We build our nest boxes to encourage wildlife to visit and make a home for themselves in your garden. We use materials that we would like to find in our own homes, natural clay, non toxic glazes, sustainable bamboo, copper and brass. All the weatherproof Nest Boxes have removable perches, & can be opened for easy cleaning. We hope you and your feathered friends enjoy! Handcrafted from natural stoneware and sustainable bamboo, the Firefly Nest Box is available in 3 finishes. Perfect to attract barn swallows, the Firefly can be mounted in colonies. Eating insects and performing aerobatics in the air, barns swallows are some of our favorite birds. Place the nest box in a location with a clear open view.
