Habitat modification for birds involves which of the following?

• A. Limiting a bird's water, food, or shelter
• B. Spraying nests
• C. Netting roosts
• D. Bait-type pesticides

Answer: (A)

Habitat modification means changing the environment to make it less inviting for birds by reducing the resources they need to survive and reproduce. If water sources, food supplies, or shelter are limited, birds are less likely to settle, nest, or roost in that area, which lowers their presence over time. Practical examples include securing garbage and spilled feed to cut off food, eliminating standing water that attracts birds, and removing or altering sheltered roosting or nesting sites around buildings. This approach targets the conditions that support a bird population rather than killing birds or blocking access directly. The other options are actions that directly target birds or their nests (spraying nests), physically blocking access to roosting areas (netting roosts), or using toxic baits (bait-type pesticides). Those are active control or exclusion methods, not habitat modification.
