We take Steel from old Saw Blades that is actually a hardened steel and we cut this pattern specifically for bluebird houses.
This is primarily to keep squirrels and other critters from chewing wider openings. It’s got a nice heavy weight to it. If you prefer a slower cheaper method of shipping we can arrange that, but this is for a flat rate priority envelope, which they’re charging $8.90 right now if you want multiples, we can add them into the same envelope for the same shipping price
When our birds get back into aggressive nesting, we will photograph them properly, but they love their home.
