Justification for EICAT assessment


On Macquarie Island predation by the Weka may have been sufficient to reduce the endemic Macquarie Island Parakeets (Cyanoramphus erythrotis) from abundance to global extinction and may also have destroyed the endemic Macquarie Rail (Gallirallus philippensis macquariensis) which was globaly extinct by 1984. The crucial factor in the bird's extinction appears to have been the successful liberation of rabbits (Oryctolagus cuniculus) in 1879. This led to great increases of feral cats and introduced wekas (Gallirallus australis) and presumably to greatly intensified predation on parakeets. (Taylor 1979).

Description of impacts
The Weka is responsible for the global extinction of the Macquarie Island Parakeet and Macquarie Rail, the local extinction of the Blue Petrel on Macquarie Island and for the decline of several bird species in New Zealand. It preys on bird eggs, chicks and invertebrates and can alter the characteristics of vegetated areas.
