Filling in the Gaps

[arthur-windsor]

A recent sighting of the week here on iNat was a rare Cicada. People in the article were mentioning filling in the gaps, as in there are zero observations for… whatever. I found that article to be a terrific story. Filling in the gaps with lucky finds. I’ve gotten lucky a few times. To target a gap, I like to look at the taxonomy, and then all subspecies added to the database. Looking to the right, one can hone in on those observations with only zeros and single digits, and those would be gaps. Is there a better way to find gaps? Also, a better way to find the biggest gaps in my area?
