Summary

Story summary

A study by the University of St Andrews finds that African penguins forage near commercial fishing vessels during years of low fish abundance.
This overlap intensifies competition for food and contributes to an 80% decline in their population over the past 30 years.
The study introduces 'overlap intensity,' a metric to measure this competition.
In 2016, 20% of penguins foraged near fishing boats, compared with 4% in years with higher fish stocks.
