椋鸟（Sturnus vulgaris）已成为西部越冬范围北部养牛场的一个严重问题。 1963 年 1 月，对一种新型慢效杀鸟剂 3-氯对甲苯胺盐酸盐 (DRC-1339) 在内华达州的一个孤立的椋鸟种群进行了初步现场试验。将 10 磅经过 1% DRC-1339 处理的家禽颗粒撒在 2 英亩的牛饲养场中，使 2280 只椋鸟数量减少了约 75%。几乎所有被杀的动物都在2小时内上钩。被曝光后。大多数在 48 小时内死于昏迷，其中大约一半在栖息地。在该地段捕食的约 4% 的黑鹂 (Euphaguscyyocephalus) 也被杀死，但其他 7 种鸟类显然没有受到伤害。未发现二次危险。
Starlings (Sturnus vulgaris) have be-come a serious problem in cattle feedlots in the northern part of their wintering range in the West. The initial field trial of 3-chloro-p-toluidine hydrochloride (DRC-1339), a new slow-acting avicide, was made on an isolated starling population in Nevada in Jan., 1963. Ten pounds of 1% DRC-1339-treated poultry pellets, spread at a 2-acre cattle feedlot, reduced the population of 2280 starlings by about 75%. Almost all that were killed took the bait within 2 hrs. after it was exposed. Most died in a coma within 48 hrs, about half of them in the roost. Approximately 4% of the Brewer''s blackbirds (Euphagus cyanocephalus) that fed at the lot were also killed, but 7 other species of birds were evidently not harmed. No secondary hazards were noted.
