Did you know that every fourth stork in the world is Polish? Attesting to Poland's numerous wetlands and free-flowing rivers, the storks choose Poland over every other European country to build their nests. A favorite nesting place for storks is at the tops of the poles that convey electricity. When storks leave for the winter, the Polish power company builds a platform and sets the nests back on the platform to make sure the young storks don't lose their lives on power lines when they first leave the nests. Roman Guziak, Vice President of the Polish environmental group "pro Natura," blames intensified agriculture for driving the storks away from other European countries. Denmark boasted of 10,000 pairs of storks in 1900; now there are only six pairs in the whole of Denmark.
