Bird droppings can cause significant damage to bronze sculptures, leading to corrosion and aesthetic degradation. To protect these valuable artworks, consider the following effective strategies:

1. Install Physical Barriers: Use nets, spikes, or wires around the sculpture to deter birds from landing. These barriers are non-invasive and highly effective.

2. Apply Protective Coatings: Wax or lacquer coatings create a barrier between the bronze and bird droppings, making cleanup easier and preventing chemical reactions.

3. Use Bird Deterrents: Reflective tapes, decoys, or ultrasonic devices can scare birds away without harming them or the sculpture.

4. Regular Cleaning: Promptly remove droppings with gentle cleaning solutions to prevent long-term damage. Avoid abrasive tools that could scratch the surface.

5. Strategic Placement: Position sculptures away from trees or ledges where birds frequently perch to minimize exposure.

By combining these methods, you can preserve the beauty and integrity of bronze sculptures for years to come.
