The nutcracker is a Jay-like bird of the genus Nucifraga, in the crow family Corvidae, order Passeriformes. There are two species: one in the Old World and one in the New World. The Old World nutcracker (Nucifraga caryocatactes) is found in areas of coniferous forest in Asia and parts of Europe, particularly in mountains. About 30 centimetres long, it has a brown back, with a long white spot on each feather, dark brown head, white tipped outer tail feathers, black feet and a powerful black bill. It feeds on conifer seeds. The nest is a big, clumsy structure, and in it about three eggs are laid, which are very light green, spotted with pale brown. Irregularly, there is a mass migration of nutcrackers from Siberia to western Europe. Research Nutcracker
