Two floors. An attic tier. And a design philosophy centered on giving Purple Martins exactly what they need — generous compartment dimensions, passive starling exclusion, and the raise-and-lower pole compatibility that separates a managed colony from a gamble. The Grand Haven is the Purple Martin landlord's answer to quality over quantity — fewer rooms than the flagship models, but each one sized with the kind of intentionality that serious colony stewardship demands. Built from UV-stabilized copolymer plastic in the USA by Scenic Rivers Industries, fully compatible with The Elevator pulley system pole, and uniquely field-customizable with a paintable exterior that lets the landlord integrate this house into any landscape aesthetic they've built. This is a purple martin nesting box that arrives ready to perform — and ready to become exactly what you need it to be.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eScientific Engineering\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eStarling-Resistant Crescent Entrance Holes (SREH):\u003c\/strong\u003e Each compartment features a precision crescent-shaped opening measuring 3\"W x 1.125\"H — dimensioned to admit Purple Martins comfortably while physically preventing the larger body profile of European Starlings from gaining entry.
