The NEW Clipper BlueBird home from Byer is part of our beautifully handcrafted Mango Tree Collection. The Clipper is sculpted from the harvested trunks of the Mango tree. The homes feature a high-quality polyurethane multi-coat finish to ensure longevity in the elements. The roof of the clipper is removable for seasonal cleaning; and the hole size is 1 1/2 inch, the ideal size for Bluebird's. The home also provides ample depth for comfortable nesting, and drainage holes in the bottom, to keep the nest dry. There may be color variances due to natural material.
