Wryneck

Here is a pictures from a Wryneck

Wryneck (Jynx torquilla) populations are declining in whole Europe. The reasons for this decline are not fully understood and it is therefore difficult to propose sound conservation actions. We study the dynamics of a population in the Valais as well as the habitat selection in different areas.
