A group of bunnies can be called by several different collective nouns, depending on the context. Here are some of the most common names for a group of rabbits:

• Colony: This term is typically used to refer to a group of wild rabbits living together, often in burrow systems known as warrens. It signifies the social structure and communal living aspect of rabbit behavior.

• Fluffle: This term is derived from the word fluffy, which describes the soft fur of rabbits. It can also refer to a group of young or baby rabbits, who are also called bunnies.

• Herd: This term is less commonly used, but it can be used to describe a group of rabbits. It is likely a carryover from terms used for other large groups of animals.

• Nest: In the context of baby rabbits, a "nest" refers to the group nestled together for warmth and protection. This term also refers to the physical location where a doe gives birth and raises her offspring.

• Litter: This term is commonly used to describe a group of rabbit kits. Babies are born in litters of around 5 rabbits on average.

• Warren: The term warren is sometimes used incorrectly to describe a group of rabbits. A warren is actually a network of underground burrows in which a group of rabbits live. Where a burrow is a home to a small family or nest of rabbits, a warren is home to the larger group to which that nest is a member.

• Husk: This term is commonly used to refer to a group of jackrabbits.

So, a group of bunnies can be called a colony, fluffle, herd, nest, litter, warren, or husk, depending on the context.
