Previous exploration and ornithology in the Rauer Group are reviewed. Estimates of the nesting populations of southern fulmars and Antarctic petrels are compared with censuses conducted in 1983/84 and 1984/85. Population estimates varied considerably between years, and within the same year between different observers. To remedy this situation the three islands with sympatric breeding populations of the two species were divided into counting units, which are detailed with photographs. The total populations of surface-nesting petrels are in the order of 14000 pairs of fulmars, 2500 pairs of Antarctic petrel and 400 pairs of cape petrels. Chick survival was estimated at the time of banding and varied considerable between species, islands and years.
