As part of the Ultimate Renewable series of bird houses and feeders, the Woodlink Bamboo Contemporary Wren House is made entirely out of bamboo. Bamboo is fast-growing, incredibly durable, and naturally insect-, squirrel-, and weather-resistant, which makes it 1 of the most environmentally friendly and renewable resources around. Not only is it fully assembled and ready to hang, the Woodlink Bamboo Contemporary Wren House has a smaller, wren-sized entrance hole, which keeps larger, more aggressive birds out. It also has an easy-open side panel for quick and easy cleanings. The attached jute rope lets you hang this bamboo wren house from a tree branch. For best results, hang or mount the bird house about 5' high with the front facing east to southeast. Manufacturer model #: 29100.
