Status summary
The UK Bullfinch population has been in decline since the mid 1970s, following a period of relative stability. The decline was initially very steep, but has been shallower since the early 1980s. Nevertheless, the CES and CBC/BBS both suggest that the decline is continuing, at least in southern Britain. The demographic mechanism remains unclear (Siriwardena et al. 1999, 2000b), although agricultural intensification is suspected to have played a part. CES data indicate that productivity may have increased over the last decade. However, nest failure rates at the egg stage have risen through the 1990s.
