Abstract
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.
