What is new in 2020 data update?
June 30, 2020
In 2020, the set of the European Common Bird Indicators has been produced based on the data for 168 common European species from 28 countries up to 2017, and for the first time the indicators for the year 2018 are estimated using the moving average (running mean).

For the details of the method see Multispecies indicators estimation for the 2020 Indicators Update. This solution has freed up time urgently needed for a deep revision of the whole data set, necessary to enable us to run the new tools in R and implement the new on-line tools correctly.
The smoothed indicators and their lower and upper confidence limits for the periods from 1980–2017 and estimated values for the year 2018 are presented in graphs. All data for the periods till 2018 are available for download in a table (2020 update). Indicators without estimates for 2018, so real data till 2017 are available for download (2019 update), too.
The supranational species indices were not updated in 2020.
Besides this, data quality control and presented species trends and indices until 2017 have not undergone any change, all have been kept consistent with last year’s data update. To see news from 2019 see What is new in 2019 data update?
