The Purple Martin is a large swallow native to North America, known for its striking iridescent blue-purple plumage. These birds are social and often nest in colonies, favoring open areas near water. They primarily feed on insects, catching them in flight. During the breeding season, Purple Martins prefer to nest in man-made structures, such as birdhouses, which provide protection from predators. They are migratory birds, traveling to South America for the winter. Their presence is often welcomed by homeowners, as they help control insect populations.
