IF I use the tags I often have the "alternative" or old names for the species there. For example, if I would upload a photo of a Silver-beaked tanager (Ramphocelus carbo), I potentially would then tag the photo with Maroon tanager, Silver-billed tanager, and Lanius carbo - synonyms/alternative names for that species. While keeping one of the most recent/"correct" names in the title.
And sometimes I also add the species name in some other languages, like for example German and French.
