Migrating birds stun Thai locals as they ripple through the air

Stunning footage shows a migration of thousands of birds above the jungle in central Thailand that appear to be constantly rippling through the air in a stream formation.

The huge flock of birds, believed to be swifts, were seen flying in a long line while heading to cooler regions.

The footage was captured in Nakhon Ratchasima in the region of Isan, on February 2.
