The story takes place in RHS Garden Wisley, where two exhausted robins, Connie and Gerry, are finally resting after raising their own chicks. Their peace is interrupted when a large, unknown bird crash-lands into their tree. The bird, confused and upside down, turns out to be a young heron they call “Big Bird,” who has been blown far from his nest by strong winds. Realising Big Bird is lost and alone, Connie and Gerry try to help. Gerry searches for the nest but cannot find it, and Big Bird becomes distressed and hungry. Because of his enormous appetite, the robins recruit help from their friends and children—including Squirrel, Caterpillar, Snail, and other young birds—to gather food. Despite everyone’s efforts, Big Bird is constantly hungry, and feeding him becomes an exhausting, ongoing task. entually, the group learns that Big Bird’s nest has been destroyed and abandoned. With no family to return to, the animals decide to continue caring for him. Over the course of about a month, they work tirelessly to feed and raise him until he grows strong enough to fly. As Big Bird prepares to leave, he feels sad about losing his original parents and having nowhere to belong. Connie and Gerry offer to adopt him, giving him a new family. Comforted and grateful, Big Bird accepts. Soon after, he takes flight, promising he can always return to visit his new family. The story ends with Connie and Gerry finally resting again—only to hear another crashing sound, humorously suggesting their hard work may not be over.
