In pest bird control planning, which approaches are considered non-lethal management options?

• A. Exclusion or habitat modification
• B. Poisoning or killing
• C. Relocation only
• D. Breeding programs

Answer: (A)

Non-lethal pest bird management focuses on preventing birds from accessing or returning to a site without harming them. The most reliable and direct way to do this is through exclusion and habitat modification. Exclusion uses barriers that physically block birds from entering or perching—netting over open areas, screens on vents, bird spikes on ledges, and sealing gaps. Habitat modification reduces the site’s appeal or accessibility by removing attractants (like spilled or accessible food, exposed standing water, or easily used nesting spots) and by altering perching opportunities (trimming vegetation, removing roosting sites, changing lighting, and managing waste). When done thoughtfully and maintained over time, these strategies offer durable protection and align with wildlife protection rules.

Poisoning or killing is a lethal approach and not a non-lethal option. Relocation is non-lethal but often impractical or ineffective long term because birds may return or new birds move in. Breeding programs can influence populations but are not typically the primary non-lethal, site-specific solution for immediate damage; they’re more complex to implement and less immediately impactful for a specific problem site.
