“…In this study, we were unable to distinguish between magnocellular and parvocellular AVT-ir cell populations within the PVN. Baseline plasma osmolality in this study was similar to that measured in other bird species [Gray and Erasmus, 1989;Gray and Brown, 1995;Goecke and Goldstein, 1997;Goldstein and Bradshaw, 1998;Saito and Grossmann, 1998;Sharma et al, 2009] and in curve-billed thrashers [Vleck, 1993], and we found neither an association between AVT-ir in the PVN and plasma osmolality nor a population difference in plasma osmolality. However, plasma osmolality was positively correlated with AVT-ir ME staining in urban but not in desert birds.…”

The neuropeptide arginine vasotocin (AVT: the avian homolog of vasopressin) has numerous functional roles including mediating social behaviors, coregulating the adrenocortical stress response and maintaining water balance. These functions of AVT make it susceptible to environmental influence, yet little is understood concerning the variation in the AVT system across habitats. In this study, AVT immunoreactivity was compared between male curve-billed thrashers, Toxostomacurvirostre, from native Sonoran Desert locations and those within the city of Phoenix, Ariz. Previous research found that urban thrashers are more responsive to territorial intrusion, secrete more corticosterone (CORT) during capture stress, and they may also have greater access to water than desert counterparts. Variation in AVT immunoreactivity was also related to levels of plasma CORT and osmolality, and with behavioral responses to a simulated territorial intrusion. Birds from these two habitats showed different AVT immunoreactive patterns in two brain regions: the paraventricular nucleus of the hypothalamus and the medial bed nucleus of the stria terminalis (BSTM), a part of the limbic system. Immunoreactive AVT within the paraventricular nucleus was associated with plasma CORT levels in urban, but not desert, birds, but no such association with osmolality was observed in birds from either habitat. The total number of BSTM AVT-immunoreactive cells was related to a decreased responsiveness to territorial intrusion. These data suggest that divergence in the AVT system between urban and desert thrashers may help explain observed differences in both the adrenocortical stress response and territorial behavior between populations. Whether differences in water availability between habitats contribute to population differences in the brain AVT system is unknown.

“…Also, our results (Lazarevic et al, 2000), showed that sound have significant influence on change heterophil/lymphocyte ratio, which is one of imoprtant indicator of avian stress reaction (McFarlane and Curtis, 1989). According with our result, adrenal glends of birds are known to respond to stress condition by interrenal hyperplasia (Garren and Barber, 1955;Siegel, 1959;Feeman, 1970;Aire, 1980) and changes in interrenal cord and interrenal and chromafine ratio (Sharma et al, 2009).…”

The aim of this paper is to examine the effect of different sound stress duration on adrenal gland of broiler chickens of different age. The experiments were conducted on 90 HYBRO broiler chickens, divided into nine groups (each group consisting of 10 birds) by different age and lenght of sound stress duration. The chickens were exposed to sound stress in sound attenuated building using a fire alarm bell (95 dB) for stress sessions lasted 120 min every day. The histological structure of adrenal gland was analyzed by light microscopy. The results indicate that adrenal gland is sensitive on this kind of stress and sound as stressor could introduce organism in stress reaction. Adrenal glands of broilers exposed to sound stress characterized by marked hyperemia, hypertrophy of interrenal cells, smaller affinity for staining of chromaffin cells compared with control groups. According to our results, degree of histological changes of adrenal gland under the influence of sound stress depends on the length of exposure and age of chickens.

“…The VT2 also shows osmoregulatory properties (Cornett et al, 2003; Jurkevich et al, 2005; Jurkevich et al, 2008; Sharma and Chaturvedi, 2009; Sharma et al, 2009). The VT3 is an oxytocic receptor that is expressed in the brain and also the oviduct uterus, where it is regulated by estrogens and influences oviposition (Srivastava et al, 2007; 2008; Srivastava and Chaturvedi, 2010; Srivastava et al, 2010).…”

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.
