John Michael Cullen

John Michael Cullen (14 December 1927 – 23 March 2001) was an Australian ornithologist, of English origin. Mike Cullen began his academic career by studying mathematics at Wadham College, Oxford, but later switched to zoology, spending time at the Edward Grey Institute of Field Ornithology while investigating the ecology of marsh tits. He subsequently achieved his PhD with Niko Tinbergen with a study of the behaviour of the common tern on the Farne Islands off the coast of Northumberland.

In 1976 he moved to Australia, to Monash University in Melbourne, Victoria. There he was involved in an investigation of Abbott's booby on Christmas Island which was threatened by phosphate mining. He served on the Field Investigation Committee of the Royal Australasian Ornithologists Union (RAOU) for which he organised the Rolling Bird Survey project. However, he is best known for long-term studies of the little penguin at Phillip Island and in Port Phillip Bay at St Kilda, in collaboration with Pauline Reilly and others.
