Some observations on Notopteris macdonaldi (Chiroptera: Pteropodidae).

Abstract

Some field experiments on the orientation of the cave roosting Notopteris macdonaldi showed that these flying foxes were unable to avoid obstacles in complete darkness or when blindfolded, but were able to do so in very dim light. No audible or ultrasonic sounds that could be used in ecolocation were detected during their flight. Some observations are reported on body temperature and reproduction.
