【 摘 要 】

Weka (Gallirallus australis) can be aged accurately up until 50 days old using leg and bill measurements, and then less accurately up to 180 days old using plumage development, wing spur shape and iris colour. Weka less than one year old can be distinguished by their remex tip and wing spur shape. Beyond one year, Weka can only be placed into age groups, using wing spur shape.
