The greater bonneted bat is the largest molossid bat in North America. Its long ears meet above the head, and it launches from cliffs before hunting insects at night.
Its large ears join across the top of the skull and project beyond the snout. Its wings are long and narrow; the back is dark gray-brown and the underside paler.
It flies at night to catch insects. It roosts in high places such as cliffs and rock crevices, needing open space below to launch; it cannot take off from the ground.
