Kākā pōria (bird leg ring)

Kākā pōria are small leg rings usually fashioned from bone or stone materials. They were used to confine the movements of young kākā (Nestor meridionalis) parrots, which, after being caught, were held prisoner by the leg rings. The captured kākā became tame and were then referred to as mōkai (captive or pet). During the fowling season, these pet kākā were taken into the forests where they were made to cry out to attract wild birds. Wild kākā, being curious and sociable, were attracted in great numbers by the tame birds' cries.

Snaring methods
As the wild birds alighted on nearby branches, the mōkai handlers would be lying in wait with mutu kākā (snares for parrots). Some birds would alight on a snare's carefully arranged horizontal perch, and a cord would be jerked trapping the legs of the birds against the protruding upright of the mutu kākā. The wild birds were summarily dispatched and bagged for the journey home.

Fine pendants
Kākā pōria, when not attached to the legs of tame birds, were worn as pendants. Some, especially those fashioned from pounamu (New Zealand greenstone), required sophisticated technical knowledge to make because of the hardness of the material and the finely carved details such as the holes on the outer edges that accommodate the cord. Kākā pōria often became valued family heirlooms and were passed down from generation to generation.
