What is a group of penguins called?

A group of penguins on land is often referred to as a waddle. This term describes their somewhat clumsy, side-to-side gait as they move across the terrain. The term "waddle" is most commonly used when the penguins are moving as a group.

When penguins are in the water, a group of them is called a raft. It's a fitting term as they often huddle together for warmth and safety while at sea. A raft can vary greatly in size, from a few individuals to a very large gathering.

There is also a less frequently used term, a rookery, which refers specifically to a breeding colony of penguins. A rookery can consist of hundreds or even thousands of breeding pairs.

Here's a summary of the terms:

• On Land: A Waddle
• In the Water: A Raft
• Breeding Colony: A Rookery
