This Bluebird Nesting Box - Hunter Green & Ivory, by Rubicon is approved by the North American Bluebird Society (NABS). This Two-toned Bluebird Nesting Box isn’t just a great bluebird house, it’s also great for the environment. Made from recycled milk jugs, the plastic lumber construction helps keep plastic out of landfills and prevents deforestation and destruction of natural bluebird habitats. This bluebird house’s design also features many details that make it a perfect choice for your bluebirds: a ventilation slot under the roof helps regulate the temperature to a safe level for nestlings; the sloping roof, floor, and inside drainage hole keep the house dry and comfortable; and a predator guard reinforces the perchless entrance hole to deter intruders. The incredibly durable plastic lumber will not fade, crack, peel, chip, rot, or warp with time. Unscrew the lock and slide the front panel off to observe nest activity and discard deserted nests. Use the included screws to mount the NABS Approved Nesting Box to a tree or post. Made in the USA. Unconditional lifetime guarantee.
