The filters are great if you want to e.g. search for observations made in a particular location, or sort them by date observed vs. uploaded etc. In addition, I find a couple other pages useful as well:
- The Species tab under Your Observations will show you your most commonly observed species and when you click on the number of observations per species it will bring up a list of those. Great if you want to know what you are seeing most frequently.
- The Calendar view is great if you want to get a list of all the observations made on a particular day, complete with info which of these were your first ever observations of that taxon.
Edited to add: If you have a particular theme (e.g. “my backyard”) you can add a tag and use that to search for all your observations with that tag. That might be another way to quickly “sort” observations into categories. You can add tags on the website or I think the Android app, I don’t think the iPhone app supports them.
