Purple Martin

Progne subis - Locally common where proper multi-celled nesting boxes or gourds are provided. No other Northern American swallow is dark all over. Females, young, and first-year males are light bellied and could be confused with smaller swallows. Watch for purple iridescence on head and top of wings. Note the broad wings and more soaring flight of martins. Song and calls are a distinctive, low-pitched, liquid, rolling twitter.
