Hi, 

Today, the swallows were migrating very actively. We controlled a Trush Nightingale that was ringed 10 days ago. This species is quite a rarety in France so we were very happy to see one.
The sound recording of the night revealed some Tree Pipit migrating and a Golden Plover.

We are observed a caterpillar of Cerura vinula, the Puss Moth. This species is distinctive appearance and impressive caterpillar. The adults are fluffy and pale grey, while the larvae are bright green with a forked tail and striking defensive behaviour. When threatened, it raises its head to reveal a reddish “face” and waves its tail — and can even squirt formic acid at predators. It is typically associated with willow and aspen, and is widespread across Europe, including here in Norway.
