The Sunflower Suet Ball Feeder fits three balls for winter feeding of wild birds. The dome shaped front slides easily away for cleaning and filling, and snaps tightly shut to secure the balls inside. In the Lower Mainland of British Columbia, this feeder will attract chickadees, juncos, flickers, hairy woodpeckers, downy woodpeckers, nuthatches, jays, and more. Suet is full of the fatty, energy-rich foods wild birds need in the winter to help cope with the cold and to supply healthy food when insects are not present and there are no berries to be found. Use with standard sized suet balls.
