The common vampire bat, Desmodus rotundus, is renowned not only for its blood-feeding habits but also for its extraordinary roosting behaviors. These bats live in highly social colonies that can number from a few dozen to several hundred individuals, typically occupying dark, secluded places such as caves, abandoned mines, hollow trees, and even man-made structures. Within these roosts, vampire bats display remarkable social behaviors including communal grooming, vocal communication, and most notably, food sharing through regurgitation, which helps maintain group cohesion and ensures survival during times of food scarcity.
