This beauty now features an extended roof for extra protection. Thousands are in continuous, year "round service, attracting both clinging and perching birds. The original bronze No/No Feeder is constructed totally of metal. No wood and no plastic are used. The feeder has a unique textured finish, lasts for years, feeds 10-15 birds at once, and holds over two and a half (2.5) pounds of black oil sunflower seeds, the most popular seed for wild birds. The feeder never needs to be cleaned, but it is dishwasher safe, if you insist! The No/No feeder"s simple wire mesh design helps to protect birds from avian diseases and is a collapsible, wire basket.
