What is this bellow? 

Looks like a dying thunderstorm to me.,.

Happen to have a loop and know what time of day it was? Most likely either a dying thunderstorm that went splat and created the outflow that stirred up bugs and other animals (birds, bats,etc) or it could have been the end of daytime scenario with similar animals and bugs that happened to get caught in concentration. 

 

Hard to tell though without a loop.
