Pampas deers (Ozotocerus bezoarticus, veado-do-campo) are commonly seen around here. They inhabit the grasslands and are a very important indicator of habitat health. Their main predator are the pumas (Puma concolor, onça-parda). When alarmed they stamp their hooves, lift their white tails and move away in a particular trot and with a silent whistle depositing odor.
Due to high genetic variability pampas deers are one of the most polymorphic mammals in South America. This suggests that the numbers of deers were vast in the recent past. The Pantanal is one of the last strongholds of this species.
