NO/NO = No plastic, No wood. The premium metal construction of the NO/NO Red Seed Ball Wild Bird Feeder stands up against squirrels and other small animals that may try to access birdseed. Holds 6 cups of black oil sunflower seed, the most popular seed for wild birds. The seed ball measures 6 inches in diameter, and open mesh wire design welcomes clinging birds while keeping water from pooling in the feeder. This means less soggy, wasted birdseed and healthier birds! Attached handle makes hanging from a branch, shepherds hook, or other setup very quick and easy. Beautiful red finish is the perfect touch for every yard, patio, and garden.
