Yes, I think it would be worth adding a cautionary sub-bullet under #1, to look for multiple photos first, and if they are not the same species, leave a comment instead of an ID (with some suggested boilerplate wording). What do others think?
For any who haven’t seen it yet, there is also a separate discussion on this issue: https://forum.inaturalist.org/t/easy-way-to-flag-multiple-species-observations/278
EDIT: some suggested boilerplate language for this situation can be found here:

EDIT: Wiki updated, see under #7.
