Status summary
Lesser Redpolls were abundant and widespread in lowland Britain in the 1970s, and frequent on CBC and CES plots, but are largely absent now as breeding birds after a sustained period of severe decline. Uncertainty about the representativeness of the monitoring data prior to the establishment of BBS once denied the species a place on the red list, since it was thought possible that the population may have withdrawn from the lowlands to northern and western UK regions, where monitoring prior to 1994 was less effective. No evidence for such a shift exists, however: the species was moved from green to amber in 2002 and now to red. The 1988–91 Atlas showed a range contraction of 11% since 1968–72, which is evident in all parts of the UK (Gibbons et al. 1993). In southern Britain, at least, decrease may be attributable to a reduction in the amount of suitable young forest growth (Fuller et al. 2005). Though samples are too small to continue presenting a trend, CES data indicated a rapid long-term decline in productivity, and there is evidence that survival rates have also fallen (Siriwardena et al. 1998a). Since C. cabaret is now widely treated as a separate species from the Common Redpoll C. flammea, and has a restricted range that lies wholly within western Europe, it is likely to gain a European conservation listing at the next review. A strong increase has been recorded in the Republic of Ireland since 1998, however (Crowe et al. 2010).
