Description of problem:

Step 1: I tried to download data from audio observations for wintering European Robin from 4 months. The export page said I may copy a search URL, which I did. My pasted url included “month=1,2,11,12”.

Step 2: The output consisted of a csv with zero observations (2,9 Kb).

Step 3: I tried to troubleshoot it, figured out the URL works if I remove the month filter. Which gives me almost 40 times more data than I need.

I searched the forum and didn’t find anything related. Thought I might as well mention it, in case it’s a bug and not just a missing feature.

Can you paste the “create a query” url with month that is not working?

I created a query with months and was able to download the observations.

has[]=sounds&quality_grade=any&identifications=any&month=1,2,11,12&place_id=7161&subview=map&taxon_id=13094

Just pasted it again, page doesn’t respond, then remove the months part, page immediately refreshes and shows preview. In observation search the URL works as intended, which is expected, as I copied it from there

Are you starting on the explore page (which is what I’d recommend), or on the export page?

Ok, so a single value works. But if I add the second one, separated by comma or + (I tried..), then page refreshes and deletes the months filter altogether

On the export page, I went there from reading about API here

You can’t directly use the query params used on explore observations page on download page. The download query params are slightly different than what is used on search observation page.

Make your search query on the explore page, then click the download link in the bottom right of the filters. That will take you to the export page with the params in the format that the export page needs.

It works from the Explore page, I kinda forgot you can do this. The “you can copy and paste URL from other parts of the site” prompt on step 1 didn’t help

Yeah, it wasn’t obvious from the export page itself. It implied the opposite, though it may be incorrect translation. It says “You can also cut and paste the URLs of observations from other places on the site” in Russian

While the explore page and API uses

month=1,2,11,12

the export pages uses

month[]=1&month[]=2&month[]=11&month[]=12

The site says "You can also cut and paste an observations URL from another part of the site. " in English. That is usually true, but there are cases when it doesn’t work.

A bit misleading, may be useful to mention that it’s best to start from Explore.

I understang now that [] is for multiple choice options in export, just inconsistent in Explore. Thank you and tiwane for the explanation!
