I would like to search for all observations that contain a certain taxon ID in the observation’s timeline. Specifically, the ID I’m looking for is: Sessile-flowered Trilliums (Subgenus Sessilia) . I tried &ident_taxon_id but that evidently does not work since the output contains observations that do …

Many hours later, here is a brief summary. Using a tool developed by @pisum : https://jumear.github.io/stirfry/iNatAPIv1_identifications?taxon_id=1024476&rank=subgenus&taxon_active=false&current=false&disagreement=true&observation_hrank=species&per_page=200&page=1 I reviewed 430 observations and re…

ident_taxon_ID will contain the specified taxon plus all of its children. The example observation you posted is a species nested within sessile-flowered trilliums, so that’s why it shows up. I’m not sure if there’s a way to specify only an exact taxon ID without including child taxa.

In the filters, for rank select “subgenus” for both high and low and you should get all observations of subgenus Sessilia https://www.inaturalist.org/observations?hrank=subgenus&locale=en-US&lrank=subgenus&place_id=97394&preferred_place_id=97394&taxon_id=1413201

[image] trscavo: Does this list contain duplicate observations? there could be multiple identifications for an observation. [image] trscavo: I’m afraid I need a list of observations it looks like the API is returning a little more than 8000 records. at 200 records per_page, you could …

I would like to know where to go to learn to search with taxon IDs! Where are these taxon IDs? Most of all I would like to filter for moths, that is, select Lepidoptera and omit butterflies both in Explore searching and in Identify. –Sorry this is off track from what you are requesting. Clearly the…

Yes, I think I understand the workflow you’re proposing. It might work if I can retrieve a list of identifications with inactive taxon_id 1024476 . Using the API docs you provided, I came up with the following query: /v1/identifications?taxon_id=1024476&rank=subgenus&taxon_active=false&current=false …

[image] trscavo: Is there a way to constraint the results to disagreeing IDs only? add &disagreement=true (which you narrow thing down to less than 700 records). if i’m understanding correctly what you’re trying to do, you may also want to add &observation_hrank=species (both of these would n…
