Agricultural pest management targeting birds, mammals, and reptiles that damage crops raises important welfare questions about the methods used and the scale of killing.
Agricultural vertebrate pest management creates welfare costs at large scale. Lethal bird control through shooting, trapping, and poison causes individual animal suffering. Secondary poisoning of predators (barn owls, kestrels) from rodenticide use extends the welfare impact beyond target species. The practical case against lethal control — that it requires continuous repetition as new individuals colonize cleared areas — aligns with the welfare case: non-lethal deterrents that modify habitat or behavior are more durable and more humane. Integrated pest management approaches that minimize lethal control while protecting crops are the welfare-positive direction for agricultural pest management.
