How to Prevent Copper Bird Feeders From Rusting

Study the location where the bird feeder will be hung or attached to a pole. The more sunlight there is on the feeder, the greater the need for a sealant with UV ray-absorbing compounds formulated into it.

Look for anything that might cause abrasion to the surface of the bird feeder. For instance, birds landing and taking off will cause some abrasion with their bird claws. Look for tree branches or shrubs that might rub against the bird feeder especially in strong winds. Look for materials nearby that might pit the surface of the bird feeder in high winds like sand and grit. If the feeder needs abrasion protection, then after applying a sealant offering UV protection, apply a coat of lacquer over the dried sealant for a tougher protective finish.

Gather information on the air pollution levels. Pollutants in the air can break down the copper sealant coating and start attacking the surface of the copper. Apply more than one layer of a sealant to deter copper corrosion.

Study the humidity levels in the location where the bird feeder will be hung or mounted. A shade garden will be more humid than one that receives full sunlight. The amount of air circulation makes a big difference, as well. If the yard is enclosed with tall shrubs and trees, the air flow in the garden will be reduced and humidity levels will run higher. Look at drainage, too. Soil or gravel that drains off rain quickly will keep humidity levels down.
