Heath Outdoor Products Purple Martin House M12SR — 12-Room Cedar Starling-Resistant with Removable Roof

The Heath Outdoor Products M12SR is a 12-room, starling-resistant Purple Martin house built from durable cedar with removable roof access, railings, and perches for safe colony nesting.

Engineered for Purple Martins that thrive in communal housing, the M12SR brings a traditional wooden colony structure with modern, predator-aware details. Constructed of naturally weather-resistant cedar, this martin house balances longevity with lightweight handling for seasonal maintenance. Starling-resistant openings and internal railings help protect young birds while the removable roof and included hardware make checks and cleanouts straightforward.

How does the M12SR keep Starlings out while letting Purple Martins nest?

The house uses openings sized specifically to admit Purple Martins but exclude larger, more aggressive birds like starlings. That passive design avoids extra gadgets and lets the martins colonize naturally while minimizing conflicts.

• Each of the 12 rooms has a purpose-built entrance diameter to deter starlings
• Wooden construction allows precise, factory-cut openings that don’t deform over time
• No add-on starling traps required when properly installed and monitored

What features make the M12SR easy to maintain and inspect?

The roof removes completely, providing full access to all nest chambers for cleaning, egg checks, and repairs without disassembling the whole structure. Durable materials and included mounting hardware reduce the number of replacement parts you’ll need season to season.

• Removable roof for unobstructed interior access
• Hardware included for secure assembly and mounting preparation
• Cedar exterior resists rot and reduces frequency of major maintenance

How does the house promote safety for nestlings and returning adults?

Inside each compartment, short railings give fledglings secure footholds as they learn to leave the nest, and the top perch provides a staging spot for arriving and departing birds. The cedar construction is solid yet smooth, reducing accidental injuries to delicate feet and wings.

• Railings in each room protect young birds during fledging
• Extra top perch gives adults a landing point and lookout
• Natural cedar surfaces minimize splinters and weather wear

Can I mount this on my existing pole and where should it go?

The M12SR is ready to be mounted on a separate pole (pole sold separately); position it in an open area away from dense trees and close to flying space for martins. Proper height and a clear landing approach improve colony occupancy and reduce predation risk.

• Mount on a sturdy pole sold separately—follow recommended martin-height guidelines
• Place in open flyways, 30–100 feet from dense cover or heavy tree lines
• Ensure easy access for seasonal checks and cleaning with the removable roof

Who is this for? The Heath M12SR is ideal for backyard naturalists, bird-conservation hobbyists, and community green-space stewards who want a durable, low-maintenance Purple Martin colony house. It suits anyone seeking a quality wooden nest structure that prioritizes starling exclusion, safe fledging, and straightforward upkeep. Because Heath partners with Next Step of West Michigan, this purchase also supports local job-training initiatives—so you bring martins closer while supporting community employment.
