While their fellow penguins prepare for breeding season , the pair only have eyes for each other as they get ready to celebrate their first anniversary this month . Happy anniversary ! Peso ( right ) and Squaddle ( left ) got together after shunning females looking to mate . Two 's company ! Zoo staff had given the couple a false egg during breeding season , but they threw it away . Staff at Folly Farm say the young lovers have no interest in procreating . They had been given a false egg , so that they would n't feel left out during breeding season - but they threw it out of their love nest . Penguin keeper Catrin Thomas said : 'We 're approaching breeding season and at around two years old , penguins become sexually mature , so we thought this year they may show some interest but they have n't as yet . 'All the other penguins are busy making nests at the top of the penguin beach , scrambling around hurriedly and gathering twigs , but Peso and Squaddle stay by the pool preening each other . ' Penguin posers : The Humboldts , who live at Folly Farm , Pembrokeshire , are celebrating their first anniversary . They only have eyes for each other ! The pair have no interest in procreating and threw the egg of their nest . She added : 'Peso and Squaddle do n't seem to be interested in anything else but each other , and certainly not procreating . 'They 're just enjoying each other 's company . ' Tim Morphew , Folly Farm 's zoo manager , said : 'We wanted to mark the occasion and the year anniversary of Peso and Squaddle getting together . 'Everybody who comes to Folly Farm says theirs is a really sweet love story and we wanted to celebrate the fact they were still going strong a year on . ' Humboltd penguins , who are monogamous and mate for life , can take a partner aged between two and eight-years-old . Penguins have been observed engaging in homosexual behaviour from as early as 1911 . George Murray Levick documented the sexual behaviour of Adélie penguins in Antarctica , but his notes were considered too indecent to publish at the time . They were rediscovered and published in the journal Polar Record a century later in 2012 . More recently , a pair of chinstrap penguins called Roy and Silo became a famous 'gay penguin ' couple after the New York Times published an article about them in 2004 . The penguins , who live in New York 's Central Park Zoo , were noticed performing mating rituals in 1998 , by staff - although they were never seen to perform sex acts . They were then given an egg to hatch and raise as their own - a practice copied by zoos across the world . Their chick , named Tango , grew up to form a same sex relationship with another female penguin . Their story was the basis for a controversial children 's book in 2005 called 'And Tango Makes Three ' . But the couple later split , and Silo paired with a female penguin . Last year , a pair of Humboldt penguins , called Jumbs and Kermit , from Wingham Wildlife Park in Kent , adopted the chick of a female called Isobel who had to abandon her egg to find food . Staff at Wingham Wildlife Park said they were the two ‘ best penguin parents ’ the zoo has ever had . But a French study in 2010 said penguins only have gay 'flings ' because they are lonely , but ultimately end up in a heterosexual couple .
