Ebby and Peru are now rarely seen apart at Colchester Zoo, where their new bond has grown.
Ebby, aged 19, arrived from Germany in 2007 as a juvenile. She formed close bonds with several partners, including Mako, before he died this year. She can be recognised by the large black mark on her tummy.
Peru, aged 13, joined the zoo from the Czech Republic in 2014, also as a juvenile. He had previously shared his life with Tequila, who also died this year.
A statement on the Colchester Zoo website said: “For Humboldt Penguins these relationships can be particularly important.
“They are known for forming strong, long-lasting bonds and often remain with the same partner for many years.
“However, when a partner dies or does not return, they can go on to form a new pairing.
“What started as a companionship has since developed into something more.
“They have now formed strong bonds.”
Zookeepers say the pair enjoy spending time together among the bamboo or in their nest box.
Visitors can look for the pair along the Inca Trail. They may see the penguins tucked away together, exploring their surroundings or sitting side by side.
The zoo said Ebby is one of the easiest penguins to spot because of the mark on her tummy. These days, wherever you find Ebby, there’s a good chance that Peru is close by.
Visitors can watch their relationship develop first hand at the zoo.
