Of 17 known penguin species in the world, Humboldt penguins are becoming increasingly rare and now are listed as vulnerable to extinction, according to the International Union for the Conservation of Nature (IUCN).
Therefore, Chester Zoo, which is one of the UK’s most active institutions in the captive breeding of endangered species, got really excited when this year as many as 11 Humboldt penguin chicks successfully made it through the first 40 days of life.
