A tough shot for a camera where there are

When the bats come out they fly up from below
in a counter-clockwise funnel like pattern.

The fluttering sound they make gets louder

like they are going to fly right into your
face.

Bats are a valuable asset to the local farmers,
orchards and vineyards. This swarm will consume
over 18 tons of crop insects a night.
