climate than the more southerly Falklands. On Marion, Rand (1955,
p. 61-63) estimated 52 000 King penguins nesting on raised pebbly
beaches, but only about 500 Gentoos among tussock grass nearby.
Rockhoppers were reported as fairly numerous on grass-covered cliffs,
scree and boulders; rather surprisingly the most plentiful penguin seems
to be the Macaroni (“in vast numbers”, Crawford and Serventy, 1952,
