PENRYN, United Kingdom (Reuters) – The African penguin joins the list of species said to be threatened by climate change – and overfishing.

Researchers from the United Kingdom and South Africa say penguin numbers in the Benguela upwelling ecosystem have halved in just 30 years.

The sardines and anchovies they feed on have moved eastwards, due to changes in water temperature and salinity.

Scientists tagged juvenile penguins and found them traveling fruitlessly to their old hunting ground, caught in a so-called ecological trap.
