Gave 30 ovariectomized and 6 intact female ring doves daily injections of 0, 5, 25, 50, or 100 mg of estradiol benzoate (EB) in .1 cc of sesame oil. Characteristic female behavior patterns in response to male courtship were abolished by 2-stage bilateral ovariectomy. Depending on the dose level, these behavior patterns recovered after systemic EB treatment. At a dosage of 50 mg, full recovery of female behavior patterns, with the exception of nest building, was observed. The order of recovery of the behavior patterns resembled the order of appearance in the normal breeding cycle, suggesting a causal relation between the level of estrogen and the normal display of specific behavior patterns. At a higher dose (100 mg), the oviduct weight was stimulated further while behavioral effect was suppressed. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
