Premium Cedar Bluebird House for Outdoor Use - Natural Wooden Birdhouse for Bluebirds, Finches, Wrens & Hummingbirds (1-Pack) - Perfect for Backyard Birdwatching & Garden Decoration

I just installed three of these within a forested area, fully furnished, ready to move-in, with straw beds. Stashed a little extra straw outside atop the units, between the tree and house in case it gets a little chilly at night. Two fresh coats of Sherwin Wiliams waterbased decking stain, should ensure your feathers remain warm, dry and cozy!This is your de facto good all natural material bird house.Some short-comings:1) No instructions, but easily learned, especially when assembling multiple bird houses.2) Bottom screen is cut extremely short of the width/depth of the bottom of the bird house. To fix, buy your own quart inch galvanized/stainless hardware cloth, and cut to proper width/depth. Workaround, can also squish the sides of the existing mesh, canting the corners into the grooves. From pictures, looks like the original bird house design was more narrow, while subsequent models are wider, more depth; hence the screen is likely overstock from older models.3) No sealant either provided, nor recommended. I'm thinking, a clear translucent water based decking stain on the exterior and a shellac (or same water based decking stain) on the inside. Although cedar is supposedly long lasting, probably best applying an exterior (water based) coating for weather protection and interior sealant for repelling moisture/mildew.4) Not really depicted, all four sides should like sit flush with the ground/bottom, providing a slight quart inch gap at the top of the front board and roof. Gap is likely for controlling moisture.5) The assembled unit can be mounted using a ~12 inch drill bit extension with additional decking screws, very loosely attached to a tree or preferably 4x4 post or wall. I opted using ~3.5 inch decking screws, one at the top exterior and one inside on the bottom, leaving ~1 inch for tree growth. The screw at the top on the exterior face will readily show whether the clearance from tree growth has been exceeded. Then inserted the screen atop the excess of the interior bottom, providing more support for the screen.
