In the spring, he plants a garden on his vacation time. There's nothing more exciting to see the family of swallows nesting in the protagonist's very own garden. One of the children tells the other the amazing journey the swallows make all the way from South America to spend the summer in California during St. Joseph's Day to watch a family of swallows migrate far away from San Juan Capistrano to a peaceful island.
Juan sings "Las Golondrinas" before he plants his own garden for the swallows to nest at during his vacation time. On Saint Joseph's Day, the children sing "The Swallow Song" together while they join Juan in the garden. Juan returns to his adobe house and observes the migration of the swallows who nested in his garden on a rose bush that appears near Mission San Juan Capistrano.
