Peter's Ghost-faced Bat

Peter's Ghost-faced Bat

Peter's ghost-faced bat has reddish brown to dark brown fur, a short nose, large ears and distintive folds of skin on its face. This bat is found in warm habitats with a range from southern Texas and Arizona in the US through Mexico, Central and South America. They roost in large groups within caves and mines at lower elevations. Peter's ghost-faced bat does not migrate or hibernate. Moths are one of their common foods. Mothers give birth to one pup per year and the lifespan of this bat is estimated to be around 20 years in the wild.
