Wind

As the flamingos make their journeys, they harness the wetness of the winds and skies. When they swim over the sea, heavier denser winds, thick with evaporated water from the sea’s surface buoy them up (roughly upto 200m from MSL). Here their wings flap to gain speed rather than stay afloat. To find these buoyant vapours they have to move out to sea, to where the continental shelf drops, and the mass of water and intensity of moisture  increase considerably.

As the monsoonal column rises, they rise, keeping company with jetstreams found at 9000m above mean sea level, utilizing the pressure differential between the heavy cumulonimbus clouds and the opposing jet stream to glide effortlessly. Flamingos across the world have been found to fly over 450 - 500kms in a single night without stops, yet at other times they make their way slowly, stopping at many feeding grounds, staying until the waters can support them

The flight of the flamingos creates coasts / thresholds of wetness, invisible to us, across the atmosphere. Their inhabitation of these coasts mark a separation as material and as imagined as the separation of land and sea.
