   We went to Donegal for a week in July and on announcing our intended destination we received many ominous warnings about the weather. Sure enough we left Dublin in baking sunshine with the temperature in the mid-20s and by the time we reached Donegal it was raining heavily. But next day the sun was out and it was glorious as we drove north beside a sparkling sea stopping at a viewing area overlooking a lovely little bay where Lucy spotted a Porpoise with a calf. We were heading to Slieve League. I’d visited the famous cliffs back in 1995 but there was nothing then like the throngs of visitors that were there this time. It has two car parks, one at the base of the winding road the other at the top near the cliffs, full of cars, camper vans and fast food stalls. Taking advantage of
the crowds or, more specifically, the uneaten food they leave behind were a pair of ravens, hopping around a few feet away and occasionally perching on direction signs. Further up the coast at Glencolumcill we got our only sighting of Chough when a little flock flew over.
  One place in Donegal we specifically wanted to visit was a nature reserve at a beach at Sheskinmore which earlier this year featured in a wonderful wildlife documentary about the Wild Atlantic Way, in a sequence where a nesting Skylark was filmed bringing food to its young. The cameraman had told us it was a lovely area with the beach backing onto dunes covered with wildflowers. As we wound along the path, lined with Common Spotted and Pyramidal Orchids, towards the beach a large raptor flew over, though only getting a glimpse, it was almost certainly a female Marsh Harrier.

  The beach was as lovely as we anticipated; miles of white sand with only a handful of people on a warm summer’s day and as we rounded one headland we saw a big raft of ducks cruising through the surf. They were Eider, the largest of our duck species, beautiful birds with their distinctive sloping forehead who breed on many of the uninhabited islands off the Donegal coast. Further along Ringed Plover rushed around the beach probably having nested nearby.

    We stayed in Dunfanaghy and went on a lovely walk which passes along Tramore Beach before coming back through a pine wood. The start of the walk passes through a nature reserve where a signpost explained its importance as a breeding habitat for the caterpillars of the day flying Cinnabar moth. The caterpillars feed on ragwort and absorb the toxic substances from the plant making themselves unpalatable to predators. The caterpillars have the classic, warning to predators, colours of yellow and black stripes and the adult moth’s black body and vivid red wings send out a similar warning sign to anything that might want to eat them. We had arrived as the ragwort was in flower among the dunes and virtually every plant had cinnabar caterpillars feeding on them, thousands of them. I was thinking such a large number of caterpillars facing no threat from predators must be very successful but apparently they will often totally devour their food plants and lots end up starving or resorting to cannibalism. We emerged from the dunes onto another stretch of long pristine sandy beach again almost empty of people and made our way over to where the path continued up slopes of soft grasses with a lovely patch of vivid pink ragged robin beside us and it was here, feeding on clover, I saw one of the highlights of our trip, a Dark Green Fritillary butterfly.
    Our next B&B stay had our most unlikely sighting of the trip when, walking up a hill side, we saw a llama sitting between some gorse bushes, evidently left to wander the hillside like the sheep. Our final destination in Donegal was Burt where a nature reserve runs around some of the banks of Drongawn Lough and though a fairly persistent drizzle was coming down when we reached there a walk down the path was accompanied by Meadow Pipits, Stonechat and Reed Bunting while Swifts and Sand Martins skimmed over the water catching low flying insects. We were staying in Burt because of its proximity to the town of Muff and specifically a little wood there called Lis Na Gra where there’s a well-known population of red squirrels. They’re something of a tourist attraction and are given supplementary food by a local wildlife group. We went that evening to find the wood’s location, planning on going again early the following morning when the squirrels would, hopefully, be active. A lovely wood, with stately old beeches, moss covered fallen trunks and nicely spaced Scots Pine letting sunlight beam into the woods. Jays moved through the trees and a Buzzard called from above.


  As we returned to our B&B a car in front stopped on the road and put on its warning lights. The driver got out, went to the other side of the road and picked up something. It was a young swallow, which had been hit by a passing car. On our way to the wood I’d wondered at the agility of the swallows flying so low along the same high hedged road sweeping up insects but this unfortunate hadn’t made it. I thought it very decent of the other driver to stop and try to help the bird but there was blood coming from its bill and it passed away soon after. The next morning we were up early and off to Lis Na Gra Wood again getting there by 6.30a.m. We were only there a few minutes when Lucy heard scales dropping down from a cone and we saw a beautiful red squirrel sitting high up in the Scots Pine we’d parked under. Another couple of people arrived who’d just driven from Derry. This was a favourite spot of theirs to visit and they told us a lot of newlyweds come there to have their wedding photos taken. I don’t think there was anywhere we visited in Donegal that we wouldn’t go to again and though the time we visited was great for wild flowers and butterflies we’d love to visit in spring or early summer when skylarks are singing and cuckoos are calling.
