A communal nest is a place where multiple individuals from the same species gather to live, rest, and raise their offspring. There are different terms used to refer to this kind of nest, including a breeding colony, a communal roost, a communal lair, a hive, and a den. The term "breeding colony" usually refers to birds or mammals, while "communal roost" is commonly used for bats. "Hive" is typically associated with bees, while "den" is mostly used for wolves and other carnivorous mammals. Despite their different names, these synonyms all denote a shared living arrangement that allows for social interaction, protection, and mutual aid.
