Wotsit broke out of its egg on Easter Sunday, quickly followed by Quaver (Sunday) and Frazzle (Monday), with Cheeto arriving just this morning weighing a mere 75g. The tiny youngsters – threatened Humboldt penguins from South America – have been named after their keepers’ favourite crisps.
Our keepers use a different naming theme each year to help them to keep track of the new chicks, with popular potato snacks getting the nod this time around. Previous topics have included British Olympic athletes, chocolate bars and even the keepers’ favourite curries.
Both penguin parents are involved in the rearing of the chicks and it will now be around eight weeks until the juveniles leave the nest. Until then, keepers will be carefully carrying out daily checks on their weight gain and development.
Keeper Anne Morris, said:
With more mouths to feed, more food is required and so we’re providing the parents extra fish so that they can keep the little ones well fed. It’s quite a messy business as the adults churn the fish into a high-protein soup which they then regurgitate up for their chicks.
It’s vital that chicks take on-board enough nourishment each and every day in these early stages and so, in order to keep a close eye on their development, we weigh them on our tiny set of scales. So far, our new arrivals are doing very, very well and so they won’t stay so small for long. In the next few weeks we expect them to more than triple in size and weight!
Humboldt penguins live on the coastal areas 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.
We fund conservation initiatives in South America, where the species is threatened by climate change, rising acidity levels in the ocean and over-fishing – all of which is forcing them to search further from their nests for fish.
Humboldt penguins are becoming increasingly rare. Of the world’s 17 penguin species, they are now among the most at risk, so it’s very important to us that our tiny arrivals create more awareness for these amazing birds. We’ve been very successful with this colony over the years and will yet again be making another vital contribution to the European breeding programme for the vulnerable species.
Just so you know…
If you’re planning a visit please bear in mind that as the chicks have just hatched it will be around eight weeks until they leave the nest.
Humboldt penguin facts
- The first Humboldt penguin chick (Wotsit) hatched on 27 March 2016, the second (Quaver) on 3 April 2016, the third chick (Frazzle) arrived on 4 April 2016 and Cheeto arrived today (Tuesday 5 April 2016).
- Scientific name: Spheniscus humboldti
- This South American penguin is named after the chilly Humboldt current, along which the penguins commonly swim
- In the wild, Humboldt penguins are vulnerable to disturbances in their food chain caused by strong El Nino currents
- Humboldt penguins are social animals, living in relatively large colonies of closely spaced burrows
- Humboldt penguins ‘fly’ through the water at speeds of up to 25mph
- They enjoy a diet of small fish (anchovies, herring, smelt) and crustaceans
