British Trust for OrnithologyAn organisation founded in 1933 to cater mainly for the serious amateur ornithologist. It is well-known for its co-operative surveys, both those which are repeated each year, such as the Common Birds Census and the nest record scheme, and those relating to a particular period, notably the collection of field data for The Atlas of Breeding Birds in Britain and Ireland, which was published in 1976. The BTO is responsible for the administration of the British ringing scheme and its staff are involved in many fields of ornithological research. It produces the thrice-yearly journal 'Bird Study' which contains scientific papers, the annual publication 'Ringing and Migration' and the bulletin BTO News six times a year. Its headquarters are at Thetford, Norfolk, UK.
