SHORT COMMUNICATIONS EMU 90 Hybrid Rockhopper-Macaroni Penguins, Interbreeding and Mixed Species Pairs at Heard and Marion Islands
The genus Eudyptes consists of six species distributed throughout the subantarctic islands and the Antarctic Peninsula (Watson et a1 1971). At many of the breeding localities species are sympatric (Warham 1975). There has been one published report of mixed species pair of Eudyptes penguins breeding,...

Summary: | The genus Eudyptes consists of six species distributed throughout the subantarctic islands and the Antarctic Peninsula (Watson et a1 1971). At many of the breeding localities species are sympatric (Warham 1975). There has been one published report of mixed species pair of Eudyptes penguins breeding, that of an Erect-crested E sclaten-Rockhopper Penguin E chrysocome pair on West Point Island in the Falkland Islands (South Atlantic Ocean) between 1961 and 1966 (Napier 1968). The only account of a hybrid eudyptid penguin was reported by Simpson (1985), who documented a Rock-hopper x Royal Penguin E schlegeli hybrid collected at Macquarie Island in 1957. Simpson (1985) also reported an Erect-crested-Royal Penguin pair during the moult period following the breeding season at Macquarie Island in January 1964. We present details of three Rockhopper x Macaroni Penguin (E chrysolophus) hybrids from Heard and R h i o n Islands. |
