The aim of this study was to determine in the ring dove, the effects of aromatase inhibition on the expression of aggressive courtship and nest-soliciting behaviours in relation to the distribution of cells containing immunoreactive androgen (AR) and progesterone (PR) receptor in the hypothalamus and pituitary gland. Isolated sexually experienced ring doves were transferred in opposite sex pairs to individual breeding cages, and then injected with the aromatase inhibitor, fadrozole (four males…

Courtship interactions stimulate rapid changes in GnRH synthesis in male ring doves
TLDR
It is suggested that this increase in GnRH synthesis is necessary to support the extended period of HPG axis activation that is seen in this species during the 5-10 day period of courtship and nest building activity.
Seasonal changes in aromatase and androgen receptor, but not estrogen receptor mRNA expression in the brain of the free‐living male song sparrow, Melospiza melodia morphna
TLDR
Aromatase expression in the ventromedial nucleus of the hypothalamus (VMH) was higher during breeding and non‐breeding compared with molt, suggesting that the VMH may play a role in the estrogen‐dependent regulation of aggression in this species.

TLDR
Analysis of circulating hormone levels and gene expression of steroid hormone receptors and aromatase in a captive population of barred buttonquails suggests that increased neural sensitivity to androgens could be involved in the mechanisms mediating sex-role-reversed behaviours.
Concentrations of the adrenocorticotropic hormone, corticosterone and sex steroid hormones and the expression of the androgen receptor in the pituitary and adrenal glands of male turkeys (Meleagris gallopavo) during growth and development.
TLDR
The results will expand the knowledge of the role of steroids in the development of the reproductive system of turkeys from the first month of age until maturity and suggest that AR expression in LH-producing pituitary cells is determined by the phase of development.
Neuroendocrine Regulation of Reproductive Behavior in Birds
This chapter reviews the neural and endocrine bases of reproductive behaviors in birds with a particular focus on the role played by gonadal sex steroid hormones in the regulation of sexual…
Acute and chronic effects of an aromatase inhibitor on pair-maintenance behavior of water-restricted zebra finch pairs.
TLDR
The data suggest that in water-restricted zebra finches, local synthesis of testosterone and estradiol in the brain may support the expression of pair-maintenance behaviors, and suggest that pair- maintenance behavior in non-breeding zebrafinches is not promoted by est radiol acting via either non-genomic or genomic mechanisms.
Pituitary Aromatase P450 May Be Involved in Maintenance of the Population of Luteinizing Hormone-Positive Pituitary Cells in Mice
TLDR
The findings suggest that the local production of estradiol mediated by pituitary aromatase is necessary for the regulation of LH-positive gonadotropic cells, exerting an autoparacrine inhibitory regulation.
Hormonal Regulation of Avian Courtship and Mating Behaviors
TLDR
This chapter defines courtship behaviors as those occurring between a male and a female at close proximity and that persuades a member of the opposite sex to copulate.
Pattern of aromatase mRNA expression in the brain of a weakly electric fish, Apteronotus leptorhynchus
TLDR
The findings of this study support a role for aromatase activity in reproduction, but no direct role in electric signaling behavior in non-breeding fish, and provide information on behaviors and neural circuits that are potentially affected by local estradiol production in A. leptorhynchus.
Hormones and the neuromuscular control of courtship in the golden-collared manakin (Manacus vitellinus)
TLDR
The behavioral neuroendocrinology of this male's courtship is studied, combining field behavioral observations with anatomical, biochemical and molecular laboratory-based studies to highlight the value of studying non-traditional species to illuminate physiological adaptations and stimulate future research on other species with complex behaviors.

Aromatase inhibition reduces specifically one display of the ring dove courtship behavior.
TLDR
The hypothesis that aromatase specifically modulates the nest soliciting display in intact male ring doves is supported and further evidence for separate hormonal control of different courtship displays in this species is provided.
Sex steroid communication in the ring dove brain during courtship.
TLDR
The increase in PR-ir staining intensity in AR-ir neurons in courting birds suggests that this progesterone-dependent termination of aggressive courtship display in males occurs at the receptor level and may be orchestrated by central oestrogen.
Selective inhibition by progesterone of androgen-induced behavior in male ring doves (Streptopelia risoria).
TLDR
Progesterone, in the presence of the circulating androgen, virtually completely inhibited the occurrence of the bowing-coo.
Localization of Progesterone Receptor in Brain and Pituitary of the Ring Dove: Influence of Breeding Cycle and Estrogen
TLDR
Quantitative analysis demonstrated that the density of cell nuclei containing PR-ir in the POA, PPM, and PLH in brooding birds was significantly higher than in E2-treated doves or in birds at other stages of the reproductive cycle.
Differential effects of testosterone and oestradiol on male courtship in Barbary doves (Streptopelia risoria).
TLDR
Group of males that had shown either full courtship or courtship lacking nest soliciting were castrated and treated intramuscularly with testosterone propionate or oestradiol monobenzoate and tested for 16 successive days with females to study the possible endocrine factors underlying the development and maintenance of nest solicititing.
Androgen increases formation of behaviourally effective oestrogen in dove brain
TLDR
The findings indicate that the formation of behaviourally effective oestrogen in a specific brain target area is under hormonal control and suggest a role for this regulatory mechanism in the integration of courtship behaviour in the male dove.
Estrogen-progesterone regulation of nest-building and incubation behavior in ovariectomized ring doves (Streptopelia risoria).
TLDR
Combined estrogen and progesterone treatment was the most effective hormone regimen for eliciting both behavior patterns in females and also facilitated these behaviors in their untreated mates.
Effect of sex steroids on the reproductive behavior of castrated male ring doves (Streptopelia sp.)
TLDR
DHTP is behaviorally effective in this species, “aggressive’ courtship and “nest-oriented” courtship have different patterns of steroid specificity, and wing-flipping in intact males may result from conversion of androgen to estrogen by the brain.
Radioimmunoassay of plasma progesterone during the reproductive cycle of male and female ring doves (Streptopelia risoria).
TLDR
There was a significant positive correlation between progresterone concentration and follicular development and oviduct weight during courtship and there was no significant changes detected i n progesterone concentration during the cycle in males.
Formation of behaviorally effective 17 beta-estradiol in the dove brain: steroid control of preoptic aromatase.
TLDR
It is concluded that circulating androgen modulates preoptic aromatase activity, which is higher in males than females, and is decreased in both short (30 day) and long term (180 day) castrates, indicating that gonadal hormones maintain POA aromat enzyme activity.
