Back to the cradle

“Sleep, oh sleep, my dearest boy./I will cradle you. I will guard you”

– Henrik Ibsen

Visiting Llobregat Delta always brings me a lot of good memories. The field where I saw a marsh sandpiper last year, the fields where I found a Rose-colored starling, the reeds where I ringed an Icterine warbler, an Iberian chiffchaff, another Iberian chiffchaff, some Moustached… The day of the 7 White-winged terns, the day of the Cream-colored courser, followed by the day of the Broad-billed sandpiper. All of that, concentrated in the Prat de Llobregat area, what means memories can be multiplied by 2 if we take the whole Delta.

Back in Barcelona, to visit the Llobregat was one of the first things I had to do. There was a Blue-winged teal but I didn’t care actually… I wanted just to be there and see what the Delta could offer to me. July is not the best season to enjoy migration but only by seeing the local species, I remembered what “diversity” means. Since I’ve returned to the continent and seen even the most common species, I realized how hard it must be to colonize an archipelago such as the Canaries.

Both dragonflies and butterflies are at their maximum, and I was able to see the rare (the UICN declared it “Vulnerable”) Mediterranean skipper Gegenes nostradamus. It’s neither beautiful nor colorful, but it’s enigmatic and hard to see… that’s enough.

I didn’t have too much time to look for dragonflies, but I saw 7 species at a glance. Blue-tailed damselflies Ischnura elegans were mating while keeping an eye on the Black-tailed skimmers Orthetrum cancellatum. I looked at that during only 10 minutes, but I saw at least 5 catches of damselflies by the powerful skimmers. The Violet dropwings Trithemis annulata seemed to be quieter, maybe enjoying the show played by others’ frenetic life.

And what about birds? I didn’t see the teal. I saw a nice female in April while I’ve not seen a Black-winged stilt since long time ago. However, the best was a singing male Savi’s warbler Locustella luscinioides at Calaixos de Depuració de Ca l’Arana, an irregular breeder at Llobregat Delta. I don’t know if we are already in the dispersive period, but the habitat is suitable for the species and the bird was singing.
