How to Identify Alpine Chough Feathers

What Alpine Chough's Feathers Look Like

Alpine Chough is an all-black corvid of high mountain ranges, and its feathers show a glossy, unmarked black plumage with a subtle blue-green sheen, most visible on the back and wing covert feathers in direct light. Flight feathers are black, broad at the base, and notably deeply notched or "fingered" at the tip — an adaptation for efficient soaring in thin mountain air that gives the primaries a distinctly slotted silhouette compared to less specialized corvids. Tail feathers are black and slightly rounded. There is no white or contrasting marking anywhere on this species — a genuinely all-black bird from bill to tail.

Step-by-Step: Is This Feather From a Alpine Chough?

• Check for total blackness. No white patches, pale edging, or barring anywhere on the feather.
• Look for blue-green gloss. Tilt the feather in good light — a subtle blue-green sheen, distinct from a flat, matte black, supports a chough or similar glossy corvid.
• Examine the primary tip shape. A deeply notched, "fingered" tip on a flight feather suggests a bird adapted for soaring, consistent with mountain-dwelling choughs.
• Measure the feather. Medium corvid-sized, smaller than a Common Raven's feathers but similar in scale to a Jackdaw's.
• Consider elevation. A glossy all-black feather found at high elevation near cliffs or alpine meadows fits this species far better than lowland corvids.

Similar Species & How to Tell Them Apart

• Red-billed Chough: Nearly identical all-black glossy plumage, essentially indistinguishable from Alpine Chough by feather alone since both species share the same blue-green sheen and deeply fingered wingtips. The two differ mainly in bill color and shape (not feather traits), so elevation and range are the best practical clues — Alpine Chough tends to favor slightly higher elevations where the two overlap.
• Common Raven and Carrion Crow: Larger overall, with less pronounced blue-green gloss and less deeply slotted wingtips than the more soaring-adapted chough.
• Western Jackdaw: Shows a paler gray nape and ear-covert area rather than the uniform all-black plumage of Alpine Chough, making it easier to rule out.

Where & When You'll Find Them

Alpine Chough lives in high mountain ranges across Eurasia, including the Alps, Pyrenees, and Himalayas, typically well above the treeline on cliffs, alpine meadows, and rocky slopes. It is often seen scavenging around mountain huts, ski resorts, and tourist sites at high elevation. The species is largely resident, though some birds move to lower elevations in severe winter weather. Molt occurs mainly after the summer breeding season, and feathers are most often found on high alpine cliffs, pastures, and around human activity at altitude.
