How do penguins find their chicks in large colonies?

Penguins find their chicks in large colonies by recognising their unique calls. Despite the noisy environment, each chick and parent has a distinct vocalisation, allowing them to locate each other among thousands of birds. Penguins also rely on memory and visual landmarks within the colony. This precise recognition is crucial for feeding and bonding, ensuring the chick’s survival. The ability to identify specific calls demonstrates the importance of sound in penguin communication.
