The Purple Martin North America's largest swallow. They have a lot of speed and agility in flight, and when approaching their housing, will dive from the sky with their wings tucked at great speeds.
It is the only bird totally dependent on humans for nest sites.
Their breeding habitat is open areas across eastern North America, and also some locations on the west coast from British Columbia to Mexico. This species typically breeds in colonies located in close proximity to human housing. The eastern nominate race nests exclusively in man-made bird houses, of which about a million are provided.
