Pasteurella multocida infections in rockhopper penguins (Eudypteschrysocome) from Campbell Island, New Zealand
During an investigation into the population decline of rockhopper penguins (Eudypteschrysocome) on Campbell Island, New Zealand, avian cholera (Pasteurella multocida) was found in dead adults and chicks.
Rockhopper penguins, Eudyptes crestatus (Vieillot, 1816), include 3 distinct subspecies: the Southern, Eudypteschrysocomechrysocome, Eastern, Eudypteschrysocome filholi, and Northern, Eudypteschrysocome moseleyi, Rockhoppers.
They are among the smallest of the world's penguins averaging 52 cm in length and 3 kg in weight.
Rockhopper penguins, Eudyptes crestatus, are opportunistic feeders and feed on crustaceans (including Euphausia lucens, E. vallentini, Thysanoessa gregaria and Themisto sp.
A study of the Rockhopper Penguin (Eudypteschrysocome) in 1960 and 1961 was based mainly on observations of banded breeders.
Here the large colonies of Rockhopper Penguins (Eudypteschrysocome) are mainly found on the rocky west coast.
Be- cause these colonies adjoin and to some extent intermingle with those of the Royal Penguin (Eudyptes chrysolophus schlegeli) and because of their location amid talus debris, it is not possible to estimate the island's total Rockhopper population, but it must be of the order of some hundreds of thousands of birds.
These are the King Penguin (Aptenodytes patagonicus), Gentoo Penguin (Pygoscelis papua), Rockhopper Penguin (Eudypteschrysocomechrysocome), Macaroni Penguin (Eudyptes chrysolophus) and Magellanic Penguin (Spheniscus magellanicus).
The Falkland Islands and South America are home to two species of the Genus Eudyptes; the Southern Rockhopper and the Macaroni (Bingham in 1998b).
The 1996/97 aerial census was conducted throughout the known Eudyptes breeding ranges of Chile and Tierra del Fuego (Woehler 1993).

They are found on islands near the Antarctic polar front to those near the subtropical convergence in the South Atlantic and Indian Oceans.
There are three sub species, all recorded in the New Zealand region; western rockhopper, chrysocome and Moseley’s rockhopper moseleyi; the eastern rockhoppers, filholi, breed on the Antipodes, Auckland and Campbell Islands.
Academy of Natural Sciences, 19th and the Parkway, Philadelphia, Pennsylvania 19103 USA An adult male Rockhopper Penquin (Eudypteschrysocome) with a broken wing was collected on Cormorant Island near Palmer Station, off the south coast of Anvers Island, Antarctic Penninsula (64ø8'S, 63ø58'W) on 29 December 1980.
The facial characteristics and head plumes were consistent with the dark- faced form (chrysocome) expected for a bird from South America or the Falkland Islands (Carins 1974), although the underwing pattern was more like that of the subtropical form moseleyi (Prevost and Moughlin 1970).

Penguins are perhaps among the best-known birds on Earth, although ironically at first glance they scarcely seem to belong to that class.
The crested penguins (genus Eudyptes), such as the rockhopper and macaroni, are distinguished by orange or yellow feather crests on the sides of the head, above the eyes.
DECREASE IN NUMBERS OF THE EASTERN ROCKHOPPER PENGUIN EUDYPTESCHRYSOCOME FILHOLI AT MARION ISLAND, 1994/95—2002/03
The number of eastern rockhopper penguins Eudypteschrysocome filholi breeding at subantarctic Marion Island decreased from about 173 000 pairs in 1994/95 to about 67 000 pairs in 2001/02.
During 1994/95—2002/03 pairs fledged on average 0.40 chicks per year, an amount thought insufficient to balance mortality of breeding adults, and there was a decrease in the mass at arrival at breeding colonies of both males and females.
