Birds Choice Purple Martin House, Premium Aluminum 12-Room 3-Floor — Starling-Resistant Holes & Ventilated Roof

Birds Choice Premium Aluminum Purple Martin House is a three-story, 12-room metal birdhouse engineered with starling-resistant entrance holes, ventilation, and easy-clean hinged panels to support a healthy Purple Martin colony.

This American-made Purple Martin house combines lightweight all-aluminum construction with predator-aware design so landlords can attract and protect colonies season after season. Precision-cut starling-resistant entrance holes (SREH) let martins enter while blocking aggressive starlings; the house also includes porch dividers, guard rails, and a reflective roof to enhance occupancy. Built in Wisconsin and supplied unassembled, it balances long-term weather resistance with manageable maintenance.

How does this house keep European starlings out while letting Purple Martins in?

The house uses crescent-shaped Starling Resistant Entrance Holes cut to an exact height that prevents starlings from squeezing through but accepts Purple Martins safely. Independent tests show high effectiveness at reducing starling invasions so nests face less competition and disturbance.

• Exact-height SREH design tailored for Purple Martin body size
• Crescent openings limit aggressive invaders without harming martins
• Reduced nest takeover increases breeding stability

What features make this birdhouse durable and low-maintenance?

Constructed primarily from aluminum with stainless steel hardware, the house resists rust and stands up to wind, rain, and sun better than many nonmetal options. Hinged doors and an all-aluminum base plate let you inspect and clean nesting compartments quickly, keeping colonies healthy with minimal effort.

• Weather-resistant aluminum walls and roof for long service life
• Hinged cleanout doors for fast, safe inspections
• Stainless fasteners and a solid base plate for stability

How does the layout support successful nesting and chick safety?

The three-level, 12-room layout gives each pair a 6" x 6" nest compartment with porch dividers to limit territorial disputes and ceiling plates to prevent brood disturbance. Guard rails and a top perch reduce fall risk for nestlings and provide landing help for incoming martins.

• Twelve 6" x 6" compartments for evenly spaced nesting territories
• Porch dividers discourage dominant males from monopolizing multiple rooms
• Guard rails and perch features protect young birds

Does the house help with temperature control and attracting martins?

A ventilated roof encourages airflow to keep interiors cooler on warm days, and reflective roof material helps make the structure more visible to migrating martins. Together these features create a more comfortable, attractive nesting site without artificial heating or cooling.

• Roof vents for improved airflow and heat reduction
• Reflective finish increases visibility to migrating birds
• Lightweight build simplifies pole raising and lowering
