Here ist a picture from a Hoopoe

The Hoopoe is one of the most endangered bird species of Central Europe. In Switzerland it lives mostly on the plain of the Upper Rhone valley, in the Valais Alps. As the Valais population was steadily declining, the Swiss ornithological institute launched an evidence-based conservation programme in 1998. This led to a rapid recovery of the population within a few years. The Valais Hoopoe population has become one of our major research models. We have conducted research on habitat selection, diet, reproductive ecology, eco-toxicology, migration and population dynamics, and continue to work on this fascinating bird. Our results provide essential information for species preservation in Central European agroecosystems.
