[First paragraph…]The weka (Gallirallus australis) is a remnant species of the diverse suite of avian predators known to have consumed petrels on mainland New Zealand and its offshore islands. The paper by Harper (2006) detailing weka predation of sooty shearwater (Puffinus griseus) chicks and eggs is therefore a welcome contribution to understanding the ecological relationships between petrels and predators. Unfortunately, I believe that Harper (2006) mis-cited Hawke & Holdaway (2005) in his assertion that weka may present a threat to breeding Westland petrels (Procellaria westlandica).
