Abstract

A practical evaluation of the chemosterilant SC-12937 (20, 25-diazocholesterol dihydrochloride) as a reproductive inhibitor for feral common pigeons (Columba livia) was made by feeding wild, free-flying birds with wheat containing 0.1 percent by weight of the absorbed drug. Pigeons consumed sufficient wheat to supply each bird with approximate- ly 0.30 g of the drug in 11-16 days. In 2 isolated rural colonies in Missouri reproductive inhibition was nearly complete for 5 and 7 mo. respectively; in a small Missouri town it was 89 percent complete for 3 mo. and in 2 flocks in New York City where egress and ingress were high, recruitment of young was reduced 10 percent. Treatment in March and again in July on a city-wide basis is recommended for practical reproductive control.
