UFOs Caught Swarming Around Volcano Moments Before It Erupts (Video)

The video below shows UFOs moving around the Colima Volcano In Mexico.

They appear in frame right before, during and after the main explosion. They also move at an extremely fast pace.

According to the user who uploaded the video:

Lets be clear here. They are are not birds , drones or any other technology currently known to man. They are being seen more and more around volcanos and they appear and vanish with lighting speeds. They may be able to evade the unaided human eye, but a closer examination of slowed footage tells the story. These things are everywhere.

What do you think the object seen in the video are? Man made, a video glitch, or something else? Comment below.
