Corynorhinus mexicanus

Mexican Big-eared Bat

Order: Chiroptera
Family: Vespertilionidae


Conservation Status: Near Threatened.

Mexican Big-eared Bats fold back their ears, which are exceptionally large - and pleated - when they roost. They roost apart from each other, not packed together in clusters, in caves or mine tunnels, clinging to vertical surfaces with their toes and the thumb on each wing and with their tail curled forward under the body. Some have been found hibernating in deep caves. Females give birth to a single offspring, not twins, in the spring. Mexican Big-eared Bats have been found in small numbers in dry lowland forests and higher-elevation pine-oak forests. They probably eat small flying insects.

Range: Head and Body: 38-62 mm; Tail: 40-50 mm

Range: 5-10 g
