UFO grey alien spotted in Texas?

A UFO Grey Alien may have been photographed by a man in Texas. At least, it LOOKS like the classic alien shaped head seen in popular science fiction movies and TV shows. According to a video posted to YouTube, a man named Gary Richards was photographing the woods in Cibolo, Texas. After reviewing the photos later, he noticed a strange shape poking out between two trees. The shape appeared to be the classic face of what is called the Grey Alien, supposedly the cause of many UFO sightings around the world.  In order to verify his findings, Richards returned to the spot the next day, but was unable to see the same figure between the trees.

Does this mean Richards caught an alien on film? What happened to the strange figure the next day. If it was just a trick of light, wouldn't it have been seen on the following day?
