These amazing pictures, taken from a dilapidated World War Two aeroplane, show a true bird's-eye-view of enormous flocks migrating hundreds of miles across the hemispheres.
The incredible project is the work of German photographer Florian Schulz who has travelled across the globe to document some of nature's greatest events.
Using a two-seater Piper Cub aircraft, Florian, 35, was able to soar to over 1000ft thousand feet up and capture birds on the wing in Alaska, Canada and Mexico. The plane may be ancient but it is nimble and it allowed dedicated Florian to land almost anywhere. He slept in a bivouac and his pilot slept in the plane.
He even dived underwater braving -1.5 Celsius temperatures to capture Thick Billed Murre's swimming, before snapping them from above in his plane.
Other species captured on film in his trip included sandpipers in Prince William Sound, Alaska. Eight million of the birds pass through the area over a week as they migrate from Mexico to the Arctic Tundra.
He also pictured frigate birds in the Yucatan Peninsula, Mexico, and American Avocets wading in the afternoon sun on the Colorada River Delta, Mexico. after going to Mexico and seeing how some birds raise their young in freezing temperatures.
Florian said: 'It's a good example to show the interconnectedness to the natural world. They move with the seasons depending on what they need to do like mating, eating and birthing.
'It's fascinating how the same birds adapt from the cold of the high Arctic to the heat of the deserts in the south.'
