To jump straight to a particular species, find the species in the table of trends, and click on the 'graph' link. You will be taken back to this page, with the relevant species graph at the top.
On each graph, the red line is the smoothed trend, the blue line is the unsmoothed trend, and the green lines are the upper and lower 95% confidence limits of the smoothed trend.
These graphs may be reproduced, subject to the appropriate acknowledgement of the BTO/JNCC/RSPB Breeding Bird Survey. Spreadsheets containing the data points for each graph may be obtained by emailing bbs [at] bto [dot] org.
