As there were many discussions about how soaring birds help us find thermals, this may be of interest to at least some of us: storks have arrived today, after a long trip from Africa, to Przygodzice, just south of Ostrow Wielkopolski in Poland, the site of WGC 2018. You can watch them live improve their nest, hatch the eggs, teach the new generation to fly, between now and mid-August, when the new enlarged family will set off to Africa for the warmer climate:

Enjoy! When you fly in Leszno, Ostrow or anywhere in Central Europe for that matter, please remember that they are kind of timid so don't get too close. Also, frankly, they are, IMHO, no so good in centering thermals as some birds of prey.
