Bests & Worsts Reviews from Amazon

I bought these for bluebirds and tree swallows and they are very well constructed. I mount these in a field by attaching a conduit footer (hardware store) to the bottom of the box with four wood screws that do not go through the floor. I get electrical conduit pipe and cut it into 6 foot lengths. This gets placed in an old paint bucket of concrete, which is buried in my field. It's pretty simple really. Once the concrete is buried you attach the box. As you can see in my photos I add perches which they seem to like. A note about house sparrows. This box is NOT sparrow resistant, none of them are. I've tried PVC and slot-type boxed and house sparrows with attempt to use them all. They tried nesting in these as well but I trapped them with an in box trap and removed them (Google Van Ert traps). House sparrows are a non-native invasive species that will attack and kill our native bluebirds, chickadees, and tree swallows. They are not protected by law. Once the house sparrows have been removed tree swallows and bluebirds moved right in! They've built nests and once the female starts egg sitting I will attach a sparrow spooker which helps deter sparrow "invasions". I remove this after the little ones have fledged. If you're not prepared to take these steps you might just end up with house sparrows or end up with in box carnage. UPDATE: I've added a picture of the box with a "sparrow spooker" attached to it. These can ONLY put be put up after egg laying begins and must be taken down after the young ones leave the nest. Google for proper directions. As you can tell being a bluebird landlord is quite a bit of work but it's only one month a year and it's rewarding to help our native species. Feel free to ask any questions. UPDATE March 2023: ordered 4 more of these and the backs are split and they make the roof from 2 pieces of wood so they won’t be water tight. What was once a great item is now almost unusable.
