What is the collective name for a group of penguins?
There is no generally accepted collective noun for penguins. A large breeding group is commonly refered to as a “colony” of penguins. The place where they breed is variously known as a “Rookery” or “Penguinery”; both these terms are also sometimes used to describe a large group of penguins on the land. However, penguins usually spend most of their time in the sea; a group floating on the surface is sometimes called a “raft” of penguins.
