UK: Fluctuating with no long-term trend
 
Status Summary
Goldcrest abundance is affected strongly by winter weather and the strong increase in the species' CBC index up to the mid-1970s probably reflects recovery from the cold winters of the early 1960s. The subsequent decline could reflect habitat deterioration in woodland but it should be noted that the CBC does not cover the Goldcrest's preferred habitat of coniferous woodland well. In addition, the long-term trend looks very much like what would be expected of a series of damped oscillations leading to population stability after an earlier perturbation in abundance, so the trend could be driven entirely by the species' internal population dynamics. Recent trends show stability or a shallow increase.
