Behavioral effects of rapid changes in estrogen availability following an acute injection of estradiol (A) or of the aromatase inhibitor Vorozole™ (B). A. A single injection of estradiol (E2) performed 5, 15 or 30 min before the beginning of the behavioral test significantly increases the expression of sexual behavior measured here by the frequency of cloacal contact movements (CCM). B. Significant inhibition by a single injection of the aromatase inhibitor Vorozole™ performed 15, 30, 45 or 60 min before the beginning of the behavioral test of the expression of sexual behavior measured by the frequency of CCM. Control values for birds injected with the control vehicle solution are represented by the gray areas. Redrawn from data in [88] and [86]
