ABSTRACT
Chemicals are used to control bird populations when they cause damage to crops, stock-food, buildings and other structures, and when they are hazards at places such as airports, public parks, golf courses, and rubbish dumps. They include lethal toxicants (avicides) and stressing agents, and nonlethal immobilizing agents, repellents, and reproductive inhibitors. Lethal methods of control attempt to reduce bird numbers, whereas nonlethal methods generally attempt to modify bird behavior without causing mortality, as a means of reducing damage.
