A review of spectacled warbler records was initiated in 1984. This review resulted in the species being removed from the British list; of the three accepted records, one, at Spurn, Yorkshire in 1968, was re-identified as a first-year female subalpine warbler, while descriptions of the other two, at Porthgwarra, Cornwall in October 1969 and on Fair Isle in June 1979, were not considered sufficiently watertight to permit their continued acceptance. Spectacled warbler has since been re-added to the British list following an individual at Filey, Yorkshire in 1992, and there have been further subsequent records. In the late 1990s, BBRC reviewed some of the accepted records of moustached warbler, and concluded that one, from Sussex in 1979, was unacceptable, but that one other, from Buckinghamshire in 1965, should stand. Two further records, from Hampshire in 1951 and Kent in 1952, were reviewed as part of the 1950–1957 review (see below), and found to be unacceptable. Following these rejections, the Buckinghamshire record, and the remaining record, a breeding pair in Cambridgeshire in 1946, previously accepted as Britain's first, were scrutinised by the BOURC and found to be unacceptable, leading to the removal of moustached warbler from the British list; it has not re-occurred.
