These are not birds but more than sixty security cameras hovering over a street light in Shanghai’s Baoshan District. A very Big brother in China!
According to Hug China originally “only” 24 cameras were installed at the intersection, but an extra 36 were added, presumably because they didn’t have room for 37. For the record, the company who installed the cameras says that they’re there to check traffic flow!!
For the record, the cameras have been removed after the media in China started making noise about them.
