The Birdhouse is especially attractive to wrens and designed to discourage other unwanted species from invading the nesting area. This high-quality house is constructed of natural decay-resistant cedar. Made of re-forested, kiln-dried, inland red cedar, this feeder weathers the elements and is assembled with rust-resistant zinc chromate screws (not nails) to withstand temperature changes. Fully assembled and easy to hang with attached cable from small branches or hooks.
