French Pyrenees - Vallée de Héas


Late last year when I had recorded and photographed the complete list of UK mainland butterflies the elation I felt turned to despair - no more butterflies to chase. Over the winter I decided that if I wanted to find more then I would have to venture into Europe. I have never been on a tour as I felt that I would often rather stay and obtain better photographs when other members of the group would rather press on to pastures new.
However, I decided to give it a go and after much searching on the internet opted for a trip to the French Pyrenees with Naturetrek.  So yesterday found me journeying via Stansted to Lourdes, by the time we disembarked the aircraft our group of six had loosely formed and like all good naturalists "ticking" had started. Mowing of grass strips around the runway had attracted a dozen Black Kites whilst overhead Swifts screamed in welcome.

Exiting the baggage collection we were greeted by Jason, our group leader for the week. Our base was to be at La Breche de Roland hotel in Gedre but we managed a stop in Luz-Saint-Sauveur for picnic supplies. A short walk around the town gave sightings of Crag Martins, Swifts and what was to become the ubiquitous bird of the trip - the Black Redstart. Swiftly onward to the hotel which was situated amidst stunning surroundings - by this time any trepidation had long disappeared and I realised that I was going to enjoy the week.
It had been a long day, so, after a pre-dinner aperitif we dined and then I retired early. Next morning we assembled in the car park ready for our first day in the Pyrenees. In the meadow adjacent to the hotel a manure heap was providing a feast for a White Wagtail family, Black Redstarts, sundry House Sparrows and a drop dead gorgeous male Red-backed Shrike who was obviously feeding a family. Then an exclamation of disbelief as Jason spotted a Lammergeier - a long way up but unmistakeable, What a start!

  Day 2  - Vallée de Héas, Lac des Gloriettes and the Cirque d'Estaubé


We began at a convenient pull off on the D922 going up the valley, the sun was shining and a promised temperature of 27 degrees augured well for a butterfly hunt. It was good to start with some familiar specimens, Large Skipper, Essex Skipper and Dark Green Fritillary, nice to get the eye in, so to speak. Then the pulse quickened, A Southern White Admiral drifted past and I gave chase up the road, it paused just long enough for a hasty record shot and disappeared into the roadside trees.

Next stop was just a short way up the road at Pont de Souarrouy, plenty of butterflies on the wing but Swallowtail, Black-veined White, Wood White, Large Ringlet, Piedmont Ringlet and Pearly Heath were notable additions.

 The orange colouring of the hind wings of the Black-veined White threw me until I noticed a stand of Martagon or Turk's Cap Lilies close by. Lily pollen sticks to anything that nectars nearby.

Plenty of day flying moths - Companion Burnet and Black-veined Moth on the wing.

 Another short trip further up the road to where a footbridge crosses the Gave de Héas, the flowers of the uncut roadside verges providing a host of nectar sources for a wide range of butterflies. Notables were Clouded Apollo, Heath and False Heath Fritillaries, which I found most confusing, and Lesser Marbled Fritillary.

Finally for this stop, a pair of friendly BvWs without added colour.

 We were dropped off and allowed to walk the last half kilometre to the car park at the barrage, where we had a fine picnic lunch in hot sunshine at an altitude of 1716 metres or 5630 feet in real money.

After lunch we ventured across the barrage to search for more species. Highlights for me were Mountain Ringlet, Piedmont Ringlet, Geranium Argus and Olive Skipper. In the heat the butterflies were hyperactive and not given to posing for photographs. So I was happy that Jason netted a few species and displayed them to the group - of course on release they vanished as fast as they could.

Plenty of  plants to be found including  Burnt Tip Orchid, Neotinea ustulata,





Maiden Pink, Dianthus deltoides




Dianthus monspessulanus




Sempervivum species



 The scenery was simply stunning - unfortunately my photographs don't do the Pyrenees justice.




I was intrigued as to why alpine lakes are blue-green. The answer is apparently to do with the interaction of limestone "rock flour" and the wavelength of light - very interesting but far too complicated for a blog!

All the searching on the ground meant that inevitably birds were missed but notables were Bearded and Griffon Vultures, Alpine and Red-billed Chough and Serin.

 All in all a brilliant first day which concluded with "une bouteille de Bigourd'ale Blonde" and a fine meal.

To be continued.
