Senior birds keeper Christopher Kent said: “We don’t yet know the sex of the chick. The penguins have been using nesting materials and guano (seabird droppings), as they would in the wild, to make their nests.
“We are very much ‘hands off’ with bird rearing and only intervene where absolutely necessary. Echo and Lilly are both experienced parents and they are doing a fantastic job.
“Both parents will take turns to incubate the eggs for around 40 days and care for their young once hatched. The chick is fed regurgitated fish by its parents.”
Humboldt penguins are found along the coasts of Peru and Chile and are listed as vulnerable to extinction on the International Union for the Conservation of Nature’s (IUCN) Red List of Threatened Species.
