Discovery reports a swarm of UFOs over Las Vegas on 31 March 2012.

The UFO s movement is in vertical pattern.
They seemed to be in constant motion and hovering.
A video taken in Las Vegas shows what looks like white lights darting around the sky.
The person taking the video claims they’re alien.
A more likely explanation is they are bats and birds feeding on insects.
So what is it? Does this video really defy explanation? Or, as is the case with many UFO videos , is the explanation much more mundane?
A clue to the identity of the UFOs is their flight formation; they appear in a more or less vertical column. The video is very shaky, making it difficult to accurately judge the movement of the lights, but it’s clear that the unidentified flying objects are not hovering in a stationary position like many alleged UFOs. Instead, they’re in constant motion, like an airplane or animal would be.
Why is this important? Because mounted atop the 30-story pyramid is a 42.3 billion candlepower spotlight, the Luxor Sky Beam, which is the strongest beam of light in the world. The spotlight is a brilliant marketing tool that attracts millions of visitors each year — and also tons of moths and other flying insects. [Video of UFO Buzzing by Fighter Jets Bugs Believers ]
The UFOs are not bugs, but the bats and birds that have come to feed on them. These animals are large enough to be seen as bright dots from far away — especially birds with light-colored feathers.
This hypothesis is backed by video from another witness, one who was much closer to the mysterious glowing objects and their source. In this video, posted on March 22, it’s much clearer that the UFOs are medium-size flying animals that glow only when they dart through the Luxor spotlight.
