This Coveside box is dimensioned for Western and Mountain bluebirds, whose slightly larger build calls for a 1.5625-inch entry hole rather than the 1.5-inch opening used for eastern birds. The thick 1-inch white pine insulates against heat and cold, and a built-up entry serves as a predator guard against reaching paws.
Set it on a pole or post in open country, facing the hole toward a nearby perch tree, and space boxes along a trail if you are managing several. Ventilation slots and drainage holes keep the interior dry, while the side panel opens for quick monitoring and end-of-season cleaning.
Coveside has been handcrafting bird habitats in Maine for decades, using sustainably sourced wood and field-proven nest-box designs trusted by bluebird trail monitors.
