The 'Colony Condo' Purple Martin House | Birds Choice Coates Original 2-Floor 8-Room Aluminum Habitat

The Experience

For the dedicated Purple Martin landlord, colony success begins with the right nesting box — and the Coates Original has been that nesting box since the early 1980s. This 8-room aluminum purple martin house set the standard for the industry at its introduction and has never relinquished it. Two floors of precision-engineered nesting compartments, a reflective roof engineered to attract scouts, and a full suite of colony management features combine to create the most consequential purchase a martin landlord can make. If you're serious about establishing or expanding a thriving purple martin colony, this is the structure your site has been waiting for.

Scientific Engineering

• Aluminum Construction: Aluminum is the material of choice for purple martin housing — cooler than plastic in peak summer temperatures, structurally superior to wood, and fully impervious to rot, warping, and weather degradation across decades of seasonal use.
• Reflective Roof: Engineered with a reflective surface that attracts Purple Martin scouts during spring arrival — a passive recruitment feature that increases first-season colony establishment rates.
• Ventilated Roof System: Roof ventilation maintains interior thermal regulation during peak nesting season, reducing heat stress on nestlings during critical development windows.
• Hinged Access Doors: Each room features a hinged door for direct nest monitoring, parasite management, and end-of-season cleanout — the baseline requirement for responsible colony stewardship.
• Porch Dividers: Integrated dividers prevent male porch domination, reducing inter-colony aggression and supporting stable multi-pair occupancy across both floors.
• Guard Rails: Perimeter guard rails protect fledglings from premature departure during the critical pre-fledge period.
• Door Plugs Included: Season-end door plugs allow the landlord to close and secure the house during the off-season, deterring sparrows, starlings, and other cavity-nesting competitors.
• Stainless Steel Hardware: All exterior fasteners are stainless steel, ensuring structural integrity through freeze-thaw cycles and prolonged outdoor exposure.

Boutique & Conservation Values

• Four-Decade Pedigree: The Coates Original wasn't designed by committee — it was designed by a martin landlord, refined through real-world colony management, and has remained the industry benchmark for over 40 years.
• Lightweight Pole-Mount Design: Despite its 8-room capacity, the all-aluminum construction keeps the assembled house lightweight enough for solo raising and lowering — a critical practical advantage during nest checks and seasonal setup.
• Heritage Manufacturing: Proudly Made in the USA.
