Give your purple martin colony their own castle in the sky with the Starling Resistant 28 Room Purple Martin House.  SREH (starling resistant entrance holes) is a tried and proven method for helping to eliminate the pesky European Starling. Tests have shown the entry holes are 99.8% effective in achieving this. This hole is cut to an exact height restricting starling entry but allowing safe entry for the Purple Martin which gives it a greater sense of security.

 

The SREH Mansion features include all cool aluminum and stainless steel construction, 3 reflective roofs, ceiling panels for proper ventilation, porch dividers, hinged clean out doors, guard rails, 3 top perch rails (not shown in picture), and an all aluminum base plate. Each room 6" x 6". Requires a Heavy Duty Pole (not included).
