The subspecies L. m. bourdilloni is distributed in Southwest India. The subspecies L. m. macrotis is distributed in more than eleven islands of Philippines. The subspecies L. m. cerviniceps is distributed in Northeast India, Bangladesh, South China and southeast Asia. The subspecies L. m. jacobsoni occurs in Simeulue Island located off Northwest Sumatra in Indonesia.Movement and migration patterns
