Snospurven! Snow Buntings, Plectrophenax nivialis, and all I know about them.

 At the lower station of the Cairn Gorm funicular railway, just above Loch Morlich, not far from Aviemore and part of Britain’s most noted Ski resort, there is a small, and usually astoundingly busy car park, surrounded by high end tat shops and various small, ski-related enterprises.  Emma and I visited the Cairngorms’ eponymous mountain in the hope of catching up with the confiding Ptarmigan for which the lower slopes are noted. The heavens had, the night before, dumped impressive volumes of snow on the towering landscape, and, though some paths up to the Slopes were already well trodden, the mountains, for miles, were coated in a thick, deep blanket of white, softening their ragged edges. Snow brings a curious sense of silence, and seemed to dampen the hubbub of excited skiers, and we looked down on a winter wonderland, snow hanging in the branches of the pine woods of Rothiemurchus, all the way down to the loch shore and beyond.

There were, despite this being apparently the only centre of human activity for miles here, special, and especially beautiful, birds here. A small band of Snow Buntings perched on the sloping roof of the ski centre. They fluttered down to pick about in the snow beside the green, angular, corrugated iron structure, flashing black and white wings. They allowed close approach, unafraid of the people around. Eventually a small crowd of photographers, armed with long lenses, gathered, and the Snow Buntings were keen and obliging models. Charming birds of high altitudes and the high arctic, last time I visited the flock, apparently a fairly regular fixture around the lower car park and the higher Ptarmigan restaurant during the winter months, had already melted away to their breeding sites high up in the crags. Flocking, and moving around these lower slopes, and being confiding, are winter behaviours. They nest high in the rocky landscapes, males singing atop deserted and windswept crags, where people very seldom tread. Arctic/alpine specialists, they breed right up into Arctic Norway, Arctic Russia, Iceland and Arctic Canada, places of icy extremes. When I visited Arctic Norway, in high summer, ‘Snospurven,’ a ‘common breeding bird,’ were nowhere to be seen.  Both sexes become whiter in summer, as they feed around the snow line, grabbing the insects which drift up on thermals, to find themselves dropped just above the snow line, an easy meal for the Snow Buntings to take back to their chicks.  During the last ice age they thrived across Europe. What impact climate change will have on such specialists as these remains to be seen.

Britain’s only breeding Snow Buntings are the few hundred pairs in the highlands, but in winter, more do appear in the country, and tend to choose a habitat which couldn’t be more different to the Cairngorms. They gather in small parties on stony ground, usually on shingle beaches, and are a regular fixture in some spots along the East coast. Here, their white-and-sandy winter plumage provides remarkable camouflage, blending readily with the Carstone and iron stained Hunstanton chalk pebbles of North Norfolk.  Here too they can be confiding, on a recent trip to Titchwell it was a joy to find these small and cheerful little birds scuttling around our feet. They can turn up as far South as Kent and Essex, but favour the North and East, making landfall at night as they cross the North Sea from Scandinavia and beyond, from places which make the North Norfolk winter seem mild.

When we returned from our fruitless trudge through the snow on Cairngorm, without having seen a Ptarmigan, and a pair of noisy, cronking Raven the only new species on our day list of two species, we found 30 or so Snow Buntings now gathered, and a small crowd of photographers admired them, from just a couple of metres away.  What a privilege to encounter such charming and special birds, at such close quarters.
