The Cliff Walk

At this time of year the Cliff Walk between the towns of Bray and Greystones turns into a spectacular Eden. There is an otherworldliness about it that is difficult to describe with mere words, even when accompanied by photos. Now, in June, there is a wildlife extravaganza on show, not to mention the fantastic scenery. The best way of seeing the Cliff Walk is to start in Bray, in late morning or early afternoon, after a hearty breakfast, and travel south to Greystones, in time for a late lunch or early dinner, and thereby moving with the sun so you are not constantly in the shade. This is essential for photos. In the heat of June you will need to wear a hat, sunglasses optional. The burn factor on the cliffs is equal to the Sahara, and water is as vital here too.

The seabirds are all breeding now: kittiwakes down near the crashing waves, cormorants on rocky outcrops along embankments; not to mention shags, guillemots, black guillemots, and razorbills.

Soaring above all of these birds are the most spectacular cliff-dwellers of all, the Fulmars. These birds look remarkably like gulls in colouring, but their albatross-like heads and unusually-shaped and patterned beaks betray a very different lineage. Fulmars are actually petrels, true seabirds that spend most of their lives on the wing, soaring above the waves, and diving to snatch fish prey. They hav unusual pipe-like nostrils, like the radiators above the engines of World War II fighter planes, which is why they are also known as “tube-noses”.

Fulmars are mostly North Atlantic birds, and Ireland is in the southern limit of their range. In June they start to pick out clefts and ledges on cliffsides on which to lay their eggs and raise youngsters. They are extremely vocal at these sites as they have to guard them from other Fulmars, nest-sites being at a premium. They nest just below and even above the Cliff Walk, singing loudly, and sounding just like penguins.

Meanwhile, Kestrels, Herring Gulls and the gigantic and highly predatory Great Black-backed Gull hover along the cliffs looking for an easy meal. For the Great Black-backed Gull this can also include adult birds of any species, although the dagger-like beaks of Gannets mean they are generally avoided. To deal with predators of this nature the Fulmar nestlings have a secret weapon. If anything gets too close (and this includes humans) they projectile vomit a stinking oil smelling of rotting fish. It is said to be so potent that not only can it not be washed out of clothes, but it takes days before it will come off human skin.

Probably the most unusual and beautiful birds to be seen along the cliffs are the fantastically aerially-acrobatic Rock Doves. These birds are believed to be the ancestors of the pigeons (the so-called “winged rats”) that live in cities, and they do look very similar, but are far more beautiful. Look at the iridescence of the the one in this photo, taken by Trevor.

With all of the birds around you would think flowers would be far less noticeable, but there are several species that manage to steal some of the limelight even from these. Dog Rose, vetches and Honeysuckle form dense jungles of vegetation along the more sheltered, but sunny area of the path. However, by far the most colourful and impressive of all of the wild flowers is the Red Valerian (Centranthus ruber), which grows in masses all along the walls, cliffs and any available areas by the path, particularly in the less windswept areas.

Some plants are less impressive, but can inspire quite spectacular events. One of those events you will encounter on the Cliff Walk in June is a massive swarm of inch-worm caterpillars of the Magpie Moth (Abraxis grassulariata). These caterpillars thrive on a small tree called Evergreen Spindle (Euonymus japonica), which can be found all across the cliffs of Bray Head. In June the caterpillars set out to find places to pupate, and can be seen across walls and fences on the Cliff Walk in their hundreds.

These little beauties are not the only insects of note to be seen along theCliff Walk in June. If you are lucky you may catch sight of what appears to be a sulphur-yellow butterfly. Actually, I’m only joking. It is extremely common on Bray Head. This is, in fact, a day-flying moth, the Speckled Yellow (Pseudopanthera macularia) that in Ireland is very rare outside of the famous Burren in western Ireland.

Closer to Greystones the massive rock cliffs give way to sand cliffs which provide a very important habitat for one of the more interesting bird species that visits Wicklow in Ireland. This species is the Sand Martin (Riparia riparia), which is very closely-related to the House Martin (Delichon urbica), that nests under the eaves of houses. The Sand Martin will only nest in holes in sand banks. The Greystones side of the Cliff Walk is probably the very best place in Wicklow to see these birds.

