"According to the IUCN Red List criteria, a species is generally classified as Endangered (EN) if its population of mature individuals falls below 2,500"
Also IUCN, with only 180,000 individuals the Emperor penguin is now classified as Endangered.
I think someone has been out hunting headlines.
That is objectively a wrong summary of how IUCN Red List is calculated. There’s a variety of factors including rate of decline, and any of those factors can lead to a species being in the Endangered category.
