You can summarize iNat observations with a filter, like so:
https://www.inaturalist.org/observations?verifiable=any&taxon_id=683312 **
to get the taxon_id number, merely go to the taxon page: it is the number in the url:
https://www.inaturalist.org/taxa/683312-Philoliche-lateralis
(** note this defaults to your default place: specify a place if it is important to have a specific area, e.g.: Africa &place_id=97392).
Thanks @tonyrebelo, I do put up links only for observations I have reviewed and where I am certain of correct identification.
Maybe I should include one (or two for male and female) iNat photo together with the link in order to facilitate quick identification. Do I have to ask permission from the observer for this or can I use the photo on an iNat journal post without checking copyright? What do you think?
Like this:
Always check copyright on the photo (not the observation). For my observations/photos you are always welcome anytime.
For others, it is polite to ask the first time (and ask for general use, and provide a link to your project). But if they are strictly copyright (and often watermarked) then you do need "written" permission for every photo.
