While searching more on the storks legend and sayings I discovered one I did not know. Mainly that long time ago where there were too many reptiles and amphibians in the world God put them all into the shawl and ask one man to throw them into the ocean but without opening it. But staying on the seaside the curious man could not help and opened it letting them escape. God being angry changed him into stork and ordered to clean the world as a punishment. And this is what storks are doing since then.
