If you want to attract bluebirds to your yard, Carter recommends buying a special bluebird house for them, with the right sized opening. "It's best to put the house up in February, because then the bluebirds have time to shop around for a home, but you probably still have time to attract some this season," she says.
Add water and a feeding station. "They especially love mealworms," Carter says. "The birds will see, 'What a great neighborhood, it's got food and it's safe,' and they'll move in."
