(Strigopidae; Ϯ Kakapo S. habroptilus) Gr. στριξ strix, στριγος strigos  owl; ωψ ōps, ωπος ōpos  countenance; "STRIGOPS.  Bill higher than broad, slightly compressed, and grooved on the sides; the culmen much curved to the tip, which is acute; the lateral margins dentated in the middle; the lower mandible with the gonys broad, rounded, and much grooved longitudinally, and the base of both mandibles covered by the basal feathers, with the shaft of each prolonged into hairs; the nostrils basal, lateral, large, and rounded.  Wings rather short and rounded, with the fifth and sixth quills equal and longest.  Tail moderate, weak, and much rounded, with the end of each feather rather pointed, and the shafts projecting beyond the web.  Tarsi short, robust, and covered with rounded scales.  Toes unequal, and covered with quadrate scales, except at the end of each toe where the scales are transverse; the claws long, strong, and slightly curved.  This remarkable bird was found in one of the islands of the South Pacific Ocean. Its manners and habits are unknown; but, from the appearance of the bill, I am induced to suppose that it feeds on fruits that are enveloped in a strong hard coating.   S. habroptilus G. R. Gray." (G. Gray 1845); "Strigops G. R. Gray, Gen. Bds., 2, 1845, p. [426], pl. CV. Type, by monotypy, Strigops habroptilus G. R. Gray." (Peters 1937, III, 141). The very rare Kakapo is also known as the Owl Parrot, because of its owl-like facial discs and soft body plumage.
