no. you can’t do that in a single request. three different observations will require three different queries. in this particular case, because the combined result is not more than a few hundred observations, you could use the API and create a script to combine the result of the 3 queries into 1 result set, or to create a new query that filters by observation id, referencing all the ids from the 3 result sets.
short of that, usually, GLOBI provides a nice interface for looking for interactions between different organisms. it’s limited to a subset of properly licensed research grade observations, but it does a good job of merging similar observation fields together and allowing you to search taxonomic groups as opposed to exact individual taxa. there’s some discussion here on various ways to interact with their data set: https://forum.inaturalist.org/t/downloading-notes-and-observation-fields-tags-via-the-inaturalist-api/54985/2.
