Māori had many instruments for imitating bird calls - leaves and grasses, tubular plant stems, and hollow stones. The karanga weka pictured is shaped like a small nguru, or nose flute. It can be played to sound just like the weka bird. This karanga weka was carved by Clem Mellish and gifted to Te Papa as part of the Haumanu collection in 1997. It is made from pounamu (greenstone).
