The Champfromier-Giron forest is home to one of the High-Jura’s most iconic birds: the western capercaillie. A sign of the diversity of high forests, this bird - also known as the wood grouse - is omnipresent here. The male favours old forests, while the female, who moves around more, prefers to spend her winters in bushy areas and raise her young in clearings. This bird is particularly sensitive to disturbances in the winter and spring. There isn’t much chance of seeing one, but if you do, be sure to make the most of this extraordinary moment and stay quiet and on the waymarked paths.
