Same quality as the Coates Original Houses but SREH entrance holes are cut to an exact height restricting starling entry and giving Purple Martins greater security. This assembled house has 2 floors and 8 rooms. Tests have shown that the entry holes are 99.8% effective in restricting starling entry but allowing safe entry for the Purple Martin. This gives the birds a greater sense of safety and security. These mansions come complete with hinged doors for easy cleanout, porch dividers, ceiling plate, reflective roof, top perch, guard rails, and an all-aluminum base plate.
