Unique species in a list

Again, this is not something you can do on the explore page. And it is not something you can do with any of the available options.
For instance if you are interested in knowing what you contributed unique to the the Great Southern Bioblitz, you can filter it:
https://www.inaturalist.org/observations?place_id=any&project_id=great-southern-bioblitz-2020-cape-town&subview=grid&view=species
But the order is descending, and with over 2000 species, only the first 1000 are shown, and you are really interested in the tail end.
You can partly solve the problem, but doing it group by group: So let us take the vertebrates: Yes there are only 250 species so you can go to the end and find the species seen only once, and see if you can remember what you saw. Two problems: it is an iconic image - not yours - so you wont recognize the photo, and there is no other way to see who submitted it.

If you added your name to the filter, then it wont tell you how many were seen in the bioblizt, so you will still be in the dark.

However, there is a toolbox behind iNaturalist that you can use, and so we will use the "Compare Toolbox"
The reason it is not on the menus is that it is experimental, and is not so easy to use, and has some quirks. The most important quirk is that it is limited to 500 taxa. so for the Great Southern Bioblitz 2020, you will need to do this at least four times. But perhaps you are not interested in everything, just some things.
But here goes:
here is the tool: https://www.inaturalist.org/observations/compare
Note in this case that there are two lists or queries that we will compre
Now to get it to work, we need to add some filters.
The easiest way is to use the Explore to construct our filter.
Now the first query is the total list for the Bioblitz for southern Africa, but we know there are 2350 taxa, so we need to narrow it down. Let us take the vertebrates.
so query 1 which we will call Total Bioblitz looks like this:
https://www.inaturalist.org/observations?place_id=any&project_id=great-southern-bioblitz-2020-cape-town&subview=grid&taxon_id=355675
in the url bar (I copied it here for the link!!) select the text after the question mark and add it in the box after year 1: like so:
"place_id=any&project_id=great-southern-bioblitz-2020-cape-town&subview=grid&taxon_id=355675"
Now we need to create the explore filters for your data, which we will call "Linda's list" which looks like this:
https://www.inaturalist.org/observations?place_id=any&project_id=great-southern-bioblitz-2020-cape-town&subview=grid&taxon_id=355675&user_id=lindalakeside&view=species
so we need:
"place_id=any&project_id=great-southern-bioblitz-2020-cape-town&subview=grid&taxon_id=355675&user_id=lindalakeside&view=species"
and for fun I will include my own list (tony's list):
"project_id=great-southern-bioblitz-2020-cape-town&taxon_id=355675&user_id=tonyrebelo"

With those pasted in the boxes, we get (yes it is horrible, just click on it):
https://www.inaturalist.org/observations/compare?s=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

Note the three lines on top with our filters.
and then the table below, with the species names, followed by the totals in our three lists.
Note that the unique values are shown in yellow, and neither Linda nor I saw any species that were not in the total: of course not!! The total includes our lists.
Note you want the "Species" view with "totals" (dont press the map it will freeze), and
On the header of the columns, you can sort the columns. Play with them.

So what are we looking for: we want to see which total numbers in Linda's list equals the total list: that will be her unique contribution.
so fiddling with sorting the columns you can quickly see that Lindaw contributed all the records of:

Rufous-breasted Sparrowhawk Accipiter rufiventris
Mallard × Yellow-billed Duck Anas platyrhynchos × undulata

The Garden Route needs a fieldguide course Tony, please. Could a webinar work?

Thanks again for a great event - we will surely take part again if anything comes up.
We enjoyed it very much.
Just a couple of of quick questions please if I may:

for myself who want to get to know the flowers/plants, there are still a few of my observations that still needs identification, or will I have to let that go?
where can I find the Afrikaans common names of the flowers? For instance the Genus Roepera? What is it actually called? Or Stars? Is it just Stars/Sterretjie?
when we started with the Bioblitz I bought a book "Flowers of the Cape Peninsula, it did not help much, many of the ones I identified through the book was marked as errors and many I could not find? What book would you recommend?
Thanks,
Elize

Where can I find the Afrikaans common names of the flowers?
In theory, our common names should have been loaded onto iNaturalist. But with legal hassles of becoming a community it has not happened yet. But it is coming.
You have two choices:

If you only want Afrikaans names, then in your profile select language Afrikaans. But then you wont get English names, and with most Afrikaans names not yet loaded, that would be premature. You can also selct if you want the common names listed first, or after the scientific name or switched off.
If you click on the ID bar on your observations (any ID bar: at the top, on the side, or where an ID has been made), it will open the species page. On the "taxonomy" tab of the species page is a summary of all the scientific and common names used for the species. The Afrikaans names will be listed alongside the language, and ditto all the other languages that have names.

And there is a third option.

When you make an ID, try typing in the common name you know: iNat will find matches for you if they are in its dictionary - I find for quite a few species I know the common name better than the Latin, and I just use that instead.

Note though: as a rule - the Afrikaans names are generic or for groups. Many of the rarer species do not have Afrikaans names.

You can get very sophisticated if you like, but you need to learn your way around the site first:
