Why is penguin live in flocks sticking close to each other?

Penguins live in flocks and stick close to each other primarily for protection against predators and harsh environmental conditions. By huddling together, they can conserve warmth in cold climates, reducing heat loss. Additionally, social interactions within the flock help with foraging, mating, and raising chicks, enhancing their survival and reproductive success. This communal behavior is essential for their overall well-being in the challenging habitats they inhabit.
