Four Flamingos flying against backdrop of Andean Altiplano

with fabulous backdrop

I see it as two pairs - the infered depth of the background landscape adds a lot to this image and gives a true perspective of the distance these birds are travelling. The low angle light is also very pleasing.

Matthew, thanks very much for your thoughtful comments. It was a sunset with clouds coming in & the sun shining under them, giving a special lighting effect.Cheers, Sam.
