(Video) What is on the video? The angels, aliens, demons (jinns)?

On location Boa Vista in Brazilum, amateur cameraman filmed the strange objects in the air.
It was originally thought that captures an unusual type of birds. But when zoomed to have a better insight, he noticed that they were two strange winged creatures that resemble what people may call angels (or demons - jinns).
In any case, this is something the same unusual.
Watch the video and judge for yourself.
