A forty year study on a remote Antarctic island shows that while populations of two penguin species are declining, a third is increasing. Analysis of census data from Signy Island in the South Orkney Islands reveals that, between 1978 and 2016, the number of chinstrap penguin pairs declined by nearly 70 per cent. Pairs of Adélie penguins dropped by more than 40 per cent but the number of gentoo penguin pairs more than trebled.
