Four S\u0026amp;K Bo Plus Combo Purple Martin Gourds in a single pack, each engineered with the kind of specification list that serious landlords recognize immediately as the difference between functional housing and purpose-built colony infrastructure. Attachable porches. Closeable entry covers. A 4\" access port with a protective cap. Crescent SREH entrances that physically exclude European Starlings. One-piece construction with a dark, weather-resistant interior that creates the cool, sheltered nesting environment Purple Martins actively seek. And textured white plastic that keeps the interior temperature regulated even during peak summer heat. Built in the USA by S\u0026amp;K Manufacturing — the same team behind some of the most trusted martin housing on the market — The Penthouse is the gourd for the landlord who refuses to compromise on what goes up on their rack.\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=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCrescent Starling-Resistant Entrance Holes (SREH):\u003c\/strong\u003e Each gourd features a precision crescent-shaped opening measuring 2.25\"W x 1.25\"H — physically excluding European Starlings while admitting Purple Martins without restriction.
