Animé par une passion de toujours pour la photographie et les animaux, cet auteur s'est lancé dans un voyage extraordinaire pour documenter les dix-sept espèces de manchots dans leurs habitats naturels à travers les océans du sud. Son dévouement s'est étendu au-delà de la capture d'images époustouflantes ; il a mené des recherches approfondies pour compiler la compréhension la plus complète de ces oiseaux captivants. Il en est résulté une œuvre remarquable qui allie magnifiquement les découvertes scientifiques les plus récentes à sa photographie évocatrice. L'auteur fait également découvrir la merveille des manchots aux jeunes lecteurs, en proposant des histoires captivantes enrichies par ses propres photographies de la faune.
