My bird feeders have a lot of features to keep birds happy — drainage holes and awnings to keep bird seed dry, natural cedar perches for easy landing, and the bottom edge of the opening is left unglazed so little bird feet can grip more easily. Hand-washing is recommended to preserve the life of the glaze, but these can also go in the dishwasher, making cleaning them super easy. All bird feeders are approximately 5” wide and 7 - 9” tall. Stoneware can be left outside year-round.
