Anavicide is any substance (normally achemical) used to killbirds.

Commonly used avicides includestrychnine (also used as rodenticide and predacide),DRC-1339 (3-chloro-4-methylaniline hydrochloride, Starlicide) andCPTH (3-chloro-p-toluidine, the free base of Starlicide),Avitrol (4-aminopyridine) andchloralose (also used as rodenticide). In the past, highly concentrated formulations ofparathion in diesel oil were sprayed by aircraft over birds' nesting colonies.
Avicides are banned in many countries because of their ecological impact, which is poorly studied. They are still used in the United States, Canada, Australia and New Zealand. The practice is criticized by animal rights advocates and those who kill birds with guns and traps. Pigeon fanciers sometimes poison problematic birds of prey, even in countries like Russia and Ukraine where avicides are illegal.[1]
