Protect your nesting bluebirds from competing speciesWatch your bluebirds fledge this year. Aggressive House Wrens won’t enter a nesting box when they can’t see the entry hole. The Wren Shield is made from solid blue recycled plastic to block the view of the entrance from House Wrens. The Wren Shield is easy to use: Unscrew the roof to see when the first or second egg has been laid, then hang the Wren Shield in front of the entrance. Bluebirds can easily enter and exit the nestbox and may continue to lay eggs. Once the hatchlings are between 4 and 7 days old, position the Wren Shield in the upright position so as not to interfere with fledging. Durable tan and blue recycled plastic with built-in ventilation and drainage. 5-3/8 x 9-3/4 x 11-3/8 inches tall. 1-1/2 inch entry hole with inner predator guard Enjoy watching all of your bluebirds fledge this year Features easy to use Wren Shield to keep out House Wrens Now includes lower eye hook for easy cleanout Made in the USA, available exclusively at Duncraft
