Purple martins winter in Brazil, returning north in early spring. Adult martins scouts come first, looking for suitable housing for the colony (which arrives a few weeks later). Be ready to welcome them by installing this starter house on your property. We offer 1-story, 2-story, and 4-story styles. Plus, an add on room if needed. This house has six apartments for these communal birds. Easy to clean, assembly required. Door stops and rails included. Mounts easily with our (QBP15) Telescoping Purple Martin House pole (see below) sold separately.
