Purple Martins are the only North American songbird that now depends entirely on humans for nesting (with some groups in the southwest still nesting in natural cavities). Learn where they live, what habitat they need, how to set up proper housing, and why monitoring for predators and invasive species is essential to helping this remarkable bird survive and thrive.
