· Species presence to see the proportion of lists that registered the selected species on a specified geographical area.
· Presence comparison by area to compare the presence of selected species between two geographical areas.
· Presence comparison by year to compare the presence of selected species between two years.

Species presence

Percentage of submitted lists at the geographical area selected that contains at least one observation of the selected species.

1. Check/Uncheck to select times to show. 2. Place pointer on current year to see the percentage of lists containing the selected species for a specific date.   Legend The data compares the current year, the previous year, and the average of ten years; but not the average of 5 years.   Date On 21th February (current year) 11.11 % of submitted lists recorded the selected species.   September data By mid September, just over 60 % of submitted lists during the last 10 years recorded the selected species, while almost 80 % of lists submitted last year contained the species.

Presence comparison (by area)

Percentage of submitted lists in the two selected geographical areas that contain the selected species.

Species

Returns a list of all species recorded and its numbers in descending order (see image Confinement stats: Species). Choose the taxonomic group you want to visualise from the expandable menu. The returning list indicates the number of records for each species, and the number of lists including the species both in aboslute and relative numbers. In the given example (see image Confinement stats: Species), House Sparrows were recorded a total of 4698 times in tht ornitho.cat portal, 3845 of these records were part of one of the 4629 total lists recorded. Therefore, House Sparrows were recorded in 83 % of lists submitted.

Observers

A graph on top represents the number of active observers during each day of confinement. Underneath, observers are listed along with their corresponding number of records, lists and hours of observation. Those contributing higher number of lists are on top. On the example below (see image Confinement stats: Observers), the observer contributing the most lists, their name hidden, recorded a total of 3975 observations of 65 different species belonging to 348 lists during over 6h of observation.
