Bring the magnificent music of bluebirds into your garden while deterring threats to their home with this Coveside Sparrow-Resistant Bluebird House with Open Top. This intuitively designed box prevents sparrows from overtaking the roost, while giving bluebirds a habitat they can comfortably populate. Research indicates that bluebirds utilize a slot entry, whereas sparrows gravitate toward a round hole. This brilliant pine unit is responsibly sourced from aged eastern pine for a unique and eco-conscious dwelling, and its 4" long and 1.25" high, rectangular entry caters to the needs of these musical birds. A sizable roof angles downward to guard the inside of the home from rain and other elements easily. An included, 1.5" thick, pine block can be situated within the home to shrink its depth, discouraging sparrows while tailoring this unit even more to the roosting habits of bluebirds. Situated atop the roof is a black, plastic grid to prevent large bits of detritus as well as predatory threats. Use the included white, plastic cap to cover this opening, employing it instead as a shallow dish for mealworms or other caloric snacks. Triangular corners just below the gaps of the roof facilitate proper air flow and temperature regulation, and a metal latch allows you to lift the dwelling's front panel upward for regular nest checks and cleanings. This abode's rough hewn interior gives ample grip to nestlings looking to navigate out of the house, and this naturally beautiful item will weather to a striking gray tone with time and exposure to outdoor conditions for a charming transformation. Utilize the attached, back hanger to showcase this handy home against a post or wall, or pole mount it with a mounting bracket (not included). Keep the threat of unwanted sparrows away from fantastic bluebirds with this Sparrow-Resistant Bluebird House with Open Top. Made in the USA.
