Nucifraga caryocatactes

Contents

Identification

32 - 34cm. A distinctive, medium-sized corvid:

  • Dark brown plumage with white spots and streaks, most densely on side of head
  • Plain dark brown rump and uppertail-coverts
  • White undertail-coverts and lower belly
  • Glossy black upperwing
  • Glossy black tail with white feather tips
  • Dark brown eye
  • Black bill and legs

The subspecies differ in density and size of white spots and size of the bill.
Sexes similar, jufeniles have dull brown wings and a broad white tip on the median coverts.

Distribution

Scandinavia right across northern Europe, mountains of central Europe, Siberia and to eastern Asia, including Japan and the Himalayas.
Locally common.

Taxonomy

Eight subspecies accepted, more have been proposed:

Large-spotted Nutcracker was formerly inclued in this species. The subspecies hemispila is sometimes considered to belong to Large-spotted Nutcracker too.

Habitat

Taiga conifer forests and mixed conifer and birch forest. Occurs from lowlands up to 4000m in Nepal.

Behaviour

The diet includes the nuts and seeds from pine trees, spruce and hazel trees. It also takes insects, birds' eggs and nestlings, digging out bumble bee and wasp nests to take the grubs.
Stores large quantities of nuts in his winter territory. Caches them often at the base of a tree, behind moss on rocks, crevices in a tree bark or simply on the ground near a rock or a small sapling. As it forgets some of it this bird plays an important role in the dispersal of several tree species.
Usually seen in pairs or family parties and has little fear of humans.
The nest is usually built high in a conifer. 2-4 eggs are laid and incubated for 18 days. Both sexes feed the young which are usually fledged by about 23 days.
Most populations are resident but in some years big movements have been recorded and birds from Siberia (macrorhynchos) are known to reach Europe in certain winters.
