A bird feeder that is functional sculpture for the modern yard, the Bird Silo is designed so that its only impact on nature is feeding the birds. The whole life-cycle of the product was considered. Made from 100% recycled plastic (even the rope is 100% recycled), the specialty feeder attracts birds who prefer to eat while clinging vertically. Common diners include chickadees, titmice, nuthatches, and woodpeckers. The vertical design deters house sparrows and pigeons, who can sometimes be pushy and dominate feeders.
