iNaturalist has a number of settings related to common names, and they are applied in a particular way. This is how iNat determines the common name displayed to you:
- First, iNat looks for the default (top-ranked) name that is set to be used in your preferred name place
- If you have no place priority set, or there is no name listed for that place, then iNat will use the top-ranked name in your Language/Locale setting
- If there is no name listed for your Language, then iNat will use the top-ranked Global Name
Additional notes: when checking for names in your preferred name place, iNat will also check ancestor places, but only if your Language setting matches the language of the common name. For example, if your preferred place is set to Wien, which is a child of Austria, you will see the name for Austria if you are running the site in German.
The languages available in the Language/Locale setting are determined by their site translation status.
Only curators have access to the page that shows the name rankings and place associations, however anyone can use the API to view this information, e.g. https://www.inaturalist.org/taxon_names.json?taxon_id=55819.
If you still aren’t sure why a particular common name is displayed for you, please add a post including your Language/Locale setting, your preferred place name setting, the taxon, the name you are seeing, and the name you expect to see.
