Abstract
Reproduction inhibitors are intended to maintain or control a population at a desired level; toxicants aim at elimination of the population. Azocosterol hydrochloride (SC-12937; 20,25-diazocholestenol dihydrochloride) is a long acting inhibitor of ovulation in the pigeon (Columba liyia) by interfering with cholesterol synthesis and egg yolk formation. Corn impregnated with SC-12937 at the 0.1% level by weight and fed for 10 days has been found to inhibit or diminish reproduction for 5-6 months. Population turnover rate, mortality and longevity of the feral urban pigeon are also discussed.
