The purple tree swallow is the largest swallow in North America. Males have shiny blue plumage with a purple sheen, females have duller gray.
The purple tree swallow differs from other swallows by its large size, purple sheen of plumage, and habit of living in colonies in artificial houses. It is useful for destroying numerous harmful insects.
