Extremely common, with an estimated population of over 18 million, Macaroni Penguins face issues with population decline in some areas.

Their large numbers don't fully protect them from threats such as overfishing, which depletes their main food sources, and climate change.

Changing ocean currents and warming waters impact their food supply, leading to decreased breeding success.

Macaroni Penguins get their name from the crest of yellow feathers, which 18th-century English sailors thought resembled the fashionable "macaroni" wigs of the time.
