SUB-ANTARCTIC – King penguin colonies in Crozet, Kerguelen and Marion sub-Antarctic islands – more than 70% of the global king penguin population – may be nothing more than a memory in a matter of decades, as global warming will force the birds to move south, or disappear. This is the conclusion of a study carried out by an international team of researchers and published in the journal Nature Climate Change.
"The main issue is that there is only a handful of islands in the Southern Ocean and not all of them are suitable to sustain large breeding colonies" said Robin Cristofari, lead author of the study, from the Institut Pluridisciplinaire Hubert Curien (IPHC) (a mixed research unit of the CNRS and the University of Strasbourg) and the Centre Scientifique de Monaco (CSM).
King penguins are picky animals – in order to form a colony where they can mate, lay eggs and rear chicks over a year, they need tolerable temperatures all year round, no winter sea ice around the island, and smooth beach of sand or pebbles. But, above all, they need an abundant and reliable food source close by to feed their chicks.
