Vagrants are individual birds that get lost during migration. Billions of birds migrate each year for better wintering, nesting, and breeding locations. According to the Hong Kong Bird Watching Society records, thirty-nine vagrants deviate from their migratory routes or destinations due to climate change and environmental conditions, and become accidental tourists or residents in Hong Kong. In the Vagrants series, Lui records the evidence of the thirty-nine vagrants’ existence in Hong Kong.
