Compare lists with Result a table

You need to fill out three queries, one for each user name and a third one including all observations.
To enter the correct string for each query, go to the explore tab. Then, filter for the required fields (taxon, user name) and copy+paste everything of the URL after the ‘?’ into the first query field.
Then replace the user name in the next query and remove that part for the third query.

You will find that 9 species are ‘unique’, i.e. neither seen by you nor by your colleague

I did some experimentation. Yes, &unobserved_by_user_id= works, and yes, it does support comma-separated lists of usernames. Unfortunately, it appears to join the names with OR rather than AND, so it reports those species unobserved by either user, rather than by both users. So, I can’t see any easy

Here is an example where I try to search for species of Periplaneta that neither my partner nor I have seen:
https://www.inaturalist.org/observations?place_id=any&subview=map&taxon_id=82233&unobserved_by_user_id=hydrophilus&unobserved_by_user_id=lemonsqueeze&view=species 1

As you can see, it just spits out a list of all 12 Periplaneta species currently on iNat, when I wanted it to show me the 9 species that neither of us have seen.

I’d like to see a simple way to compare a list of species found in a given location to the list of all species I have seen. For instance, I’m planning a trip to Death Valley, and I would love to be able to create a list of the species that occur within the park that I have never observed.

It would also be useful to compare observations within a place - if I’m surveying a specific area, what species have been observed in that place that I have not yet observed from that same place?

It would even be fun to be able to compare places to each other, and see the differences in species lists found there.

It’s still “experimental” but you can do some of this with the compare tool:

For example, these spring wildflowers of Illinois observed in 2018 but not yet in 2019:

Or vertebrates observed in Death Valley that you’ve never observed:

You have to narrow your searches to groups of taxa with fewer than 500 results, but other than that it’s super useful.

You can also add the query “unobserved_by_user_id=graysquirrel” to an observations search URL to get some of that info: https://www.inaturalist.org/observations?place_id=4504&view=species&unobserved_by_user_id=graysquirrel

Advantages Compare tool i

1. An actual UI to build your map choices
2. Supports other search criteria, not just taxa
3. Supports reordering of groups, which also swaps marker colors
4. Allows you to label each group of markers

Advantages of the Taxa Map include:

1. Has an intelligible URL
2. Not deemed “experimental”
3. Can default the center point and zoom level
4. Users can toggle on and off markers for GBIF observations
