Macaroni penguin been considered separate species, but the close similarities of their DNA sequences has led some, such as the Australian ornithologists Les Christidis and Walter Boles, to treat the royal as a subspecies of the macaroni. The two species are very similar in appearance; the royal penguin has a white face instead of the usually black face of the macaroni. Interbreeding with the Indo-Pacific subspecies of the southern rockhopper penguin ("E. chrysocome filholi") has been reported at Heard and Marion Islands, with three hybrids recorded there by a 1987–88 Australian National Antarctic Research Expedition. The macaroni penguin is a large, crested
Macaroni (horse) hour, owing to a record thirty-two false starts caused by horses breaking away or failing to line up correctly. The huge field led to good deal of bumping and roughness, with three horses either falling or being brought down. Chaloner held up Macaroni in the early stages, before moving into fifth place entering the straight. A furlong from the finish, Lord Clifden went into a clear lead and looked the likely winner, but Macaroni produced a strong late run to catch the favourite in the last strides and win by a head. Rapid Rhone finished well to take third place.
