The collective nouns most often used for beavers are “colony” and “family”. A colony is a group of beavers that share the same habitat, whereas a family is a group of related beavers that live together. Beavers can also be described as a lodge, meaning a group that shares a single home.
These collective nouns for beavers grow out of how the animals actually live. Because beavers gather in large groups and build close family ties, the words “colony” and “family” fit them naturally. “Lodge” comes straight from the homes beavers construct out of sticks and mud.
