This report presents an updated population trends and indices of 170 common European bird species for the time period 1980-2016 that have been produced by the Pan-European Common Bird Monitoring Scheme (PECBMS) in 2018. The species trends presented are for long time period (from 1980 onwards until 2016) and for last ten years (2007-2016).

In 2018, reliable European index was produced on 170 species, which is the same number of species as in the last update in 2017.
Altogether 28 countries provided their data for this update: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Republic of Ireland, Romania, Slovenia, Slovakia, Spain, Sweden, Switzerland, United Kingdom.
The countries provided the data for different time periods, see Methods, chapter 2. Supranational species indices and trends or check the ´List of countries´ at the individual species graphs.
Detailed description of computation steps and methods is available in special section Methods, in chapter 1. National species indices and trends and chapter 2. Supranational species indices and trends.
Species habitat classification for main habitat types (farmland, forest and other) is described in Methods, chapter 3, Box Species selection and classification.
We present long-term and ten-year trends and slopes in the table. The Long-term Slope is calculated over the period 1980-2016 but starting years of this long time period vary from 1980 to 1998 (as specified in the Species notes below the table of trends). In parallel, the Long-term Trend represents a change (in %) in an index value between the first and the last year of this long time period. The Ten-year Slope is calculated over the period of last ten years, i.e. 2007–2016. Similarly, Ten-year Trend represents a change (in %) in an index value between the first and the last year of the period of last ten years.
Updated European species indices, long-term and ten-year trends and slopes, and species habitat classification are summarized in the table. For explanations to the table see also the pop-up windows which appear after clicking on the notes shown in selected species names as upper index.
To generate graph for the selected species, tick the check box at left side of species name and click Show button above the table to confirm and proceed your selection. You can draw graphs for several selected species in separate graphs or at once in one graph – select the option in All data in one graph above the table. If you wish to Show confidential limits, you may choose this option only in case that you selected only one species to be shown in a graph. You can also quickly deselect your choice (Reset). The list of countries and time periods for which the countries provided the data can be found at individual species graphs (Countries). You can choose to order species trends by alphabet or by taxonomic classification, see Order button in the head of the table and select alphabet or taxonomy.
