Is Gomantong Cave Bat and Swiftlet Exodus happening right now?

As of today, peak season now, through ~December 31. Earth Exhibit tracks the live conditions and flags it the moment it is on.

Gomantong Caves in Sabah host very large colonies of edible-nest swiftlets and insectivorous bats.

Each evening at dusk the birds and bats leave the cave in dense columns and spirals to forage, creating a dramatic wildlife spectacle visible from the cave entrance and nearby river.
