Bill Hudgins is a landlord. But he doesn't have to worry about his tenants not paying their rent each month.
They only come around for a few months each year, are purple and eat dragonflies, mosquitoes and other insects.
Hudgins, who has lived in Campbellsville since 1993, has nearly two dozen gourds and other "homes" for purple martin birds.
"They're all full," he said. "Last year, I hatched 185 birds."
He says the birds first came to his home in 1995, and the same birds have been coming back each spring since.
