Today I joined the GOBG for an excursion on the south bank of Lake Geneva. After checking waders at La Coudrée, we heard a Common Cuckoo (Cuculus canorus) on our way to the car. The excursion leader/guide, Alexis, told me that the best chance to see a Common Cuckoo is to not look for it. :)

Our next stop was at the marsh area of the Domaine du Guidou. We walk to the newly built observatory, and after 2mn, a Common Cuckoo (Cuculus canorus) arrived! He stopped on a tree for 5 seconds, not enough time for me to fire. But then he took off and I just had the time to take this shot. So we did not really have time to admire it but I am still very happy to have actually seen this species for the first time.

As you can see on the picture, it is a Rufous morph Common Cuckoo (Cuculus canorus), which occurs occasionally in adult females but more often in juveniles. Being in April, I assume it is a female here.

The Common Cuckoo (Cuculus canorus) is probably the most famous parasitic species. Watching it flying today, I really appreciated how it mimics the sparrowhawk's flight and plumage. This evolution gives the female time to lay eggs parasitically. Nature is incredible!

Love Nature.
