A number of layout changes and adjustments are needed for the popup. This includes:
Add country and show landscape/province fields, if country is Sweden, show only the landscape, else show the land and the locations, remove parentheses around locations (because usage of parenthesis indicates "not found but given" and shouldn't be used unless present in source data)
Replace NA values with empty strings
Image of the bird, linked to other resource with more information about the species or its population trends
The popup text "Märkdatum:" should be "Märkt:" / "Ringed:"
The popup text "Fyndests datum: " should be "Funnen: " / "Recovered: "
Add "Fyndets År" and "Fyndets Månad" in the simple UI
In English we prefer using "Species" instead of "Vernacular" in both selection fields and popup.
Countries should be sorted alphabetic.
In Swedish the months should have Swedish names.
Impossible to use scroll bars with mouse to select species, year etc.
Remove "Source" field in simple UI.
Add info about current selection (perhaps in empty space top right above map) as "Robin - 4000 latest recoveries of 13 456", or if no species selected "All species - 4000 latest recoveries".
Perhaps we could have the possibility to add one source code in a special url for use to display the data for one selected ringer/bird observatory. (can wait some time)