After taking a little safari between two-and-a-half and three hours over the Cliff Walk, you will find you have a very impressive collection of photographs

Proceed with caution…

A few years ago I discovered a unique trick. I was able to leap clear over a big metal farm gate, without touching it, while wearing heavy boots. I have only attempted this remarkable feat on one occasion, when a large herd of cattle stampeded down hill towards me at a gallop.

The Irish countryside is probably one of the safest you can visit anywhere on earth, but like all countrysides it does have some small dangers. Try to keep to tracks and paths and be very wary of crossing fields, because there are often bulls and other semi-wild cattle about. I know of one bull which once managed to topple over a tractor. Most cattle in Wicklow are beef cattle, big muscular creatures that have become progressively less used to being handled by people since farming methods changed in the 1990s. It is agreed by almost all naturalists that domestic cattle are the most dangerous aspect of the countryside, and they do kill a small number of people in Ireland each year. Remember, if you see a fence it’s there for a reason, usually to keep a big animal in. Even if a field looks empty, a large territorial bull could be lurking behind a bush, or lying down in long grass.

A Charolais bull...the last thing you want to see when you're crossing a field.

But now we are in June it’s the smaller creatures that can be a bit of a nuisance in the countryside. In June many species of horsefly emerge. The females usually wait along hedgerows, landing on large mammals that pass by to drink their blood. Some of them will target human beings and can give a bite that you won’t feel until it’s too late, as the saliva of the horsefly is designed to quieten nerves. Watch out for any insect that flies quietly, almost like a moth, and seems to want to land on your clothes. If it is slow-moving and with extremely colourful eyes, then you have found one. They are not swarming insects, but one person could attract a number of individuals if passing through dense vegetation in or near a hedgerow.

Here’s one that landed on my brother. As male horseflies are harmless nectar-feeders they might land on a brightly-coloured shirt. But the female will be after only one thing…

High drama in May

It has been a somewhat blustery and cool May, with a many showers, but according to a new version of an old saying: “Wet and windy May, fills the barns with corn and hay”. But the rain and the sunlight combine to support lush vegetation in Wicklow, and there are dramatic scenes everywhere. The Hawthorn, the sacred tree of the ancient druids, bursts into blossom and crowns the spring and announces the summer.

Hiding on the blooms of dense plants like the Russian Comfrey (Symphytum x uplandicum) the small predators aim to catch big prey. The Flower Crab Spiders are especially brazen, and can even be seen attempting to snatch bumblebees.

Flower Crab Spider (Misumena vatia) waits in ambush to snatch a bumblebee collecting nectar from Russian Comfrey. It failed, and some bees even knocked others away from the flowers.

Even on the ground in towns and villages there is drama and action: watch for ants hurrying back to their nests with food and prey. Their incredible strength is fascinating in itself.

However, not all of the action near to the ground is of a predatory fashion. Some creatures have no problem finding food in abundance, and therefore have plenty of time for other activities. On the large fleshy leaves of the Broad-leaved Dock (Rumex obtusifolius) you will often see beautiful sweet-wrapper shiny green beetles calmly munching on the vast leaves. This is the Dock Leaf Beetle (Gastrophysa viridula), a very distinctive species of leaf beetle, due to the enormous abdomen of the pregnant female. She becomes swollen with hundreds of eggs, and is usually garded closely by a mate, or a suitor waiting for her to lay her eggs so he can take his turn fathering offspring.

All of this excitement between waist and ground level is wonderful to observe, but it can distract you from incredible seens high above. A chance glance at the Wicklow clouds could bring your eye into line with a flock of fleeing pigeons or doves, and just in time to see a Peregrine Falcon slowly wheeling above. If you can see it clearly then your back will almost certainly be to the sun, and the great predator’s prey will be even further from you than the falcon, because this bird likes to fly at it prey from the direction of the sun, where it can be seen least well, if at all.

Although a very similar species of falcon, the Hobby (Falco subbuteo), can occasionally be found in Wicklow, this Peregrine is a stouter bird with wings that appear wider from front to back when seen in flight. It has recently been dicovered that Peregrines living in cities and towns will hunt actively at night, usually striking their night-flying prey from beneath, in the ambush-style of their sea-dwelling equivalent, the Great White Shark. It is theorised that the lights from buildings illuminate the undersides of birds flying above them, allowing the Peregrine to see its prey in the dark, although it might also be argued that it is using the lights of the buildings in the same way it uses the sun during daylight hunting, to prevent its prey from seeing it.
