About Turquoise Copper Mushroom Bird Feeder by Browersmith Copperworks The Turquoise Copper Mushroom Bird Feeder is from the Verdigris Collection. The blue and turquoise colors are created using only natural ingredients, absolutely no chemicals were applied to these bird feeders. This handmade copper bird feeder is 10″ tall overall with an additional 5.5″ solid copper hook that is included. It is naturally resistant to bacteria and viruses which makes it extremely friendly to our hungry woodland friends. The bottom dish is 9″ in diameter and 2″ deep with small holes to allow rain water to drain in case it blows in. This bird feeder holds approximately 1.5 lbs of oiled sunflower seed (6 cups). The top is larger than the bottom to shed the elements and measures 10″. An original Browersmith Copperworks design, each hand sculpted feeder is cut and hand forged to it’s shape. No production tools are used to create these pieces and each one is individually handmade. They are then cleaned showing their own color variations and nuances. A finish is not applied so the patina will gradually age to a gorgeous natural copper-brown with hints of blues and green over the years.
