Modifying Lonestar Alamo Nest Trays

The following photos illustrate a test nest tray that I will be using on some of my compartments this Spring to see whether the martins will adjust to an ante-room and bedroom nest tray adaptation. The entrance to the bedroom is 2 1/8 inch wide and is offset to the regular outside entrance to prevent any predator from reaching in. Secondly, the young will be segregated to the back room by the tall wood divider.  Predators will not be able to see the young unless they wander to the front part of the tray.
