A few years ago I was sharing a thermal with three storks at 1800 m
and it seemed that one of them was very young and had not mastered its
thermaling technique quite yet. It would make sudden corrections and
flap a few times while the other two calmly circled and waited for it
to catch up. When they got together they took off in tight formation.
I was headed in about the same direction so I was able to watch them
for several miles and I was amazed by their glide speed which appeared
to be close to 80 km/h. Truly incredible birds.. I don´t know if they
soar for fun but it looked like they were having a great time.
