Status summary
Greenfinch abundance varied little up to the mid 1990s, and there was little change in either survival or breeding performance during this period (Siriwardena et al. 1998b, 2000b). More recent CBC/BBS data indicate population increases widely across the UK, followed by a sudden sharp fall induced by a widespread and severe outbreak of trichomonosis that began in 2005 (Robinson et al. 2010). Productivity data are complex, with a substantial reduction in brood size and increased nest survival at the egg stage. Overall, however, there has been no change in the number of fledglings per breeding attempt. The trend towards earlier laying may be explained by recent climate change (Crick & Sparks 1999). There has been widespread shallow increase across Europe since 1980 (PECBMS 2010).
