Either large flocks of birds are now wearing bicycle lights for added safety or something odd is happening in the US.
For the second time in 12 months, a large grouped ring of lights has been spotted hovering in the sky suggesting that not only is it a UFO, but one that has been around for some time.
The latest sighting was over the Estrella Mountains in Arizona where a driver was able to capture the collection of lights appearing in the distance.
These echo the images captured by numerous people back in August 2014 when a mass sighting of the lights over Houston in Texas caused videos and images to flood onto the web.
Some have suggested that they're a swarm of drones, or a formation of aircraft while others have gone for the far more interesting -- but categorically less likely -- suggestion that they're a formation of UFOs.
