Deadly!

Breached!

Unprecedented trail of destruction!

Scores of Adélie penguins and skuas dead!

and what percentage is that of the entire Adélie penguin and skuas populations?

I will tell you.

Because of its very large and increasing population (estimated at more than 10 million mature individuals in 2020), and its unfragmented habitat, the Adélie penguin is considered by the International Union for Conservation of Nature to be a species of least concern.

How is that a "mass mortality event"

Look out Australia the bird flu jab is heading your way.
