User ERN D (@erndawg0420) shares stunning photos of enormous swarms of birds. Birds blot out the sun in his photos, filling the sky by the thousands leaving barely a patch of blue between their flapping feathers. These are potentially the great migrations of the changing season, it is hard to say for sure, but what can be said is that ERN D has got some stunning natural photography on his PicsArt page. Check out some of his very best shots below!
