Scotland trends
• Trends are percentage changes in bird populations, and are marked with an asterisk (*) where the 95% confidence limits of the change do not overlap zero (indicating that there has been a significant change).
• The trend since the start of the survey, covering the years 1994–2010, has been smoothed, and the end years truncated. This trend is labelled as 1995–2009.
• The sample is the mean number of squares per year on which the species was recorded during 1994–2010.
• LCL and UCL are the lower and upper 95% confidence limits for the 1995–2009 trend.
• Red-listed and amber-listed species from ‘Birds of Conservation Concern 3’ are shown in the relevant colour.
• Trends for species in brackets are reported with caveats.
