Hi. I'm Docvox and I know nothing about birds. I enjoy woodworking and my wife has seen large multiple-occupant bird-houses and wants me to build a similar one. I think these may be purple martin houses, and we live in South-central NH, where, it appears those lovely critters are rare, indeed! I would like to build such a habitat for her, but, can I be certain there is a bird native to our habitat that would make it home? Is there a bird in our area that would be comfortable in a multiple-occupancy house?
