Yellow-Billed Chough (Pyrrhocorax graculus) lives in alpine meadows and scree slopes across Mountainous regions of southern Europe, north Africa, and Asia. Its conservation status is Least Concern.

A real field recording of the Yellow-Billed Chough, made in the wild.
The Alpine chough has nested at 6,500 m (21,300 ft), the highest altitude recorded for any bird species. This exceeds the breeding limits of most alpine birds, which normally nest between 1,260-2,880 m in Europe, 2,880-3,900 m in Morocco and 3,500-5,000 m in the Himalayas. By using cliff-side cavities at such heights, the chough exploits habitats where few competitors can survive.
Alpine choughs have been seen trailing mountaineers on the ascent of Mount Everest at 8,200 m (26,900 ft), demonstrating that they can operate well above their usual breeding ceiling. Their normal breeding range tops out around 5,000 m in the Himalayas, so following climbers shows an ability to exploit brief opportunities at extreme elevations. The birds use the same buoyant, acrobatic flight that allows them to navigate steep up-draughts on cliffs.
Their eggs possess fewer pores than lowland bird eggs, cutting water loss in thin air. This reduction in evaporation enables the chough to breed on high cliffs where atmospheric pressure is low and moisture is scarce. In addition, embryos develop haemoglobin with a genetically determined high affinity for oxygen, further supporting development at altitude.
During the cold months the Alpine chough supplements its fruit-based diet by eating faeces, a habit documented in a 2026 study. Researchers found that almost half of the 1,442 droppings examined were consumed, providing nutrients from partially digested food when snow limits other sources. This coprophagy occurs regardless of temperature or time of day, allowing the birds to maintain energy balance in harsh winter conditions.
In winter the Alpine chough often gathers around ski resorts and mountain lodges, where it perches by hotel windows awaiting scraps. This behaviour makes the birds a familiar sight to tourists, who enjoy watching them, but it can irritate hotel owners who see the birds as a nuisance. Their willingness to approach tourist sites for supplementary food reflects their flexible foraging strategy in high-altitude environments.

About the Yellow-Billed Chough
In the rugged, windswept landscapes of the mountainous highlands, the Yellow-Billed Chough reigns supreme, its glossy black plumage glistening like the darkest onyx as it soars effortlessly on outstretched wings, its melancholic calls echoing through the crisp, thin air. With an effortless elegance, it dances on the updrafts, its acrobatic maneuvers a testament to its remarkable agility and adaptability, allowing it to thrive in some of the most inhospitable and breathtakingly beautiful environments on Earth. As it alights upon a rocky outcropping, its bright yellow bill flashes like a ray of sunlight, a beacon of vitality in a world of stone and shadow.
