The perch birdfeeder is made of white earthenware. The hang-anywhere birdfeeder is perfect for modern gardens or urban fire escapes. It's 7″ in diameter, hangs from a 36″ vegetable tanned leather cord and holds about 2 cups of bird seed. It's easy to wash with soap and water or you can throw it (gently) in the dishwasher. Contact us if you need a new or longer leather cord. This birdfeeder can be outside all year long, although if you live in a climate with rough weather, your birdfeeder will last longer if you bring it in in the winter.
