Those are amazing, that's one of the things I love about Instagram, you get to see pictures from all over the world from amazing photographers! I follow one guy that does awesome night photography all around AZ.
This guy below is a friend of mine and he gets some incredible wildlife shots. He's up along the seacoast at sunrise getting the perfect lighting conditions when the birds come out. He'll camp out in zero degree temps for 4-5 hours waiting for a snowy owl to take flight or swoop in for a kill on a vole.
Then he'll go looking for fox dens and get just jaw dropping shots of the kits. He has some on his feed and his personal website where he was sitting on a rock and one of the foxes came up to him within 10 ft

You don't just walk out here once and snap these shots. It's going out there 100's of times until you walk away with award winners like those on that link.
