Double the bluebird roosting options in your yard while deterring sparrows from nesting with these handmade Sparrow-Resistant Cedar Eastern Bluebird Houses by Prime Retreat. These 2, lasting cedar nest boxes wonderfully meet the needs of eastern bluebirds, but are unappealing to sparrows. Research done by the University of Kentucky found that bluebirds readily use a shallow home with a slot entry, both of which discourage sparrows from nesting. A 4" long and 0.75" tall slot on each home acts as an entry, and the overhang of each roof keeps the interior dry. Gaps below the roof line provide ventilation, and a 1.75" thick block of wood sits inside each cavity. This forms a shallow nesting area, deep enough for bluebirds but unpleasant for sparrows. Affix these homes to a wall, fence, or post using the included mounting tab and screw, and open the front panel upward for periodic nest checks. For a different look, place a mounting bracket (not included) on one home's base to pole mount it. The cedar construction naturally repels insects and moisture for many seasons of use, and the striking grain and knots showcase the beauty of natural timber. A burnt logo on the base of each front panel enhances the brown tones, creating a focal point. House melodic bluebirds without pesky sparrows using these Sparrow-Resistant Cedar Eastern Bluebird Houses. Made in the USA.
