Copper Bird Feeders
Copper is a great material to use in your bird feeders. Bird feeders must suffer the outside elements, and too many times natural wood or painted feeders don't stand up to the weather and the sun. Copper will tend to last much longer, and will look great doing it. With brushed copper the finish will keep the bright new penny look for much longer, but even with exposed copper the natural patina that forms is attractive and will keep that natural look for years to come.
Copper has been used for many years on construction ranging from single family homes to the centuries old churches. It withstands the test of time, and is sturdier than many other construction materials. If you have a problem with pests like squirrels, you will find that they can't destroy these feeders as easily as wooden feeders.
The patina that forms from copper that has been exposed to the weather is often referred to as verdigris, and copper based compounds like brass will also form patina. Many bird feeders also come in a verdigris variation.
