Common Raven Image

COMMON RAVEN

SOUND
  • Typical call is a loud, guttural croak, but makes an astonishing variety of other strange noises.
Carrion Crow Image

CARRION CROW
(corvus corone corone)

APPEARANCE
  • The quintessential big black crow, without obvious field marks.
  • Smaller than the Common Raven, which has longer, wedge-shaped tail, heavier bill, shaggy throat, and deeper voice.
  • Ravens soar and glide readily, whereas crows typically flap continuously.
BEHAVIOUR
  • Common in varied open and semi-open habitats from towns and farmland to open woodland and moorland.

Hooded Crow Image

HOODED CROW
(corvus corone cornix)

APPEARANCE
  • Distinctive crow with an ashy gray body and contrasting black head, wings, and tail.
  • Essentially unmistakable unless seen in poor light or at a distance.
  • Birds average paler in eastern parts of range, with “Mesopotamian Crow” of Iraq and southwestern Iran being almost black-and-white.
  • Hybridizes with Carrion Crow where the two overlap.
BEHAVIOUR
  • Found in varied open and semiopen habitats from towns and farmland to open woodland and moorland.
  • Found in pairs or small groups, not usually in large flocks except at roosts.

White-Necked Crow Image

WHITE-NECKED CROW
(corvus leucognaphalus)

APPEARANCE
  • Appears all black; the namesake white neck feathers are only visible during courtship.
  • Note its bright red eyes.
  • The only other large black species sharing its range is the Palm Crow, which has dark eyes and is a bit smaller.
  • Additionally, the White-necked Crow has a relatively long, pointed bill with limited feathering atop when compared with that of the Palm Crow.
  • Note smoother, steadier wingbeats compared with faster, choppier wingbeats of crows.
BEHAVIOUR
  • Occupies a wide range of habitats including agricultural fields, but prefers wet upland woods.
SOUND
  • This species vocalizations are remarkably parrotlike and rather unlike those of other crows.
  • Calls include an upward inflected, rolling, and drawn out "wreh", usually given in series as well as a variety of shrill burbling or gobbling sounds.
Pied Crow Image

PIED CROW
(corvus corone albus)

APPEARANCE
  • Handsome black-and-white crow.
  • Strong flier that will fly high and occasionally soar.
  • Overall shape and size similar to some raptors, but none of them show Pied Crow’s contrast between black tail, white underparts, and black head.
BEHAVIOUR
  • Found in almost all habitats except driest desert and thick rainforest.
  • Feeds by walking along the ground.
SOUND
  • Common call is a typical crow "crawk".
Jackdaw Image

EURASIAN JACKDAW
(corvus monedula)

APPEARANCE
  • Distinctive, small social crow with contrasting, silvery-gray neck shawl and staring whitish eyes; juvenile has duller shawl and eyes.

  • Distinctive shape in flight, with rather long, swept-back wings and long tail.
  • Note smoother, steadier wingbeats compared with faster, choppier wingbeats of crows.

Rook Image

ROOK
(corvus frugilegus)

APPEARANCE
  • Large, glossy black crow.

BEHAVIOUR
  • Inhabits farmland and other semiopen areas with hedges and groups of tall trees, where nests in rookeries.
  • Forages on ground, usually in flocks, and associates readily with crows and jackdaws.
