Status summary
Like those of Song Thrush and Blackbird, Mistle Thrush populations have declined significantly since the mid 1970s, especially on farmland. The species was recently moved from the green to the amber list because of population decline, and recent BBS data suggest that this decline is continuing. The Scottish BBS trend, in contrast to those elsewhere in the UK, is of strong increase since the late 1990s. There has been linear increase in the number of fledglings per breeding attempt, and a minor increase in clutch size; population decline is thus likely to have been driven by reduced annual survival (Siriwardena et al. 1998). Numbers have fallen widely in Europe since 1980 (PECBMS 2010).
