The 2020 CES season should have been from the 30th April until the 2nd of September. However, due to imposed Covid restrictions the first visit was actually on the 14th June.
The birds per session figure was 82.25 calculated by dividing the total of each session's catch by the number of visits,8. This figure compares to 85.75 from 2019 and 67.0 in 2018.
During 2020 there was a distinct lack of juveniles of resident species. Migrant species juveniles were near or slightly better than in normal years.
Blackcap were down after the exceptional influx of numbers during August of last year. Reed Warblers suffered from the reedbed water level being low throughout the summer, affecting nesting and feeding opportunities resulting in a lower than average catch.
In summary, 2020 CES shows it to have been an average year.
