Three rookeries of Adélie Penguins (Pygoscelis adeliae) at Coulman Island, Antarctica, were last reported in 1964. Their size was then only roughly estimated and their positions were incorrectly mapped. They were relocated and photographed during aerial photographic surveys of Ross Sea penguin breeding areas on 6 December 1981, 29 November 1982 and 2 December 1983. This paper reports the correct position of each colony, together with detailed description and photograph and an accurate count of occupied nests. Numbers of breeding pairs in 1983 were assessed as Northern Rookery 2,157, Middle Rookery 3,989, Southern Rookery 22,743.
