Report on bird‐ringing for 1987

Abstract

This is the 50th report issued on behalf of the Ringing Committee of the British Trust for Ornithology. The report summarises the numbers of the birds ringed during I986 and the recoveries reported during that year — including full details for selected records. Totals of recoveries of British and Irish-ringed birds in each country outside Britain and Ireland and of the number of birds ringed in each country elsewhere and subsequently recovered in Britain and Ireland are given for each species. These totals are given for the five year period 1982-1986 and grand totals of records up to the end of 1986, and form part of a series of such summaries produced every five years. The report draws attention to particularly interesting records and to some of the factors which have influenced the BTO Ringing Scheme and its results during 1986.
