Eudyptes sclateri breeds on the Bounty and Antipodes Islands (1 km2 and 20 km2 respectively), New Zealand. In 1978, the population on the Bounty Islands was estimated at 115,000 pairs, spread over nine tiny islands6. A survey in 1997-1998 estimated a total of 28,000 breeding pairs1,2. Census methods differed, making comparisons less useful7, but the results suggest that a large decline may have taken place. The population on the Antipodes in 1978 was believed to be of a similar size to the Bounty Islands in the same year. In 1995, ground surveys indicated c.49,000-57,000 pairs7, representing a decline of c.50% in 20 years, and there have been further decreases since8,9. These declines are supported by photographic evidence. The population on Campbell Island numbered 20-30 pairs in 1986-1987, but no breeding was seen. A few hundred birds bred there in the 1940s7. Winter distribution at sea is largely unknown, the only records being from the Cook Strait and off the east coast of the South Island5.
