On the occasion of the WMBD on 12-13 May 2007 the Dortmund Zoo highlights the threats for three of its bird species caused by climate change. The Zoo will publish a press release with information concerning migratory birds. In this particular case, the White Stork, the Crane, and the Turtledove serve to represent the many other migratory birds facing the loss of their habitats and changes to their migration patterns, which endanger their survival.
