EcoTough Wren & Chickadee House from Wild Birds Unlimited
The WBU EcoTough Bluebird House
For smaller cavity nesting birds, the EcoTough Wren & Chickadee House from Wild Birds Unlimited is a favorite with a unique two-way opening system. The side opens for cleaning, and the roof opens to monitor the nesting activities periodically. This sturdy birdhouse also features ventilation and drainage slots, and like other WBU EcoTough products, the Wren & Chickadee House is constructed with environmentally friendly high-quality products made from recycled plastic. WBU also offers a similar larger EcoTough Bluebird House.
