Western Jackdaw

The Western Jackdaw is a compact, sociable member of the crow family, often seen in noisy flocks wheeling around church towers, cliffs, and old buildings. Its comparatively small size and quick, agile flight distinguish it readily from larger crows and rooks with which it often associates.

Jackdaws are widespread residents across Europe, North Africa, and western Asia, thriving alongside humans in towns and villages as well as in more natural cliff and woodland edge habitats.

A Jackdaw feather is usually recognized by its comparatively small size for a corvid and, on head and neck feathers, the soft silvery-grey tone that contrasts with the glossy black plumage found elsewhere on the body.

Size and shape

• Notably smaller and more compact than feathers from crows, rooks, or ravens, reflecting the Jackdaw's smaller overall size among corvids.
• Flight feathers are proportionately shorter and less broad than those of a Carrion Crow.

Color pattern

• Most body and flight feathers are solid glossy black with a slight blue-grey sheen.
• Feathers from the nape and sides of the neck show a distinctive pale silvery-grey wash, unlike any other common black corvid.

Shaft and texture

• Shafts are dark and the feathers have a fairly soft, dense texture typical of corvids, but reduced in scale compared to the larger species.

Confusion species

Compared to a Rook or Carrion Crow feather, a Jackdaw feather is noticeably smaller with a less imposing profile; the grey-washed nape feather is diagnostic and not shared by any other common black European corvid.

Adult Jackdaws have a glossy black crown, face, throat, wings, and underparts, contrasting with a silvery-grey nape and hindneck. The eye is pale grey-white, giving a distinctive staring appearance.

Males and females look alike. Juveniles are duller and sootier overall, with a darker eye that lightens with age and less contrast on the neck.

Jackdaws undergo a complete molt after breeding in late summer, replacing flight and body feathers before the colder months.

Jackdaws nest colonially in cavities, using holes in old buildings, church towers, cliffs, quarries, and mature trees. They forage in open farmland, parks, and grasslands, often in mixed flocks with Rooks.

The species is largely resident across its wide range spanning Europe, North Africa, and western and central Asia, with some northern and eastern populations shifting south in winter.

Jackdaws are highly social, gregarious birds that feed on a broad diet of invertebrates, seeds, and scraps, often foraging on open ground in flocks. They frequently associate with Rooks and other corvids at communal roosts.

They nest in cavities, laying eggs on a lining of grass and other soft material within tree holes, cliff crevices, or building cavities. Their call is a sharp, metallic 'chak' or 'jack', often repeated in flight.

A feather showing small size, glossy black color, and a grey-washed neck patch found near old buildings, cliffs, or farmland is a strong indicator of Jackdaw.
