The cry of a penguin's baby seems monotonous, but it has many meanings. For example, when they are hungry, they will make high-frequency calls to attract their parents' attention. When baby penguins want to recognize their parents or tell them where they are, they will make low-frequency calls, which is a kind of help-seeking behavior. In addition, when they feel scared or confused, they will make a special cry, and close family members or partners can hear this change.

Penguins are birds with close family relations, and the communication between them is also the most wonderful. For example, penguin parents will come and feed their babies as soon as they hear their high-frequency cries. This kind of close friendship that helps each other is extremely valuable. In addition, when the baby penguin makes a special cry, family members can get more information through the change of intonation, which further increases the connection between families.

Penguins are precious protected animals. They are strictly controlled and protected. The cry of penguin babies is also part of species protection. When studying the behavior of penguins and their cubs, we can better understand their living habits and family relationships by collecting and comparing recorded calls, and in this way, we can protect and manage them more effectively. Therefore, the cry of penguin babies is also very important, especially in strengthening species protection.
