 Their burrows were described in 1999 by a source that did not distinguish between "B. hamorii" and "B. smithi".The deep burrows keep them protected from predators, such as the white-nosed coati, and enable them to ambush passing prey.The females spend the majority of their lives in their burrows, which are typically located in, or not far from, vegetation, and consist of a single entrance with a tunnel leading to one or two chambers.
