As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Scientists can predict which storks will migrate to Africa in autumn and which will remain in Europe

For little Louis, it is the most exciting day of his life: just six or seven weeks ago, the young stork came into the world on a birch tree in Radolfzell on Lake Constance. Up to this day in June 2014, he has only known his parents and three siblings. But suddenly strange beings have appeared at the nest and are holding the four small white storks captive. They are Andrea Flack and Wolfgang Fiedler of the Max Planck Institute for Ornithology and the University of Konstanz. In the coming years, the scientists will learn from Louis and other young storks that, on their migrations south, storks follow other storks who are particularly good at exploiting thermals, allowing them to flap their wings as little as possible as they fly. The efficient fliers migrate to West Africa, while the others spend the winter in southern Europe. From their data, the researchers can tell which storks will fly where just ten minutes after the birds take off.
