Studio Tolvanen’s Mika and Julie Tolvanen have been observing birds for years, often through their dining room window while having breakfast. Interested in the birds’ feeding habits, the designers created prototypes of the feeder to see what would work. Bird Silo is designed particularly for species that feed vertically, and therefore it is recommended to fill it with sunflower seeds or peanuts, food that is suitable for birds like chickadees, blue tits, titmice, nuthatches, finches and woodpeckers. Bird Silo feeders are made in Finland.
