Alien Head or what????

Ok, this came from a remote piece of land. These are very expensive solar powered cameras. They utilize high power motion sensors. I have no idea what that is that appears to the left of the video. Anyone who wants the original to embed or who can upload and check this out please do.

To me it looks like an alien head materializing and dematerializing very quickly. This is real time footage and no way tampered with. I am just looking for help here as some of you are good at analyzing these kind of things.

Here is the video.
