Albatrosses cannot recognise their chicks by sight, sound, or smell – they only know them when they're in the nest.
The albatross population on Bird Island is facing extinction because of climate change. Vicious storms knock chicks out of the nest and they can freeze to death on the ground. Unfortunately, since their parents don't recognise them out of the nest, they don't help them and albatross chicks must climb back in by themselves to live, which is not always achievable.
