Migration patterns of two populations of twite carduelis flavirostris in Britain
2006
Following a recent large decline in range and numbers, the Twite Carduelis flavirostris is a red‐listed bird of conservation concern. An understanding of the species’ movements between wintering and breeding areas is essential to underpin effective conservation. The migration patterns of two populations of Twite were examined: those breeding in the South Pennines and those wintering on the west coast of Lancashire and Cumbria. This was achieved by carrying out an intensive colour‐ringing study on the two populations between 2003 and 2005. Birds breeding in the South Pennines wintered predominantly on the east and southeast coasts of England. However, a small number migrated to the west coast of England. Furthermore, large flocks of predominantly South Pennines‐bred individuals overwintered in the South Pennines. From the single previous recovery, northwest‐coast birds were also thought to originate from the South Pennines. However, resightings from this study suggest that these birds breed primarily on th...
