A good bluebird box should be more than just a cavity for a bird to build a nest in. It should be easy to monitor, easy to clean, and provide a safe nesting site. This one has it all! **APPROVED BY THE NORTH AMERICAN BLUEBIRD SOCIETY.** It is very easy to monitor and clean this Eastern Bluebird house with flip down front panel. A fledgling ladder below the exit gives the bluebirds additional traction. There is plenty of ventilation just under the roof line and drainage holes on the bottom to keep the nest dry. It is a very well made box! An information sheet is included. Nest Box Features: Recycled plastic and stainless steel screw construction, flip-down front panel, 1½” entry with copper portal to keep out larger birds, grooved fledgling ladder below exit, and excellent drainage and ventilation.
