Here’s the situation: I’m looking at someone else’s observation to help ID and she has ID’d it as Kit Fox (and therefore I can see all Kit Fox observations in the inset map), but it could be a Gray Fox. Range information would be helpful. Is it possible to add all INat Gray Fox observations as a layer in the map so I can toggle back and forth between Kit Fox and Gray Fox?
not using the current interface, there are a couple of back-door ways you can kind of do this, but not formally.
If you click the Compare button on an ID, or the Suggestions tab on the Identify pop-up, you can view a side-by-side:
Beautiful. That’s exactly what I was looking for (and right under my nose!)
The taxa have to be closely related/you have to be a bit lucky for them to show up side-by-side.
One other (less easy) way to make comparison maps on iNaturalist (without downloading the data) is with the comparison tool. There may be other ways too. Not sure if it’s possible to load the pink range maps on the same map.
(You only actually need https://www.inaturalist.org/taxa/map?taxa=42070,42076, the rest recenters and resizes the map.)
One obvious way is just to toggle between two adjacent tabs on your browser!
