Range Description

Thalassarche impavida breeds only on the northern and western coastline of Campbell Island (111 km2) and the tiny offshore islet, Jeanette Marie, New Zealand. The total population was estimated to be 19,000-26,000 breeding pairs (Moore and Moffat 1990), with the most recent censuses in 1995-1997 giving an estimate of 24,600 pairs (Moore 2004). Numbers decreased steeply between the 1970s and 1980s: one colony declined at a rate of 5.9% per year between 1966 and 1981, and 10.5% per year between 1981 and 1984. However, numbers have been either stable or increasing slightly since 1984 (Waugh et al. 1999a),with a 1.8% increase recorded in selected colonies between 1992 and 1997 (Moore 2004). Its non-breeding range is confined to southern Australian waters, the Tasman Sea and the south Pacific Ocean (Croxall and Gales 1998, Waugh et al. 1999b). Breeding adults forage from South Island, New Zealand, and Chatham Rise southwards to the Ross Sea (Waugh et al. 1999c, BirdLife International 2004).
