What is a group of penguins called?

There isn't a formally named group of penguins with a specific collective noun like "a murder of crows" or "a pride of lions." Penguin groups are generally described by their size and activity, such as a colony, a rookery, or a creche.

• Colony: This is the most common term and refers to a large group of penguins nesting and living together in a specific area. It can range from a few dozen to hundreds of thousands of birds.

• Rookery: Similar to a colony, but often implies a denser concentration of nests and a higher level of activity, particularly during breeding season.

• Creche: This refers specifically to a large group of penguin chicks huddled together for warmth and protection while their parents are at sea foraging for food.

So, while there's no single, charming collective noun for penguins like there is for some other animals, colony, rookery, and creche all accurately describe different types of penguin groups.
