is this crane doing?
drinking water is important for crane survival. This juvenile
crane is drinking from a water guzzler in the Chass pen. The guzzler
is filled using gravity. Water is pumped into elevated barrels
near the blind. A hose connects the barrel to the guzzler. The
pressure from water in the barrel forces water through the hose
and into the guzzler for the juveniles. More below picture.
The water in and around the pen usually has an average salinity of 17 parts per thousand, too salty to drink. (A liter of water contains about 17 grams of dissolved salts.) that's too salty for cranes to drink. Salinity at the pen site is affected by such things as rainfall and tides. Giving fresh water to the young cranes means they don't have to fly far inland to find fresh water when they are thirsty. Their body fuel is saved to get them ready for spring migration.
