Christopher Miles Perrins, LVO, FRS (born 11 May 1935) is Emeritus Fellow of the Edward Grey Institute of Field Ornithology at the University of Oxford, Emeritus Fellow at Wolfson College, Oxford and Her Majesty's Warden of the Swans since 1993.
Perrins was educated at Charterhouse School and Queen Mary College where he was awarded a Bachelor of Science degree in Zoology in 1957. He completed his postgraduate study and research at the University of Oxford where he was awarded a Doctor of Philosophy degree in 1963 for research on brood size in tits supervised by David Lack.
Research and career
Perrins research interests are in the population dynamics and breeding biology of birds, particularly tits (Paridae), mute swans and seabirds on Skomer and Skokholm. He investigated animal lead poisoning of swans from lead shot. He is renowned for his work on avian population ecology and, in particular, reproductive rates. He has made a number of important contributions to the long-term study of the great tit at Wytham Woods — an area of mixed woodland established in 1947 by evolutionary biologist David Lack — one of the most famous studies in population ecology.
He was the first to discover that avian clutch size — the number of eggs laid in a single nesting — in great tits has a remarkably high heritability and that the likelihood of the survival of young birds can be traced back to nutrition in the nest. Perrins also demonstrated that females lay a clutch of an appropriate size for their ability to feed. He supervised several successful DPhil students at Oxford including Matt Ridley.
