Sir Frank Fraser Darling FRSE (23 June 1903 – 22 October 1979) was an English ecologist, ornithologist, farmer, conservationist and author, who is strongly associated with the highlands and islands of Scotland. He gives his name to the Fraser Darling effect.
Early life
Fraser Darling was born in Soresby Street in Chesterfield in northern England, the illegitimate son of Harriet Cowley Ellse Darling and Cpt. Frank Moss.
His mother was the daughter of a prosperous family from Sheffield. Her family wanted the child to be fostered and forgotten about. However, she would not cooperate and refused to part with Frank. His father, whom he never met, left for East Africa around the time of his birth, and was killed in action on the Kenya-Tanganyika border in 1917.
In 1966, Darling revealed to his son that the pioneering plant geographer, Charles Edward Moss, was his uncle.
Career
After running away from school at the age of 15, Darling was sent to work on a farm in the Pennines. He then studied at the Midland Agricultural College (now part of the University of Nottingham), at Sutton Bonington in the Borough of Rushcliffe in Nottinghamshire, and obtained diplomas in agriculture and dairying. Soon afterwards he married Marion Fraser ("Bobbie") and took the double-barrelled surname Fraser Darling, which, although he was divorced from Bobbie in 1948, he used until the end of his life.
While working as a Clean Milk Advisor in Buckinghamshire, and longing for a research post in Scotland, Fraser Darling heard about the work of the Institute of Animal Genetics at Edinburgh University, and in the early 1930s the Director, Francis Albert Eley Crew, offered him a place there to study for a PhD. From 1929–1930 he was Director of the Commonwealth Bureau of Animal Breeding and Genetics, part of the Commonwealth Agricultural Bureaux, at Edinburgh.
In 1934, he was elected a Fellow of the Royal Society of Edinburgh. His proposers included Francis Albert Eley Crew, William Christopher Miller, and A. D. Buchanan Smith.
Living at Dundonnell and later in the Summer Isles, Fraser Darling began the work that was to mark him as a naturalist-philosopher of original turn of mind and great intellectual drive. He described the social and breeding behaviour of the red deer, gulls, and the grey seal respectively, in the three academic works A Herd of Red Deer, Bird Flocks and the Breeding Cycle and A Naturalist on Rona. The Fraser Darling effect, proposed by Fraser Darling in 1938, is the simultaneous and shortened breeding season that occurs in large colonies of birds.
The outbreak of the Second World War put an end to Fraser Darling's hopes of undertaking further research on the grey seal and, being too old for active military service, he chose to farm rather than leave the west coast of Scotland for wartime civilian work. Between 1939 and 1943 Fraser Darling reclaimed derelict land to agricultural production on Tanera Mòr in the Summer Isles. In 1942, the wartime Secretary of State for Scotland, Thomas Johnston, asked him to run an agricultural advisory programme in the crofting areas of the Scottish Highlands and Islands. He agreed, and for two years he travelled, taught and wrote articles that were later published in book form as Crofting Agriculture. In 1944 he was appointed as Director of the West Highland Survey based at Kilcamb Lodge on the Strontian Estate in Ardnamurchan
