Three fast-moving dots of light can be seen travelling close together in a video posted on YouTube by a KevinMC360.
The 'UFO squadron' shows the three lights in a triangular pattern spotted on May 26.
Cynics claim the cameraman has merely captured a flock of birds, but Kevin insists the sighting was genuine.
In the film, he follows a plane as a point of reference.
'For all you bird lovers out there you can call them geese, if you like, but I will only laugh at you,' he said.
The UFO video has already attracted more than 2,500 viewings.
He posted it a year after claiming to have filmed 'a group of spacecraft' over Oakland.
'I got them. There was a squadron of spacecraft,' he claimed in the video, which shows five lights in a V-formation. Source
