Most important issue is the lack of common names in iNaturalist in the correct language. But when it comes other locales there are many little issues, like Wikipedia.
When you look at the wikipedia information on this page in an other languague then english https://www.inaturalist.org/taxa/145308-Spinus-psaltria the hyperlinks in this article refer to the english wikipedia. I should expect it would link to the same wikipedia as the original article.
( If I get a message ‘your topic is similar to’ should I add this topic it to that topic, whichs also has Wikipedia as topic ]?
