Bird droppings can cause significant damage to outdoor bronze sculptures, leading to corrosion and aesthetic degradation. To prevent this, several effective methods can be employed. First, applying a protective wax or lacquer coating creates a barrier that repels moisture and acidic bird waste. Regular reapplication is essential for long-term protection.

Another approach is installing physical deterrents, such as spikes or nets, around the sculpture to discourage birds from perching. Ultrasonic devices or visual deterrents like reflective tape can also deter birds without harming them.

Regular cleaning is crucial; gently washing the sculpture with mild soap and water removes droppings before they cause harm. Avoid abrasive materials that could scratch the bronze. For heavily soiled areas, consult a professional conservator.

Lastly, strategic placement of the sculpture—away from trees or ledges where birds roost—can minimize exposure. Combining these methods ensures your bronze artwork remains pristine for years to come.
