This is in fact an endless swarm of bats leaving Deer Cave (Borneo Island) to feed in the evening.

More than 4 millions wrinkled-lipped bats dwell high in the ceiling of the Deer Cave. Every evening, just before sunset, all the bats fly out of the cave to feed. The bats will spend all night hunting insects in the surrouding rain forest.

When flying out of the giant cave, this colony of about 3 million bats forms a swarm that looks like an endless undulating ribbon in the sky. The amazing show lasts for about 30 minutes every evening. Mesmerizing!
