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.
