Final answer:
Predatory birds such as hawks, falcons, and owls are used to control unwanted birds on a property by acting as natural deterrents to smaller, pest bird species. This method is a form of biological pest control that can be beneficial for crops and the environment.
Step-by-step explanation:
Types of birds used to control unwanted birds on a property often include predatory birds such as hawks, falcons, and owls. These birds act as natural deterrents to smaller, pest bird species. Using birds of prey for pest control is a method that utilizes the natural food chain to manage pest populations, as opposed to mechanical means like trapping or chemical means such as the use of pesticides.
Moreover, promoting natural predators and preserving their habitats can have economic benefits and contribute to a healthier environment, as evidence shows that birds can help control insect populations which, in turn, protects crops. Entomologists even successfully used biological control with parasitic wasps for pest management in Beijing, demonstrating the potential of biological solutions over chemical ones.
Thus, implementing avian control through the use of birds of prey can be an effective strategy for pest management, achieving pest control while also safeguarding the ecosystem.
