Abstract:Ringing recoveries are used to investigate the seasonal movements of British Greenfinches. Significantly more females than males make such movements. Outward movement begins by early November and continues until at least late January. The return movement can last from January to May and is particularly rapid in March and early April. The directions of the outward movements are widely dispersed but show trends towards the south and, except in western areas, towards the west. In Britain south of latitude 54°N the proportion of birds leaving their breeding grounds in winter increases from west to east, being negligible in the south-west and largest in East Anglia, but relatively small near the south coast. Distances moved show a similar dependence. The numbers making seasonal movements in a given year are correlated with the breeding population, particularly in south-east England.Ringing recoveries are used to investigate the seasonal movements of British Greenfinches.
