Kea ( Nestor notabilis )
|Lesson , 1830|
Today the genus only consists of two recent species that occur in New Zealand . A third species, the thin-billed nest , lived on the Norfolk Islands north of it until the middle of the 19th century , and a fourth on the Chatham Islands east of the South Island . Nestor parrots are large and powerfully built parrots. The sexual dimorphism is only weakly developed in all species. They are characterized by a short, square tail. The shaft of the control springs protrudes over the flag and forms a spike-like point. The wax skin is partially covered by bristly feathers. The underside of the upper beak has longitudinal saw-like notches. There is a hair-like hem at the tip of the tongue.
