While filming the night sky over Oakland, CA last Thursday, a man who goes by KevinMC360 on YouTube captured something odd. He's calling it a "squadron" of UFOs.

In a video posted on YouTube and reported on by the site Ghost Theory, Kevin captures a group of objects flying in a tight "v" formation across the sky. The obvious answer to questions surrounding exactly what the objects are is that they're a group of planes. But in the video, Kevin shows some nearby jets as reference, and it differs from the tight-grouped objects. Still, it's possible the discrepancy could be explained away by distance.

Another possible explanation is that the objects are simply birds. But Kevin's not buying that.

"For all you bird lovers out there you can call them geese, if you like, but I will only laugh at you," he says in the video:

This isn't the first time Kevin has captured UFOs. One year ago he captured two other groups of mysterious lights over Oakland, and again compared them to nearby jets:

What do you think? Birds, planes, or maybe even extraterrestrials?
