About Kees Moeliker
Born 1960. Kees Moeliker is a Dutch biologist, ornithologist and author, known for Necrophilia.
Cornelis W. "Kees" Moeliker (born 9 October 1960) is a Dutch biologist and former curator and director of the Natural History Museum Rotterdam. He is also European Bureau Chief of the Annals of Improbable Research.
Early years Moeliker's father worked for forty years as a technical illustrator for the (subsequently superseded) Dutch post office. Kees himself was provided with education at the Pieter Caland School in Rotterdam. During this time he used to wander across the nature reserves in the Rotterdam area. He graduated with a research project on the winter-season feeding ecology of the Long eared owl (Asio otus). The research later provided the basis for a section in his 1989 compilation, "Owls" ("Uilen"). Moeliker also collaborated on the research led by the high-profile Biology/Ornithology Professor Kees Heij, undertaken at the Free University (Amsterdam) into the population ecology of the House Sparrow (Passer domesticus) in Rotterdam.
Professional career Before he joined the Natural History Museum Rotterdam, Moeliker worked as an assistant-butcher, an English teacher in Istanbul, a nature guide in Costa Rica and a biology teacher at several high schools. A subsequent Moeliker rediscovery, in 2001, involved the Waigeo brush-turkey (Aepypodius bruijnii) he identified in Waigeo Island, Southwest Papua.
Amongst his work for the Natural History Museum Rotterdam, Moeliker preserved the Domino Day 2005 sparrow, a house sparrow that was shot and killed by a hunter after it knocked down a large domino display in Leeuwarden. The bird was stuffed and is now mounted on a box of dominos.
Recognition He won the 2003 Ig Nobel Prize for biology for his study of homosexual necrophilia in male mallards.
He was nominated in 2013 for the Edgar Doncker Prize in recognition of his outstanding contribution to the Rotterdam Natural History Museum and to conservation more generally.
After Moeliker won his Ig Nobel Prize, he earned the nickname of "The Duck Guy". He appears annually at the Ig Nobel Prize ceremony in Boston, Massachusetts, and is a regular performer on the Ig Nobel Prize's tours of the United Kingdom. A Dead Duck Day is held on 5 June every year, "to commemorate the first anniversary of the sudden and dramatic death (on 5 June 1995) of the mallard (Anas platyrhynchos) that entered the scientific literature as the first victim of homosexual necrophilia in this species."
On 6 October 2014, he made a guest appearance on BBC Radio 4 comedy The Museum of Curiosity and donated a single pubic louse to the museum. During the programme the presenter John Lloyd observed that Kees Moeliker did not have an English-language Wikipedia page but only a Dutch-language one. Lloyd went on to state: "We're going to make one about you for the English Wikipedia". Jimmy Wales, the co-founder of Wikipedia, who was also a guest on the programme, replied that that was unnecessary because Wikipedians listen to the show and he predicted that an English-language page for Kees Moeliker would be created before the airing of the programme had finished. Approximately 8 minutes later, and 7 minutes before the programme finished being aired, the first version of this page had been submitted.
