Ian Newton(born 17 January 1940) is an English ornithologist.
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.
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 Birdsand 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).
The Eurasian sparrowhawk, also known as the northern sparrowhawk or simply the sparrowhawk, is a small bird of prey in the family Accipitridae. Adult male Eurasian sparrowhawks have bluish grey upperparts and orange-barred underparts; females and juveniles are brown above with brown barring below. The female is up to 25% larger than the male – one of the greatest size differences between the sexes in any bird species. Though it is a predator which specialises in catching woodland birds, the Eurasian sparrowhawk can be found in any habitat and often hunts garden birds in towns and cities. Males tend to take smaller birds, including tits, finches, and sparrows; females catch primarily thrushes and starlings, but are capable of killing birds weighing 500 g (18 oz) or more.
The European rock pipit, or just rock pipit, is a species of small passerine bird that breeds in western Europe on rocky coasts. It has streaked greyish-brown upperparts and buff underparts, and is similar in appearance to other European pipits. There are three subspecies, of which only the Fennoscandian form is migratory, wintering in shoreline habitats further south in Europe. The European rock pipit is territorial at least in the breeding season, and year-round where it is resident. Males will sometimes enter an adjacent territory to assist the resident in repelling an intruder, behaviour only otherwise known from the African fiddler crab.
