A way to see last added new species

Is there a way to filter out last new added species in a project or personal observation page? Or create a list of species with dates added or just in order of addition? I belive it can be done with downloading all data, but is it possible via website?

Not that I know of, I would like that as well.
The closest I’ve found is on your stats page you can get your lifers by month sorted by date posted and faves (I would prefer date observed) near the bottom by clicking on a month: https://www.inaturalist.org/stats/2020/you
You can also see which lifers you got on a particular day through your calendar, so you could go through the days to find the last one that has a lifer.


Thank you, will try to do it.) Hope something like that will appear for projects.

If you go to explore page, and go to filters, you can enter your own @name in the user box, then sort by date added. You can also enter the project name and sort by date added. Is this what you were looking for?

Not really, my friends are looking for a way to see which species were added last to the project for the first time, so like you don’t have to check each species for how many entries are there and if it is the first one, but have an ordered list of how they were added, maybe of only first observations of all species (or branches) or just species names, so you can say that these 5 or ten species were added last for the first time.


I see. I would definitely like this.

You can try using the recent_taxa feature, which @pisum helped make more accessible (though it still requires editing the URL). For example, here the spider species recently observed for the first time in Моско́вская о́бласть:

https://jumear.github.io/stirfry/iNatAPIv1_identifications_recent_taxa.html?place_id=133612&taxon_id=47119&rank=species&category=improving,leading&per_page=200 (it takes a moment to load)

Look for the check marks :heavy_check_mark: and ignore the Xs.


Thank you! Though a lot needs to learnt, but at least there’s an utility!


It looks like recent_taxa looks at the ID date and not the observation date?

Which makes sense, but isn’t what I expected at first, so I thought I’d point it out.


I also saw some taxons that were far from new but with :heavy_check_mark:, and I have no idea how to include both rg and need id, cause it creates me a link with only needs id when I mark both.

to clarify a bit, you’re looking for records with checks (representing yes) in the “Taxon = ID Taxon” column. for whatever reason, the results of this endpoint include associated parent taxa in some cases, but i don’t think those identifications are always the most recent of for the parent taxa. so you can avoid looking at those parent taxa records by looking only for the records with checks in that column.

sometimes records with the check have recent identification dates for taxa that are known to have been observed / identified much earlier. often these are cases where there was a taxon change, and the records returned here represent the first identification using the the new taxon id. that’s a limitation / quirk of the API endpoint. bouteloua might have other thoughts on usage, but that’s what i know from my limited experience looking at this.

add “&quality_grade=research,needs_id” to your URL.
