Education and early life
Newton was born and raised in north Derbyshire and was educated at Chesterfield Grammar School. He graduated from the University of Bristol. He received his D.Phil. in 1964 and D.Sc. in 1982 from the University of Oxford, and has studied a wide range of bird species.
Career and research
He has been interested in birds since his childhood. As a teenager he became particularly fascinated by finches and undertook doctoral and post-doctoral studies on them. Newton conducted a 27-year study of a Eurasian sparrowhawk population nesting in southern Scotland, which resulted in what many consider to be the most detailed and longest-running study of any population of birds of prey.
Before retirement, he was Senior Ornithologist at the United Kingdom's Natural Environment Research Council. He has also been head of the Avian Biology Section at the Monks Wood Research Station (1989–2000), Chairman of the Board of The Peregrine Fund, Chairman of the Council of the Royal Society for the Protection of Birds and visiting professor of ornithology at the University of Oxford. Newton has also held the positions of President of the British Ornithologists' Union and the British Ecological Society (1994–1995).
