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 Chickadee hole size is 1 1/8 inch perfect for small cavity nesters. The home also features drainage holes in the bottom, to keep the nest dry. There may be color variances due to natural material.
