As a fisheries biologist I took part in a number of voyages on research and fisheries vessels in the fishing areas off Angola, Namibia, South Africa and Mozambique from 1966 until 1990. Some of the ornithological results of these voyages have been published (Lambert 1967, 1968, 1969, 1971, 1975a, 1975b, 1980, 1983, 1984, 1988), but the majority of my data has not yet been reported. The following list deals with sight records of rarely reported seabirds from the offshore regions from Angola to southern Mozambique from 1968 until 1988. Several species are newly recorded for their respective countries.
