Colorful creatures: Purple martins are known for their distinctive deep purple and blue feathers. Many people find their singing intoxicating.
Aerial artists: The birds are also famous for their speed and agility in the air. They do almost everything from mate to eat while in flight.
Diet: They're also loved for their food choices because they feast primarily on insects.
It takes a village: While a mother and father typically raise the young, purple martin families often live in groups or colonies.
Roosts: The birds will gather in large roosts weeks before their migration back to South America. Lewisville officials estimate that a roost there usually includes 50,000 birds, though some estimate past roosts at 100,000 birds.
