Manou the Swift (2019)

Manou is a young swift who grows up believing he is a seagull like his parents. He strives to swim, fish and fly like them but seems not very gifted. At Summer race he discovers why. To his great shock he finds out he was adopted as an offspring of the much-hated swifts. His family still stands by him, claiming he is a bird like them. When he gets banished from home, he runs away, meets birds of his own species and finds out who he really is. When both seagulls and swifts face a dangerous threat, Manou must rise to save the day.
