The reason is the opposite of what I was expecting to hear.
All but two Adelie penguin chicks have starved to death in their east Antarctic colony, in a breeding season described as “catastrophic” by experts.
It was caused by unusually high amounts of ice late in the season, meaning adults had to travel further for food.
It is the second bad season in five years after no chicks survived in 2015.
Oh well. Darwin is proven right again for the thousandth time.
