Alpine Chough or Western Jackdaw?
Here's how to tell the difference
Alpine Chough
Western Jackdaw
Alpine Chough
Pyrrhocorax graculus
Also known as: Yellow-Billed Chough
General appearance
The Alpine chough, a species of bird from the crow family, is characterized by its vivid black coloration. It has a strong, yellow bill and red legs. The species displays a sleek profile, with a short neck and round head, a height of about 39-40 centimetres and a wingspan of approximately 75-85 centimetres.
Male vs female
Male and female Alpine choughs have similar appearances, making it challenging to distinguish between the sexes. Both possess the same striking contrast of black body, yellow beak, and red legs. There are slight differences in size, with males typically being larger, but this isn’t a consistent identifier.
Juvenile
Juvenile Alpine choughs greatly resemble adults. However, they can be identified by their softer plumage, duller legs and beak. Their beaks are also shorter and rounder than those of adults. As they mature, their features develop the sharper, more vibrant characteristics of adult choughs.

Coloeus monedula
Also known as: Eurasian Jackdaw, European Jackdaw, Jackdaw
General appearance
The Western Jackdaw is a stocky bird, somewhat smaller than a crow, measuring approximately 33 cm or 13 inches. It is primarily black, but features a distinctive grey nape. A standout feature is the bird's white or blue-white eyes. It has a large size, with a sharp contrast between the black crown and pale gray nape and typically displays a rounded, square-tipped tail and broad, fingered wings.
Male vs female
Western Jackdaws are sexually monomorphic, meaning males and females are similar to each other in size and colour. Both sexes share the same notable features, including the bold white or pale blue eyes, grey nape and predominantly black plumage.
Juvenile
Juvenile Western Jackdaws closely resemble adults but can be distinguished by their duller, more uniform plumage colouration. They also have dark eyes that turn pale only as they mature, making them easily distinguishable from adult Jackdaws with their distinctive white or pale bluish-white eyes.

Visual differences
The Alpine Chough, larger at 15-16 inches, sports vivid black plumage, a distinct yellow bill, and red legs. In contrast, the Western Jackdaw, smaller at about 13 inches, features primarily black feathers with a distinctive pale gray nape and white or pale blue eyes. The Jackdaw's beak is more typical in coloration and lacks the Chough's vibrant yellow. Additionally, Jackdaws have a rounded, square-tipped tail and broad, fingered wings. These features provide clear visual distinctions between the two birds.
Key differences and behavior
The Alpine Chough and Western Jackdaw both demonstrate remarkable intelligence and adaptability, yet exhibit distinct behaviors that facilitate differentiation in the field. The Alpine Chough is a high-altitude specialist, nesting on steep cliffs up to 13,000 feet, and demonstrates lifelong mate fidelity. It excels in aerial acrobatics during courtship and primarily feeds on insects, small mammals, and seeds. In contrast, the Western Jackdaw, inhabiting diverse environments from coastal cliffs to urban areas, is exceptionally social and ingenious, often seen in playful pairs. It has a flexible diet, consuming insects, seeds, and garbage. Both species form long-term pair bonds, but the Jackdaw is renowned for its social antics and strategic foraging behavior.
