Puffins- the spell of the Northern Monks.

The little tourist boat out of Ulver Ferry on the Isle of Mull drew towards the towering cliffs of Lunga, largest and northernmost of the Trennish Isles, the chain of rocky little basalt islands in the Inner Hebrides, north of the famous Fingal’s Cave on the isle of Staffa, that great monument to undersea volcanism and geological forces. The water we crossed was crystal clear, and rich in life, fish weaving between fronds of waving kelp beneath the surface, moon jellies, and occasionally more unusual cnidaria, drifting everywhere. At one point even Common Dolphins were leaping beside us.  We docked at a rocky promontory on the island and made our way ashore on the columnar basalt, climbing a short cliff path. The skipper had warned us the birds would hypnotise us, that we’d risk falling into a trance on the cliff path, and would have to come back to the boat without seeing the spectacular heart of the seabird city which lines the steepest cliffs. His warning was spot on, but not heeded.




We sat up on the cliff top, among the wild flowers, the Bird’s foot trefoil and Burnett moths, on the rabbit-grazed, short grass, and watched the comings and goings of the Atlantic Puffins (Fratercula arctica) for hours. Birds flew in off the clear blue water, on wings beating rapidly, with thick, vivid coloured beaks full of silver sandeels.  Adults with food swiftly disappeared into their burrows, even Puffins are not averse to nicking their neighbours’ food, and to the gulls and skuas a Puffin with food on land is an obvious target.  So, they take their food underground hurridly, and unload it for the subterranean Puffling, the single, fluffy youngster waiting in the burrow.  Puffins without bills full of food seemed to enjoy a more leisurely lifestyle, taking some time to enjoy the sun and each other, pairs bill-rubbing and calling to each other, enjoying the bonds which hold them together, companionable, almost romantic. We were, naturally, enchanted by these entertaining little seabirds, and never made the journey across the little island to the spectacular Guillemots and Kittiwakes up on the towering sea stacks.




My paternal Grandma loved Puffins, and as such I must have drawn and painted hundreds of pictures of them, and bought puffin calendars and birthday cards for her every year. Images of them adorned her home.  They were here favourite bird, and as such have always held a special place in my heart. However I was in my mid-twenties by the time I saw one, on another chain of islands on the West coast, right down in the Scillies.  Puffins tend to live far from us, on rocky offshore islands, like the Scillies or the Trennish, or famously on Lundy, where the Bristol Channel meets the Atlantic.  They visit the coastline only briefly, setting up in April, and gone by the end of July. Their vanishing act is thorough and though wintering puffins were encountered at sea from time to time, it wasn’t fully understood until the advent of geotagging.  Once their Puffling has come waddling out under the sky for the first time, and taken to the sea, the parents remaining tie to land is severed. They shed the bright, temporary sheath which has grown around their bill, and darker feathers grow around the eye, masking the big, white face patches.  They loose the ability to fly during the Autumn moult, and spend the winter upon the ocean waves, living like the penguins of the Southern hemisphere, undertaking deep dives, wings adapted for ‘flying’ underwater. The black and white countershading Puffins, plus several related Auks share with Penguins are an example of convergent evolution, where similar evolutionary pressures lead to similar adaptations.  They retain the ability to fly only because of the need to avoid land predators, and only in the breeding season, to reach their cliff-top nesting sites, and they are at their most graceful underwater.  Then, come March or April, they return to their home island, and reunite with their lifelong partner, smartly attired once again. Some compare Puffins to clowns, given their colourful features and ‘eye makeup,’ and their scientific name compares them to monks, Fratercula arctica means ‘little Brother of the North.’ The name Puffin once applied to any burrow-nesting sea bird, hence the confusing scientific name of the Manx Shearwater, Puffinus puffinus.




Puffins are members of the Auk family, Alcidae, and are related to the Guillemot and Razorbill, as well as the extinct Great Auk. The family resemblance is apparent.  Unlike their relatives, puffins nest not on precarious ledges on the cliffs, but in burrows at the cliff-tops, usually taking advantage of those abandoned by rabbits, though they are capable of digging their own, and often do, take note of the sharp grey claws on their feet next time you are close to one.  A single egg is laid underground, in a chamber carved out for the purpose. The chick remains underground in relative safety, out of the reach of Herring Gulls and Raptors which occasionally prey on Guillemot and Razorbill chicks. Puffins also differ from their relatives in their winter habits. Razorbills and Guillemots can often be seen in winter, forming big rafts just offshore from their breeding colonies, remaining visible to birders onshore all year round, but Puffins are always absent from these agglomerations, preferring to spend the winter in the vast, open Atlantic, the Bay of Biscay and the North Sea, rich fishing grounds to which they have been tracked by modern telemetry techniques.




Puffins have a number of predators, with Gulls and Arctic Skuas all too keen to steal their hard won catch of Sandeels, which the young Puffling relies on almost exclusively, and Great Skuas, Great Black Back Gulls and birds of prey such as Peregrines, will occasionally prey on the adult Puffins. They are even, in some parts of their range, still hunted by man, though not in Britain.  Climate Change, and the loss of Sandeels as a result, and as a result of overfishing remain the biggest threats they face. They are confined to relatively few colonies around the North Atlantic, largely on islands off North America and North-Western Europe, and this reliance on a small number of sites led to the Atlantic Puffin’s listing as Vulnerable by the IUCN, and they are Red-Listed as Birds of Conservation Concern.




Yet at some of their colonies they are thriving, and one of those seems to be that of the Isle of Lunga. Rich, clear Atlantic seas offer them the food they need, and they are bothered little by the tourists who continue to visit their island breeding sites in considerable numbers. They are confiding and allow close approach, and photography. A few nest still at Bempton Cliffs in Yorkshire, alongside the Gannets and the occasional visiting Albatross, and though closed this year given the unfortunate impact of the ongoing HPAI epidemic, the Farne Islands still host a healthy population of these charming, entertaining little sea birds. Go and see them.
