Similar differences were observed between prolactin-treated and vehicle-treated females in all three of the forebrain regions that were compared. We conclude that JAK2-STAT5 signaling is strongly activated in response to prolactin stimulation in the ring dove brain and could potentially mediate some of the centrally-mediated behavioral effects of this hormone.

“…In mammals, both VP and OT play important roles in maternal care (Pedersen et al, 1982; Bosch and Neumann, 2008), but the possibility of convergent functions in birds has only recently been addressed, with the findings that 1) brooding of poults by turkey hens is abolished by intraventricular infusions of an OT receptor antagonist, and 2) this occurs in association with elevated c-fos expression in MT neurons of the PVN and ventral SON (Thayananuphat et al, 2011). Thus, in birds as in mammals, the basic social and reproductive functions of MT/OT have likely been expanded to include the modulation of direct offspring care.…”

Of the major vertebrate taxa, Class Aves is the most extensively studied in relation to the evolution of social systems and behavior, largely because birds exhibit an incomparable balance of tractability, diversity, and cognitive complexity. In addition, like humans, most bird species are socially monogamous, exhibit biparental care, and conduct most of their social interactions through auditory and visual modalities. These qualities make birds attractive as research subjects, and also make them valuable for comparative studies of neuroendocrine mechanisms. This value has become increasingly apparent as more and more evidence shows that social behavior circuits of the basal forebrain and midbrain are deeply conserved (from an evolutionary perspective), and particularly similar in birds and mammals. Among the strongest similarities are the basic structures and functions of avian and mammalian nonapeptide systems, which include mesotocin (MT) and arginine vasotocin (VT) systems in birds, and the homologous oxytocin (OT) and vasopressin (VP) systems, respectively, in mammals. We here summarize these basic properties, and then describe a research program that has leveraged the social diversity of estrildid finches to gain insights into the nonapeptide mechanisms of grouping, a behavioral dimension that is not experimentally tractable in most other taxa. These studies have used five monogamous, biparental finch species that exhibit group sizes ranging from territorial male-female pairs to large flocks containing hundreds or thousands of birds. The results provide novel insights into the history of nonapeptide functions in amniote vertebrates, and yield remarkable clarity on the nonapeptide biology of dinosaurs and ancient mammals.
