Fun Fact

Pallid bats can eat up to half of their body weight in one day.


Pallid bats use a lot of different habitats, including grasslands, shrublands, woodlands, and forests. They are most commonly found in open, arid habitats with rocky outcrops – or structures that mimic rocky outcrops, such as bridges, hollow trees, or mines – for roosting (resting).




Woodlands and forests

Disturbance and Stressors

Human development such as urban growth and transportation development or maintenance, loss of habitat and fragmentation, and noise pollution, all contribute to the decline in pallid bats.
