It was like searching for a needle in a haystack – instinct told me that ptarmigan were watching my every move on this 3,000ft high boulder field in the mountains by Glenshee, but their cryptic plumage had merged these subarctic grouse seamlessly into the stark lunar landscape.
Their droppings lay scattered around the summit of Carn Bhinnein and it almost seemed as if the birds were taunting me by their near presence. Camouflage is their means of survival and despite my frustration at being unable to find any ptarmigan, a begrudging admiration swept my mind at their ability to maintain perennial concealment.
After much fruitless searching, I abandoned the quest and instead focused on a cushion-like ball of hairy fluff nestled in among the rocks. It was woolly fringe-moss, a high mountain specialist with the most appropriate demeanour of appearing to have fleece-like insulation to protect itself from the cold mountain air.
It is a common moss of uplands, especially open, stony, windswept ridges and plateaux, and features intricate wispy twists and curls. Nearby lay another high montane specialist – fir clubmoss – which is more closely related to ferns than mosses. The rocks around me were encrusted with colourful lichens, and it felt like I had been drawn into a mysterious primeval world, surrounded by nature’s earliest creations.
I hunkered down in a gully out of the cool wind to ponder ptarmigan. They are mountain chameleons, their plumage changing with the seasons, merging and matching in sympathy with the surroundings. In winter, ptarmigan turn almost completely white, but the spring and summer plumage is more of a mottled grey and brown, with flashes of white. The feet are completely feathered, which not only prevents heat loss, but acts as a useful pair of snowshoes in winter.
Ptarmigan eat the leaves and shoots of arctic-alpine plants, as well as insects in the summer. The crowberry is important and ptarmigan feast upon their glossy black fruits in late summer.
Rising to my feet, I wandered further over the boulder field – five more minutes looking for ptarmigan, then I would call it a day. The five minutes stretched to 10, and then to 15, but the ptarmigan remained elusive, so I descended back down into a nearby glen. Late-season meadow pipits and skylarks bounded up in the air before me and a kestrel hovered above on quivering wings.
By a craggy knoll where a lone sentinel rowan stood, the mewing calls of a family of buzzards whirled across the breeze. It was a somewhat monotonous call, more akin to a seagull than a bird of prey. Soon, I spotted two of the buzzards, tumbling upwards on widespread wings before they swept away over a shallow-curved ridge.
I looked back up the glen towards the distant conical top of Carn Bhinnein from which I just descended, and wondered whether the ptarmigan were still watching me from their lofty vantage points in among the high boulder fields – invisible and inscrutable to the very last.
