Crèche (zoology)

In zoology, a crèche (from a French term for childcare) is an animal behaviour where offspring are cared for as a group by multiple females. Many species such as common eiders, lions, and penguins form crèches and exhibit group behaviours.

Crèches can serve different functions and purposes depending on the species and the environment. For example, some crèches may aid in defence while other crèches may aid in feeding and protection from harsh weather conditions. This form of group living has evolved to become advantageous to the species. Studies have shown that by participating in group living, species will increase their inclusive fitness since their young will be in a better condition to reproduce and carry on the line of descendants in the species.
