Col de Bretolet and Col de Cou
This page is dedicated to our insect migration research project carried out at one of Europe’s most famous migration hotspots, the alpine passes Col de Bretolet and Col de Cou in the Swiss Alps.
Check out our Facebook album and follow us on twitter for regular updates.
We are grateful to the Swiss Ornithological Institute for allowing us to work at the bird ringing site on the Col de Bretolet, and the municipality of Champéry for allowing us to use the former border patrol house at Col de Cou as our field station.
